Study Guide Eruvin 96 A week of learning is dedicated by Lisa Malik in memory of her father, David Malik, David ben Aharon Tzvi v’ Shaindel z”l on his first yahrzeit. The gemara brings two more possibilities to understand the debate between Tana Kama and Rabban Gamliel regarding how many pairs of tefillin can one wear at a time in order to bring them from the field into the city of Shabbat? According to the gemara's conclusion, at least Tana Kama holds that one wears tefillin on Shabbat and therefore the gemara tries to find who is the tana who holds that way? The gemara brings four suggestions. One of them is from a source regarding Michal daughter to Cushi (King Saul) who wore tefillin and the rabbis didn't protest. They assume it's because he held that one is obligated even on Shabbat and therefore it is not time bound, in which case women would be obligated. Despite the fact that the gemara rejects this, claiming that the rabbis didn't protest because women are allowed to opt in to commandments they are not commanded to do, in the end the gemara brings a proof from a different source that Rabbi Meir and Rabbi Yehuda in fact hold this position. An interesting question is raised regarding women opting in - is it forbidden to do a commandment one is not obligated to? Is it bal tosif (one cannot add to what the Torah commanded)? If one finds techlelet-dyed wool strips or thread, can one assume they were dyed for tzitzit. It depends in what form as one can assume that one wouldn't burden themselves to do thing sin a complicated manner just for clothing and therefore it must have been for tzitzit. Rava questions this from our mishna regarding one confusing an amulet and tefillin - would one bother to make an amulet like tefillin - it is compliccated to make it in that way!

Study Guide Eruvin 95 Do Rava and Abaye disagree about whether or not we can use imaginary walls created by a ceiling, pi tikra yored v'sotem (when there are no actual walls on any side), as Rav and Shmuel disagree? Does Rabbi Yosi in the mishna who disagrees with Rabbi Yehuda (that the beginning of Shabbat is the determining factor) permit in these cases or forbid? Do we hold like Rabbi Yehuda or Rabbi Yosi? Shmuel holds like Rabbi Yehuda, however the gemara questions that based on a different source. The mishna discusses cases of a bridge or a second floor built over the public domain - can one carry beneath it? On what basis would it be permitted? Can one fix (make an eruv) an alley that is open on two sides? On what basis could one permit? The tenth chapter begins with a discussion of tefillin found in a field. One is obligated to "save" them. How can one carry them on Shabbat - only if they wear them? Tana Kama and Rabban Gamliel disagree about whether one wears one pair or two at a time . What is the root of their debate? Does it connect with other basic debates such as, is one supposed to wear tefillin on Shabbat, do mitzvot need intent in order to fulfill them, is it forbidden due to bal tosif, adding to mitzvot, to wear two pairs at a time?

Pictures Study Guide Eruvin 94 Today’s daf is dedicated by Tzippy Wolkenfeld for a refuah shleima for Yakira Leeba bat Sara Gita, “our sweet brave girl.” If a courtyard wall is breached on Shabbat, do we say that since it was permitted at the onset of Shabbat to carry in each individual courtyard, the status remains the rest of Shabbat or not? If a courtyard is breached into the public domain, what is the status of that courtyard? Rabbi Eliezer says it is now considered a public domain and the rabbis call it a carmelit. The gemara struggles to understand how Rabbi Eliezer could view this space that belongs to the courtyard residents as a public domain and therefore narrows the debate to the space where the wall once stood that is not the subject of debate between the public and the courtyard residents. Or that the debate is really about the sides of the public domain that are sometimes used by the public and therefore also would extend to this case regarding the space near the border of the courtyard and the public domain. How does this work in with the wording of the mishna. The mishna states that if two walls of a courtyard or a house collapse on Shabbat, what is the status for that Shabbat. Two opinions are brought, however they both agree that regarding the next Shabbat, this is a breach. What size breach and why is it specifically two walls and not one? Due to this question, Rav and Shmuel each narrow the case of the mishna to a very specific type of breach in the corner. What do Rav and Shmuel disagree about regarding a ceiling dropping down and creating imaginary walls? In what size structure do they disagree?

Pictures Study Guide Eruvin 93 Abaye disagrees with those who said that the larger courtyard absorbs the inhabitants of the smaller courtyard as how can there be a barrier that connects rather than separates and therefore forbids (like planting near a vineyard? Various rabbis try to show Abaye that walls can connect/forbid in various situations but each time Abaye responds that the case isn't comparable. Rav Yehuda brings a case of encampments in large spaces shared like the courtyards discussed (walls seen from one side but not the other) - they are viewed as one whole unit if the outer ones can see walls when going into the inner one for the same logic as stated before that the larger courtyard absorbs the inhabitants of the smaller. Rav Chisda and Rav Mesharshia disagree about whether an embankment of 5 handbreadths can join with a wall of 5 and be considered a proper wall for laws of courtyards. A bratia is brought against Rav Chisda and three answers are brought. If the situation changes on Shabbat and a wall between courtyards is breached, does this prevent the inhabitants from carrying as they are now viewed as one whole, or can they rely on the fact that when Shabbat started, they were permitted and therefore also now. Can we learn the answer from our mishna?

Pictures Study Guide Eruvin 92 Today's daf is dedicated with gratitude to Hashem by Tina and Shalom Lamm to celebrate a new grandchild, Kedem Nachum Isaac, born to their children, Peninah and Eitan Kaplansky. The gemara questions Rabbi Yochanan's opinion regarding Rabbi Shimon based on a mishna. If there are two courtyards with a churva in between and one made an eruv and one didn't, can each of them carry to the churva or neither of them or both of them? The mishna discusses the case of a large roof opening up into a smaller one and the same for a courtyard. Why is it necessary to bring both cases? Some rabbis explained that the larger courtyard absorbs the residents of the smaller one but the smaller one does not absorb the larger one. They bring 5 different areas of halacha and explain the ramifications like giving a divorce document to a woman by placing it in the other courtyard or praying with nine people of the minyan in one space and one in the other, and other cases. Abaye disagrees with them on the basis that how can having a mