Rabbi Shimon bar Yochai held that during the period of the Temple there were four distinct "camps," since the Ezrat Nashim constituted its own camp. However, in the period of Shilo there were only two camps. The Gemara struggles to identify which camp, according to Rabbi Shimon ben Yochai, did not exist in Shilo, since the Torah clearly assigns separate zones for each category of impurity - one who is impure from contact with a corpse, a zav, and a leper - implying the need for three distinct camps. Ultimately, the Gemara concludes that Rabbi Shimon's statement refers to an entirely different issue: during the period of Shilo, the Levite area did not function as a place of refuge for someone who killed unintentionally. This implies that in the wilderness the Levite camp did serve as a refuge zone, a point further supported by derashot on Shemot 21:13. A braita presents five different rabbinic opinions regarding which sacrifices were offered during the fourteen years after entering the Land, when the Tabernacle stood in Gilgal. Some maintain that only voluntary offerings brought by individuals were permitted. Rabbi Meir holds that meal offerings and Nazirite offerings were also brought. Rabbi Yehuda adds that even obligatory offerings could be brought in the Tabernacle (bama gedola), distinguishing between the central sanctuary and other locations. Rabbi Shimon limits which public offerings were brought. The Gemara then cites the scriptural basis for Rabbi Meir's position. Shmuel restricts the dispute between the rabbis and Rabbi Meir specifically to the obligatory offerings of a Nazirite. However, after Rava introduces a contradictory braita, the Gemara revises Shmuel's statement, concluding that the dispute concerns specifically the voluntary offerings of a Nazirite. The Gemara brings a source from the Torah for the opinion of the rabbis (the second view) in the braita.

Before the Tabernacle was erected, even blemished animals or male or female could be offered as sacrifices. This is derived from the juxtaposition of animals to birds in Bereishit 8:20, which describes the offerings Noach brought after the Flood; since blemishes do not disqualify birds and females can be brought as burnt offerings, they likewise did not disqualify blemished animals or females. However, if an animal was missing a limb, it could not be offered. This is learned from Bereishit 6:19, "From all live animals," implying that only fully intact animals were acceptable. The Gemara asks why this verse is not used to exclude a treifa, and answers by identifying a different source for excluding a treifa. Only kosher animals could be offered, even before the Tabernacle was built. But since this was before the Torah was given, how could there be a distinction between kosher and non‑kosher animals? Rabbi Shmuel bar Nachmani explains that the distinction refers to animals that would eventually be considered kosher. Noach brought two of each species into the Ark, but of the kosher species he brought seven of each so that he would have animals available for sacrifice after the Flood. How did Noach know which animals would later be deemed kosher? Either this was revealed miraculously, or the animals entered the Ark on their own, with the kosher species arriving in groups of seven while the non‑kosher species arrived only in pairs. There is a tannaitic dispute regarding whether, before the Tabernacle was erected, people brought only burnt offerings or also peace offerings. This debate hinges on whether the descendants of Noach were permitted to bring peace offerings, a question derived from Hevel's sacrifice - specifically the phrase "from the fat thereof" - and from a verse in Shir HaShirim 4:16. A challenge is raised against the opinion that peace offerings were not brought, based on Yitro's offering of peace offerings. The resolution depends on whether Yitro's sacrifice occurred before or after the giving of the Torah. Indeed, there is a tannaitic dispute about the timing of Yitro's arrival, rooted in the question of what he heard that motivated him to come and convert: Israel's victory over Amalek, the giving of the Torah, or the splitting of the Sea. Non‑Jews may offer sacrifices anywhere and at any time, since the prohibition against sacrificing outside the Temple applies only to Jews. However, Jews may not serve as their agents in performing the sacrifice. The Gemara relates a story about Ofrah Hermiz, the mother of the Persian king Shapur, who asked him to bring a sacrifice on her behalf. Rava advised her on the matter but arranged for non‑Jews to perform the actual sacrificial act. In the desert, the Israelites were permitted to eat kodashim kalim anywhere within the camp. Rav Huna stated that they could eat them anywhere that Jews were present. The rabbis sought to clarify his statement, given that the desert encampment clearly consisted of distinct camps, while his words seemed to imply otherwise.

It is forbidden to offer any sacrificial item outside the Azara. This prohibition applies both to valid offerings and to offerings that became invalid in the kodesh—meaning either after they were brought into the Azara or after they were slaughtered. A braita derives the various valid and invalid items for which one is liable if offered outside the Azara from derashot on the verses in Vayikra 19:8–9. The Mishna rules that if one offers outside the Temple an olive‑bulk composed of a combination of meat and imurim (the fatty portions burned on the altar) of a burnt offering, one is liable. This implies that in the case of a peace offering, the two would not combine, since the meat is designated for consumption while the imurim are designated for burning. Although this inference is supported by Tosefta Meila 1:15, that Tosefta appears to contradict a Mishna in Meila 15b. The Tosefta states that in a burnt offering, the meat and imurim combine for pigul, notar, and impurity, whereas the Mishna states that they combine for pigul and notar in all types of offerings, not only burnt offerings. The Gemara resolves these contradictions by explaining that the terms pigul and notar refer to different cases in each source. The distinction regarding pigul is between (1) eating pigul and (2) having a pigul thought concerning eating or burning the combined olive‑bulk. The distinction regarding notar is between (1) eating leftover meat and imurim after their designated time and (2) a case where parts of an animal (a combined olive‑bulk of meat and imurim) remained from an animal that had been lost before the blood was sprinkled. Since in a peace offering the meat and imurim are destined for different places - human consumption and the altar - they cannot combine in situations where the law depends on their being in the same place (such as pigul thought or leftover parts from before the sprinkling of the blood). However, they can combine in a case involving the eating of disqualified parts. This interpretation of the Tosefta aligns with the view of Rabbi Yehoshua, who discusses a case in which only an olive‑bulk of the animal remains before the sprinkling of the blood. Items that are entirely burned on the altar - such as the kometz, frankincense, the mincha of the priests, and similar offerings - also incur liability if offered outside. However, there is a dispute between the rabbis and Rabbi Elazar regarding whether liability applies for offering merely an olive‑bulk or only when the entire item is burned outside. A braita is then cited concerning the requisite amounts for liability when offering a incense outside and for burning incense inside. Initially, a question is raised about the incense and the meaning of the braita. After Rabbi Zeira resolves the question, he raises a further difficulty based on a statement of Rav regarding Rabbi Elazar's opinion about the required amount for liability when offering incense outside the Temple. Rava and Abaye each propose solutions, but both are ultimately rejected.

What is the source for the opinion of the rabbis in the Mishna that one who slaughters outside and then offers it outside is liable? Three possible derivations are presented, and the Gemara raises difficulties with the different possibilities. What is the source for the law in an upcoming Mishna that one who sprinkles the blood outside the Temple is liable? Rabbi Akiva and Rabbi Yishmael each derive it from different verses. The Gemara then asks: what does each of them learn from the verse that the other used for this prohibition? What is the source for the law in an upcoming Mishna that one who takes a kometz (a handful of a meal offering) or one who accepts the blood outside is not liable? The Gemara demonstrates that there is no basis to assume liability and explicitly rejects a suggestion that there might be reason to think otherwise. The verse forbidding slaughter outside includes three distinct phrases that specify where the prohibition applies and where it does not. What is derived from the use of all three? Ulla and Rava disagree about whether one is liable if they slaughter on the roof of the Heichal, which is dependent on how these phrases are understood. Rabbi Yochanan and Reish Lakish dispute whether one is liable nowadays if one slaughters outside the area where the Azara once stood. Their debate hinges on whether the sanctity of the First Temple remains in effect or whether it was nullified with the Temple's destruction.

Charts of Machloket R Akiva/R Ishmael & Rava/Ulah - Document for Daf 107 by Simon Wolf

Chapter 13! On offering sacrifices in locations that are not specified, and therefore also prohibited for sacrifices. The new mishnah raises the cases of offering outside the Temple. With a difference of approach between Rabbi Yossi HaGalilee and the sages. Plus, a ritually pure person who ate that which was impure would be exempt from a sin-offering, and the mishnah provides the explanation why. Also, the sources for all this in verses. Also, a focus on why this kind of offering outside of the Mishkan (or Temple) can't carry a "karet" punishment as derived from logic - though the Gemara first attempts to show how that logic would be upheld (by Rabbi Avin - and then knocked down by Rava).

Rav held that Moshe served as a kohen gadol. Four tannaitic sources are brought to challenge this position, but each one is ultimately resolved. A braita is then cited to show that whether Moshe was a kohen gadol is itself a tannaitic dispute. One of the tannaitic views in that debate cites a statement of Rabbi Yehoshua ben Korcha: whenever the Torah uses the expression charon af,  anger, it implies some concrete action or consequence. His statement is challenged by the verse in Shemot 11:8, where Moshe becomes angry at Pharaoh, yet no action seems to follow. Reish Lakish resolves this by saying that Moshe slapped Pharaoh in the face. This explanation is challenged by another statement of Reish Lakish, in which he says that Moshe showed respect toward Pharaoh. Two answers are offered to reconcile these conflicting statements. Two verses are then brought to support the principle that one must show respect to a king, even a wicked king, one verse concerning Pharaoh and another concerning Ahab. Earlier, a source had referred to Moshe as a king. However, Ulla stated that Moshe desired to be king but was not granted that status. Rava resolves this by qualifying Ulla's statement: Moshe wished for his sons to inherit kingship, and that request was denied, but Moshe himself was indeed considered a king. The Gemara then asks: from where do we derive that kohanim with any type of blemish are entitled to receive portions of the priestly gifts? Four braitot are cited, each offering a drasha that builds upon the previous one. The Mishna states that those who cannot serve in the Temple do not receive a portion, which seems to contradict the ruling regarding blemished kohanim. Furthermore, the implication that those who do serve may eat is difficult in the case of impure kohanim during communal offerings, where they may serve, yet do not receive a portion. The Gemara explains how this contradiction is resolved. Rav relates that Rabbi Elazar son of Rabbi Shimon was once in the bathroom and devised various arguments that a tevul yom might use to claim a share of sacrificial portions. Yet for every argument he proposed, a pure kohen could cite a verse proving that a tevul yom is excluded, since he cannot perform the Temple service. The Gemara then asks: how was Rabbi Elazar able to think Torah thoughts in the bathroom, something that is normally forbidden?

Study Guide Three additional resolutions, bringing the total to five, are proposed to reconcile the contradiction between the two baraitot, each of which presents a different view of Rabbi Shimon on whether an onen may eat the Pesach offering at night. A challenge is raised against the third resolution, evidence is presented in support of the fourth, and a statement of Rava bar Rav Huna is cited to bolster the fifth.

If mixtures of an offering are cooked together with those of another offering of a different status, or with non-sacred food, the resulting food assumes the status of the more stringent offering, as stated in Vayikra 6:20. Although this law is presented in the context of the sin offering, a drasha on the verse in Vayikra 7:37 which juxtaposes various types of offerings, teaches that this principle applies to all sacrifices. Each offering mentioned in that verse serves to transmit a particular law to the others. A braita quoted in the name of Rabbi Akiva derives the law of foods cooked together from the word 'mincha' in that verse, since the same rule appears in the context of the meal offerings in Vayikra 6:11. The sin offering in the verse, however, is used to teach other laws. While the braita derives three laws from the sin offering - that it cannot be purchased with second tithe money, must be offered during the day, and that all actions must be performed with the right hand - the Gemara limits this to two, and possibly even to one, since the other laws are taught explicitly regarding different offerings. Rava raises two questions concerning blood on a garment: one about the Temple laws of laundering blood from a sin offering, and the other about chatzitza (interposition) in the mikveh. He resolves the first question, but the second remains unanswered. The Mishna lists cases where kohanim do not receive a portion of the meat. If they are unable to perform the sacrifice due to impurity or similar disqualifications, they cannot receive a share. However, blemished kohanim, though not permitted to sacrifice the sacrifices, but are nevertheless entitled to receive a portion of the meat.

Chullin Shiur #50 Daf 9b- Sofek Tumah Abaye-Rava, Rambam Rashba

Rabbi Tarfon and the Rabbis disagree about whether merika and shetifa of metal utensils that were used for cooking sacrificial meat are necessary daily during the holidays, or whether on the holidays one also needs to perform it only after the holiday ends. What is the basis of Rabbi Tarfon's position to be lenient on the holiday? The time for performing merika and shetifa is after the time for eating the sacrifice has passed. From where is this derived? Rebbi and the Rabbis disagree about whether merika and shetifa are both done with cold water, or whether merika is with hot water and shetifa with cold. Even according to Rebbi, who holds that both are with cold water, one would still be required beforehand to boil the pot with hot water to remove the taste of the meat that has now become notar, left beyond the time the sacrifice can be eaten. If mixtures of an offering are cooked together with those of another offering of a different status, or with non-sacred food, the food takes on the status of the more severe offering, as stated in Vayikra 6:20. This law is only applicable if flavor is imparted. The details of this law are analyzed. A question is asked: why does the positive commandment to eat sacrificial meat not override the negative commandment not to eat disqualified meat? Rava answers that this principle does not apply in the Temple. Rav Ashi answers that there is both a negative and a positive commandment not to eat the meat, which is why the positive commandment to eat it does not override. The verse relating to this law is mentioned in the context of the sin offering. From the verse in Vayikra 7:37, which mentions various different offerings, the sages learned that the laws of each type apply to all the other types as well. From the sin offering in that verse, they derive that this law applies to all sacrifices. What is derived from the other words in that verse?

The same issue raised on the previous page regarding laundering vessels removed from the Azara is now applied to breaking earthenware vessels and performing merika (scrubbing) and shetifa (rinsing) of metal vessels. If these vessels are punctured and lose their status as valid utensils, how can the mitzva of breaking or cleaning them be fulfilled? Reish Lakish teaches how to handle a priestly garment that becomes impure, since it cannot be torn. Rav Adda bar Ahava challenges his suggestion, but the Gemara resolves the difficulty. The Gemara raises a difficulty with the obligation of laundering: how can blood be laundered in the Azara if Rav Nachman, quoting Raba bar Avuha, rules that blood of a sin offering and stains from nega'im require cleansing with the seven prescribed detergents, one of which is urine? According to a braita, urine may not be brought into the Temple. The resolution is to bring the urine mixed with saliva (rok tafel). The Mishna teaches that vessels in which sacrificial meat was cooked, or into which boiling liquid was poured, require merika and shetifa, whether from kodashei kodashim or kodashim kalim. Rabbi Shimon disagrees, exempting kodashim kalim from this requirement. A braita explains that the words in the verse in Vayikra 6:21, "that which was cooked in it," extend the law to include pouring boiling liquid into a vessel. Rami bar Chama raises the question of whether meat suspended in the air of the oven counts as cooking for the purposes of requiring breaking the oven. Rava brings a source to answer this question, but it is rejected. A statement of Rav Nachman in the name of Raba bar Avuha is also cited to answer the question, but it too is rejected. A practical case is cited where an oven was plastered with fat, and Raba bar Ahilai forbade eating bread baked in it forever, lest one come to eat it with dairy dip (kutach). This ruling is challenged by a braita that prohibits kneading dough with milk or plastering an oven with fat, but allows use once the oven is reheated (as koshering removes the flavor). Raba bar Ahilai's ruling is therefore rejected. Ravina asks Rav Ashi why, if Raba bar Ahilai was refuted, Rav ruled that pots on Pesach must be broken. Rav Ashi explains that Rav understood the braita to be referring to metal vessels. Alternatively, one can distinguish between earthenware ovens, whose heat is on the inside (so koshering works), and earthenware pots, which are heated from the outside and cannot be properly koshered.

Study Guide The Gemara examines the debate between Rabbi Elazar and Rabbi Yehuda regarding whether leather garments stained with blood from a sin offering require laundering. A braita cites verses in the Torah as the source for each position, with the disagreement hinging on how to interpret the term "beged." Rabbi Yehuda understands "beged" to include any material potentially capable of receiving impurity, while according to Rabbi Elazar it includes sackcloth and other types of clothing that are actually susceptible to impurity. Abaye and Rava identify three practical differences that emerge from their interpretations. Another braita establishes that only the specific area of a garment where blood lands requires laundering, not the entire garment. The Gemara then derives from the Mishna that hides are subject to laundering, but cites a conflicting source related to Shabbat observance, which rules that rinsing a hide with water is not considered laundering. Abaye resolves the contradiction by attributing one view to the Rabbis and the other to "others," who include hides in laundering. Rava challenges this, citing verses that explicitly mention leather, and concludes that the distinction lies between soft and hard hides. After raising two difficulties with his own explanation, Rava proposes a third approach: differentiating between scrubbing, which constitutes laundering, and merely pouring or soaking with water, which does not. The Gemara then cites a braita deriving from verses that laundering, breaking earthenware vessels, and rinsing copper vessels must all be performed in the Azara. The Mishna rules that laundering is the only stringency unique to the sin offering compared to other offerings, though the Gemara questions this in light of other possible stringencies. The Mishna further teaches that if a garment with blood, an earthenware vessel, or a copper vessel in which meat was cooked leaves the Azara and becomes impure, the impurity must first be removed - by tearing, making a hole, or otherwise invalidating the vessel - and then the item is returned to the Azara to be laundered, broken, or rinsed. Ravina challenges the ruling that an impure garment is torn outside and then laundered inside: if tearing removes its status as a garment, how can the obligation to launder be fulfilled? The Gemara clarifies that the case refers to tearing along the length without splitting it into two pieces, which is sufficient to remove impurity while still leaving it with the status of a garment for laundering.

The Mishna rules that laundering is the only stringency unique to the sin offering compared to other offerings, though the Gemara questions this in light of other possible stringencies. The Mishna further teaches that if a garment with blood, an earthenware vessel, or a copper vessel in which meat was cooked leaves the Azara and becomes impure, the impurity must first be removed - by tearing, making a hole, or otherwise invalidating the vessel - and then the item is returned to the Azara to be laundered, broken, or rinsed. Ravina challenges the ruling that an impure garment is torn outside and then laundered inside: if tearing removes its status as a garment, how can the obligation to launder be fulfilled? The Gemara clarifies that the case refers to tearing along the length without splitting it into two pieces, which is sufficient to remove impurity while still leaving it with the status of a garment for laundering.    

Study Guide Rami bar Hama asks Rav Chisda whether blood that splashes onto a garment already impure requires laundering. Rav Huna son of Rav Yehoshua explains that the question hinges on whether laundering is unnecessary only when impurity and disqualification occur sequentially, or even when they occur simultaneously. Rav Chisda connects the issue to a dispute between Rabbi Elazar and the rabbis regarding the status of mei chatat that became impure, as interpreted by Abaye. To clarify Abaye's understanding, the Gemara presents a broader disagreement among Raba, Abaye, and Rava about the nature of the disagreement between Rabbi Elazar and the rabbis. A braita teaches that only blood fit for sprinkling requires laundering, excluding blood already disqualified. Rabbi Akiva rules that blood which had a moment of fitness and was later disqualified does require laundering, while Rabbi Shimon maintains that disqualified blood never requires it. The Mishna rules that blood splashed from the neck of the animal, or from the altar's corner or base, does not require laundering, nor does blood spilled on the floor and later gathered, since only blood received in a vessel and fit for sprinkling requires laundering. Two braitot are cited to demonstrate how these laws are derived from verses in the Torah. The Gemara further clarifies that the requirement of being "capable of sprinkling" excludes cases where less than the requisite measure was received in each vessel. Rava explains that this principle is rooted in a drasha on the verse in Vayikra 4:6. After presenting several drashot on the different words of that verse, the Gemara analyzes them both in relation to one another - explaining why each was necessary - and in relation to other statements. The Mishna continues with blood splashed on the hide: before flaying it does not require laundering, but after flaying it does. Rabbi Elazar limits laundering to the place of the blood and only where the material is susceptible to impurity. A braita extends laundering obligations to garments, sackcloth, and hides, and specifies that laundering, breaking of earthenware vessels, and rinsing of copper vessels must all be performed in a sacred place. Laundering is a stringency unique to the sin offering compared to other kodshei kodashim.

If one sacrifice is more frequent (tadir), but another is more sanctified, which takes precedence? Three cases are brought from the first Mishna of the chapter (Zevachim 89) to prove that frequency takes precedence, but each is rejected in the same manner. A Mishna relating to the order of blessings in kiddush and a statement of Rabbi Yochanan are also cited to support the principle of frequency, but these too are rejected. Finally, an inference is drawn from the Mishna in Zevachim 90, which implies that if a peace offering and a guilt or sin offering were before the kohen, and both were from that day, the guilt or sin offering would take precedence - even though peace offerings are more common. To reject this proof, Rava distinguishes between "frequent" and "common." Rav Huna challenges Rava's distinction from a source about brit mila and Pesach, where brit mila is considered tadir. His difficulty, however, is resolved in two possible ways. Another question arises: if a less frequent sacrifice is slaughtered first and then they realize their error, should someone mix the blood (to prevent coagulation) while the more frequent sacrifice is offered first, or should they complete the one already begun? Four sources are brought to address this issue (three of which were also cited earlier), but all attempts are rejected. In the Mishna, Rabbi Shimon and Rabbi Tarfon disagree about whether oil can be offered in the Temple as a voluntary offering. Shmuel explains that according to Rabbi Tarfon, who permits it, only a kmitza (handful) is burned on the altar, while the remainder is given to the kohanim to eat. Rabbi Zeira supports Shmuel's view from the Mishna, while Abaye presents an alternative opinion: that a voluntary oil offering is burned in its entirety, also citing proof from the Mishna. A Tosefta raises a difficulty for Shmuel, but it is resolved. The Gemara then suggests that this is a tannaitic debate; after an attempt to refute the suggestion, it is upheld. Regarding wine, there is likewise a debate about whether it can be brought as a voluntary offering. Shmuel explains that according to Rabbi Akiva, it may be offered, with the wine sprinkled on the altar. However, this raises the issue of partially extinguishing the altar's fire, which is forbidden by Torah law. Others maintain that the wine is poured into the cups at the top of the altar. The Gemara concludes that this debate parallels the dispute between Rabbi Shimon and Rabbi Yehuda (usually in the context of melacha on Shabbat) about whether one is liable for an act intended for one purpose that incidentally results in a prohibition - even when one has no interest in the prohibited outcome.

  Raba and Rav Chisda disagree on two issues. If items were not completely consumed on the altar, removed before midnight, and returned after midnight, at what point are they considered "consumed" such that they no longer need to be put back on the altar if removed again (assuming they have not yet turned to ash, in which case they would not need to be returned)? Raba rules that they are considered consumed at midnight of the following night, while Rav Chisda holds that the cutoff is dawn. If the items were not returned until after dawn, Raba still maintains that midnight of the next night renders them consumed, whereas Rav Chisda insists they can never be rendered consumed. Rav Yosef challenges the premise of both opinions, which assume that items not on the altar at midnight cannot be rendered consumed. He argues instead that midnight itself renders all items consumed, even if they were removed before midnight and not yet returned to the altar. Rava asked Raba: If items remain at the top of the altar all night, does that prevent them from becoming disqualified through lina (remaining overnight)? Raba answered that they are not disqualified, but Rava did not accept this response. A braita is cited, providing a source in the Torah that the ramp and sanctified vessels also sanctify disqualified items. If such items are placed on the ramp or the altar, they do not need to be removed. Reish Lakish posed a question to Rabbi Yochanan regarding disqualified items placed in sanctified vessels. Initially, Rabbi Yochanan thought the question was whether they were sanctified to the extent that they could not be redeemed. Reish Lakish clarified that he was asking whether items placed in sanctified vessels could be brought ab initio on the altar. Rabbi Yochanan answered yes, based on the Mishna, but this answer was rejected since the Mishna could be read differently. The Gemara then asks: Does the airspace of the altar sanctify items? At first, it attempts to prove that the airspace does sanctify from the Mishna's statement: "Just as the altar sanctifies, so does the ramp." Items sanctified by the ramp must be carried through the altar's airspace to reach it. If the airspace does not sanctify, then carrying them would be akin to removing them, and once removed, they could not be returned. However, this proof is rejected, since it is possible to bring them to the altar by dragging rather than lifting. Rava bar Rav Chanan then attempts to prove the opposite from the case of a bird burnt offering brought at the top of the altar. If the airspace sanctifies, then there could be no case of pigul (disqualification due to improper intent), because as long as the offering remains on the altar, it could be sacrificed even the next day. Thus, a thought to offer it the next day would not constitute pigul. Rav Shimi rejects this argument, explaining that one could still have a pigul thought to remove the offering and then put it back on the altar the next day, which would indeed be disqualifying.

The final difficulty from our Mishna against Rav Ashi's explanation of Rabbi Eliezer's opinion in the Mishna in Parah - that Rabbi Eliezer maintains we do not view any given drop of the mixture as containing elements of both (no bila) - cannot be resolved in the same way as the earlier difficulties. To address this challenge, Rava offers an alternative explanation for the Mishna and braita cited against Rav Ashi. He clarifies that these sources are not discussing a case of blood that became mixed together, but rather cups of blood that became intermingled. Therefore, they are not relevant to the question of how to regard a portion of blood drawn from a mixture of bloods. The Gemara then raises a difficulty on Rava's approach, citing a braita in which Rabbi Yehuda explicitly states that Rabbi Eliezer and the rabbis do, in fact, disagree about blood that was mixed together. In conclusion, the Gemara suggests that this is a tannaitic dispute regarding whether or not they disagreed about mixed blood. One of the cases in the Mishna involves a mixture of bloods designated for placement on the top of the altar together with bloods designated for the bottom. Rabbi Eliezer permits the blood to be offered above and then below, while the rabbis forbid it. Abaye limits this debate to blood from a sin offering mixed with blood from a burnt offering, but not to blood from a burnt offering mixed with the remainder of blood from a sin offering, since the location for pouring the remainder is the same as that of the burnt offering. Therefore, even the rabbis would permit it. Rav Yosef disagrees, maintaining that the remainder is not poured on the side of the altar like the burnt offering, but rather placed on the surface of the base (a protrusion one cubit wide). Reish Lakish aligns with Abaye, while Rabbi Yochanan (or Rabbi Elazar) aligns with Rav Yosef. Three difficulties are raised against the position of Rav Yosef and Rabbi Yochanan, but each is resolved. The Mishna teaches that there is no dispute in a case where blood from a sin offering designated for the outer altar becomes mixed with blood from an offering designated for the inner altar. All agree that such a mixture is disqualified. If it was nevertheless offered, what are the rules—does the order of placement, inside first or outside first, make a difference?

A contradiction between the Mishna in Mikvaot 10:6, which seems to be Rabbi Yehuda's position anrules according to majority, and Rabbi Yehuda in the braita, who follows appearance, is resolved in two ways. Abaye suggests that in the braita, where the position is stricter, Rabbi Yehuda is quoting Rabban Gamliel, who was known for his stringency in cases of nullification, as he did not allow nullification at all in mixtures of the same type (min b'mino). Rava, however, explains that the more lenient opinion in Mikvaot refers to a case where only the outside of the cup was impure. By Torah law, the mikveh waters need only pass over the rim, not fill the cup. Since the requirement to fill the cup is rabbinic, there is room for leniency. Rabbi Elazar disagrees with Reish Lakish regarding pigul and notar that became mixed together. He holds that just as mitzvot do not nullify one another, prohibitions likewise do not nullify each other. This principle is based on Hillel, who would eat matza and maror together on Pesach to fulfill the commandment that they be eaten simultaneously. If mitzvot could nullify one another, the strong taste of the maror would cancel the taste of the matza, preventing fulfillment of the mitzva of eating matza in that manner. Regarding min b'mino, a mixture of the same type, there is a dispute between Rabbi Yehuda and the rabbis as to whether it can be nullified. A similar debate appears in the Tosefta Taharot 5:3 between Rabbi Eliezer ben Yaakov and the rabbis in a case of a shard that absorbed urine: can it be purified by soaking or rinsing in urine? In the Mishna, there is also a debate between Rabbi Eliezer and the rabbis concerning blood mixed with problematic blood. The question arises: does Rabbi Eliezer disagree in both cases - disqualified blood and dam hatamtzit (the blood that flows from inside the animal) - or only in the latter case? The Mishna explores various scenarios of blood mixtures and clarifies where Rabbi Eliezer and the rabbis differ.

Four difficulties are raised against Rava's explanation of Rabbi Shimon—that he permits sanctified items to be potentially disqualified only after the fact, but not ab initio. Most of these challenges are resolved, though not all. In the fourth difficulty, the case of the leper's guilt offering is discussed. The Gemara then seeks to clarify how the log of oil is brought in the case of a leper when sacrifices have become intermingled.

If sacrifices of the same type become intermingled, the Mishna rules that they are offered for "whichever owner they belong to." However, in cases where smicha is required, how can the sacrifice be brought, since one cannot perform smicha on another's offering? Rav Yosef explains that the Mishna must be referring to women, who are not obligated in smicha. Men's sacrifices, by contrast, would not be offered; instead, they would be left to graze until they developed a blemish and then sold, with new animals purchased for the altar. Abaye raises a difficulty from a braita that discusses public and individual sacrifices that became mixed both before and after slaughter and were nevertheless offered. Since public sacrifices are brought by men, the braita must also be referring to individual sacrifices brought by men. Rava resolves this by reinterpreting the braita, noting a difficulty in its plain reading. He explains that it refers only to a case where the blood of the animals was mixed after slaughter, and not to intermingling of live animals. In the braita cited by Abaye, Rebbi rules that if the blood of two animals was mixed in one cup, the kohen may combine the sprinkling for both sacrifices, but only if there is enough blood for each. A difficulty is raised against Rebbi from another braita in which he quotes Rabbi Eliezer regarding the red heifer purification waters, where no minimum amount is required for sprinkling. The same should apply to blood. Two answers are offered: either the purification waters differ from blood, or Rebbi was not stating his own view but merely quoting Rabbi Eliezer. Rami bar Hama poses two questions concerning a firstborn animal that became blemished. Rabbi Yosi bar Zevida attempts to answer from the Mishna about firstborns intermingled with other sacrifices, but his answer is rejected. The Mishna states that only sin and guilt offerings cannot be intermingled, since their differences are identifiable. The Gemara considers whether other offerings might also fall into this category, but all such suggestions are rejected. If a guilt offering becomes mixed with a peace offering, they are offered according to the stricter requirements of the two. This could potentially cause sanctified items to be disqualified. Rabbi Shimon does not have an issue with this, but the rabbis disagree and do not allow it. Rava limits Rabbi Shimon's ruling to a post facto situation and does not permit it ab initio.

Two additional answers are offered to explain why, in the Mishna, the animal is not nullified among the others if one follows Rabbi Yochanan, who holds that only items sold exclusively by unit are not nullified in a mixture. The first answer is that the Mishna follows Rabbi Yehoshua according to Rabbi Yehuda in the case of a litra of dried figs, teaching that items sometimes sold individually are not nullified. The second answer is that live animals are considered significant and therefore cannot be nullified. The Gemara continues to ask why animals designated for sacrifices, when intermingled with an animal forbidden for benefit, are all left to die. It suggests resolving the issue through the laws of probability: one could remove an animal at a time and assume each emerged from the majority of permitted animals. The difficulty is that, according to halakhic rules of probability, this only applies once an animal has already been separated, allowing us to presume it came from the majority. But if the animals remain fixed and one is taken directly from the group, the law treats it as either permitted or forbidden (50/50), with no majority to rely upon. The Gemara further proposes creating a situation where the animals scatter from their fixed location, so they are no longer considered fixed, and each could then be assumed to come from the majority. Rava offers three explanations why this solution fails, the first two of which are rejected. The final answer is that, although theoretically possible, it was prohibited by decree, lest people apply the same reasoning in cases where the animals remain fixed. Rava concludes that since the animal is not nullified by rabbinic decree, if any of the animals in the mixture are sacrificed on the altar, they do not achieve atonement, and a new sacrifice must be brought. Rav Huna raises a difficulty with this explanation based on two Mishnayot in Kinnim 1:2 and 3:1. The difficulty is resolved by explaining that Rava holds live animals and birds can be rejected from the altar, whereas the Mishna rules that they cannot.

The Gemara in Sanhedrin 65b describes Rava making a “man” and Rav Oshiya and Rav Chanina making a calf.

In Zevachim 59, a difficulty was raised against Rav's position that a sacrifice slaughtered while the altar was damaged is disqualified. The contradiction came from a statement of Rav that incense could be burned even when the altar was removed. It was resolved by suggesting that just as Rava explained, Rabbi Yehuda distinguished between blood and burning (and required the altar for blood), so too Rav distinguished between blood and burning the incense (and required the altar to be complete for slaughtering and sprinkling the blood). Where did Rava make that statement? A lengthy argument between Rabbi Yehuda and Rabbi Yosi is brought to provide background. Then a proof is offered for Rava's understanding of Rabbi Yehuda, based on Rabbi Yehuda's suggestion regarding the blood from the Paschal sacrifices that spilled on the floor, but the proof is rejected. Rabbi Elazar brings a source to derive the requirement for the altar to be complete  to permit eating the remains of the meal offerings and other food of kodashim kodashim. Is a complete altar required for eating kodashim kalim? Abaye brings a braita of Rabbi Yishmael proving that the second tithe cannot be eaten in Jerusalem when there is no Temple. He first attempts to derive it from the firstborn by logical inference, but then derives it from a juxtaposition (heikesh). Abaye's explanation of Rabbi Yishmael leads to the understanding that kodashim kalim cannot be eaten when there is no altar. Rabbi Yirmia vehemently disagrees with Abaye, calling him a 'stupid Babylonian,' due to a contradiction between two braitot, which he resolves by differentiating between kodshai kodashim and kodashim kalim regarding this law.  

In Zevachim 59, a difficulty was raised against Rav's position that a sacrifice slaughtered while the altar was damaged is disqualified. The contradiction came from a statement of Rav that incense could be burned even when the altar was removed. It was resolved by suggesting that just as Rava explained, Rabbi Yehuda distinguished between blood and burning (and required the altar for blood), so too Rav distinguished between blood and burning the incense (and required the altar to be complete for slaughtering and sprinkling the blood).

Rav and Levi disagree about whether there was truly no base on the south and east sides of the altar, or whether a base existed but the blood could not be poured there. Various sources are cited to challenge both opinions, and each difficulty is addressed and resolved. One of the sources provides a detailed description of how the altar was constructed. Rava, based on a drasha from a verse in Shmuel I 19:19, explains how David and Shmuel determined that the Temple would be built specifically in the territory of Binyamin and precisely at that location—not elsewhere. Although Ein Eitam was actually higher in elevation, two reasons are given for why that site was ultimately rejected.

"A pillar of the Jewish community of Buenos Aires, an ardent Zionist, a loving family man, I am proud to be his granddaughter, and he is missed." Communal peace offerings and guilt offerings have the same requirements. The derivation that communal peace offerings are slaughtered in the North is initially brought from a verse in Vayikra 23:19–20, but this is rejected because it relies on a juxtaposition built upon another juxtaposition - deriving communal peace offerings from sin offerings, which themselves are derived from burnt offerings. Instead, Bamidbar 10:10 presents a direct juxtaposition between communal peace offerings and burnt offerings, making it a stronger source. This raises two questions: why are communal peace offerings juxtaposed to sin offerings in the first verse, and why, in the verse regarding the ram offering of the nazir, is the peace offering juxtaposed with both the sin and burnt offering? One answer is given for the first question, and two possible answers are offered for the second. The Mishna introduces kodshim kalim, sacrifices with a lower level of sanctity. These may be slaughtered anywhere within the Azara and eaten by the owner anywhere in Jerusalem. The first examples cited are the thanksgiving offering (toda) and the peace offering (ram) of the nazir, as they share the same requirements and must be consumed within one day and one night. What is the source that kodshim kalim must be eaten in Jerusalem? Abaye and Rava each derive it differently from Vayikra 10:14. However, Abaye's interpretation is preferred due to a difficulty found in Rava's approach. Regular peace offerings may be eaten over two days and the intervening night. The Gemara cites three verses concerning peace offerings where slaughtering is mentioned, and derives a distinct law from each one—including the rule that they may be slaughtered anywhere in the Azara. Rabbi Eliezer and the first tanna disagree on how these verses should be interpreted and what halakhot can be extracted from them. One of the laws derived from these verses is that the door to the Sanctuary (Heichal) must be open when peace offerings are slaughtered. The Gemara proceeds to analyze the scope and implications of this requirement.

1 section- 6 teachings of Rava regarding wrong intent and the korban ola

The braita in Zevachim 51 extrapolates from the third mention (by the nasi) of the base of the altar that for all sacrifices on the outer altar the remainder of the blood is poured on the base, the yesod. The braita then raises a question: perhaps the extrapolation should be different — that the sprinkling of sacrificial blood on the outer altar must be performed only on the sides where there is a base, i.e., not on the southeast corner, since the base did not extend there. A difficulty on that suggestion is drawn from the verse's wording. The verse states "to the base of the altar of the olah," which suggests relevance to all sacrifices on the outer altar rather than only to the olah. But the sin offering, which is placed on the outer altar, is positioned on all four corners and not limited to the three corners where there is a base. If the verse had intended the latter ruling, it should have been phrased "to the base of the olah," referring specifically to the burnt offering where that limitation would apply. The Gemara resolves this difficulty by explaining the unique inclusion of the word "altar" in the verse: it teaches that when blood is spilled on the base, it must be spilled on the roof of the base (top flat surface) and not on the wall of the base. With this reading, the subsequent lines of the braita, where Rabbi Yishmael and Rabbi Akiva each say the law could have been derived by a kal va'chomer are reread including mention of the roof of the base. Rabbi Yishmael and Rabbi Akiva appear to assert the same logical argument using slightly different wording. Rav Ada bar Ahava and Rav Papa propose possible distinctions between their positions. Rav Ada argues that because Rabbi Akiva used more extended language about the remainder of the blood, that it "does not atone" and "does not come for atonement purposes," Rabbi Akiva must regard pouring the remainder as nonessential. Rabbi Yishmael, having said only "it doesn't atone," must hold that pouring the remainder is essential. Rav Papa rejects this reading, maintaining that no one posits an obligation to pour the remainder of the blood. He narrows the difference between Rabbi Yishmael and Rabbi Akiva to the specific case of the bird sin offering: whether mitzui, squeezing out the remainder of the blood and placing it directly on the wall of the altar while squeezing, is essential. Rav Papa understands Rabbi Yishmael to require mitzui, while Rabbi Akiva does not. A braita is then cited to support Rav Papa, showing that Rabbi Yishmael holds pouring the remainder is not essential. A difficulty is raised against Rav Papa's position, but the Gemara resolves it. Rami bar Hama introduces a tana who maintains that for sin offerings whose blood is placed on the inner altar, pouring the remainder of the blood on the base of the altar is essential; Rava, however, rejects this understanding of the braita and its conclusion. Rabbi Yochanan and Rabbi Yehoshua ben Levi dispute whether Rabbi Yehuda and Rabbi Akiva actually differ on the question of whether the remainder of the blood for inner sin offerings is essential.    

From where do we derive that the law regarding slaughtering of the burnt offering must be in the North, and that if not, it is disqualified? Since the sin offering is invalid if not slaughtered and its blood received in the North, and this requirement is derived from the burnt offering, a logical argument is made that the same requirement must apply to the burnt offering itself: how can a secondary prohibition be more strict than the primary prohibition? Three halakhot are brought to challenge this logic, but all difficulties are resolved. The Gemara then presents a second derivation for the requirement of the North for a burnt offering, based on the repetition of this requirement in Vayikra 4:29, following its initial mention in verse 24. The guilt offering must also be slaughtered and its blood collected in the North, and if not, it is disqualified. This is derived from two verses: Vayikra 7:2 and 14:13. A difficulty is raised regarding the use of the second verse, which relates to the sacrifices brought by the leper during the purification process, as that verse is needed for a different drasha. However, this challenge is resolved. The verse concerning the leper's sacrifices juxtaposes the guilt offering with both the burnt offering and the sin offering. If the law of the North for a guilt offering is derived from the burnt offering, why is the sin offering mentioned in that verse as well? Ravina explains that its inclusion teaches the principle that a law derived through juxtaposition cannot be used to teach that same law in another case through juxtaposition. Rava derives this principle from a different source: the bull sin offering of the kohen gadol, Vayikra 4:9–10. Can a law derived by juxtaposition be used to teach something through a gezeira shava? Initially, a proof is brought from the law regarding leprous clothing, which is derived from the law concerning a person with leprosy—originally derived through a gezeira shava. Rabbi Yochanan rejects this proof, arguing that the rules for deriving laws related to sacrificial items differ from those governing other laws. This distinction is demonstrated by the requirement of the North in the case of a guilt offering, which could have been derived from a gezeira shava from the sin offering, but was not - precisely for this reason.  

The halakha was decided according to the opinion of Rabbi Elazar in the name of Rabbi Shimon regarding pigul in the inner sin offerings. Rava (and some say Rav Yosef) wondered: Why is halacha being decided on a matter that is no longer relevant in our times? To this, Abaye responded: "Expound and receive reward." Is there a difference between offerings brought by non-Jews and those brought by Jews? Rabbi Shimon and Rabbi Yosi disagree on this matter. From which verses does Rabbi Shimon derive that certain laws do not apply to offerings brought by non-Jews? A baraita is brought which states that the tzitz (forehead plate of the High Priest) does not atone for offerings brought by non-Jews. Does this baraita align with the opinion of Rabbi Yosi as well? The prohibition against eating notar (leftover sacrificial meat) and tamei (impure items) applies even to offerings that do not have elements permitting consumption. What is the source for these halakhot?

Study Guide The Mishna enumerates items that cannot become pigul - meaning that even if the offering is rendered pigul due to improper intent during the sacrificial process, consuming these items does not incur the punishment of karet. This is because pigul applies only to items that are permitted through another action. For example, sacrificial meat becomes permitted only after the imurim (the parts of the sacrifice designated to be burned on the altar) are burned. Items that cannot become pigul include the kometz (a handful of meal offering), incense, meal offerings that are entirely burned, and others. Some items are subject to tannaitic debate, such as the libations that accompany sacrifices and the oil used in the ceremony for leper purification. The libations may be considered an integral part of the sacrifice, and therefore become pigul, just like the sacrifice itself, and the oil may be permitted only after the placement of the blood from the guilt offering, which would also then enable it to become pigul. Conversely, the Mishna lists items that can become pigul, as they are permitted through a specific action. In some sacrifices, like a burnt offering, the sprinkling of blood permits the meat to be burned on the altar; in others, like a sin offering, it permits the meat to be eaten by the kohanim. Rabbi Shimon maintains that pigul applies only to sacrifices offered on the outer altar. Ulla presents an ambiguous statement: he claims that if a kometz becomes pigul but is nevertheless burned on the altar, its pigul status is nullified. He supports this by arguing that if the kometz were not considered properly offered (due to its pigul status), it could not serve as a valid matir (an enabling act) for the remainder of the meal offering to become pigul. The Gemara explores Ulla’s intent. Initially, it suggests that one who eats a kometz rendered pigul is not punished by karet, but this is rejected as it is explicitly stated in the Mishna. The second suggestion is that, although ideally it should not be placed on the altar, if it is placed there, it should not be removed. This too is taught in a Mishna. The third suggestion is that if it were placed on the altar and fell off, it may be returned. However, this is also addressed in a Mishna, which rules that it should not be replaced. The Gemara ultimately concludes that Ulla refers to a case where the kometz fell off after the fire had begun to consume it. Although Ulla discusses this elsewhere, the teaching here emphasizes that this principle applies not only to a limb of an animal that is partially burned, where even the unburned portion is considered connected, but also to a kometz, where even if only part was burned, the entire portion is treated as a single unit and may be returned to the altar. Rabbi Yochanan is quoted as saying that pigul, notar, and impure items that were offered on the altar lose their forbidden status. Rav Chisda challenges the inclusion of impure items, arguing that the altar does not function like a mikveh to purify them. Rabbi Zeira responds by qualifying Rabbi Yochanan’s statement: it applies only when the item was already being consumed by the fire. Rabbi Yitzchak bar Bisna raises a difficulty from a braita that categorizes sacrificial meat as something whose impurity cannot be removed. This challenge is resolved in three distinct ways: by Rava, whose answer is rejected, and by Rav Papa and Ravina. The braita above is then cited in full. It includes four different drashot that aim to prove that the verse in Vayikra 7:20 refers to a person who was impure and ate sacrificial meat, rather than a pure person who ate meat that had become impure. One of the opinions presented is difficult to understand in terms of its derivation. Rav Yitzchak bar Avdimi is praised for offering a clear and insightful explanation, which is then brought and elaborated upon.
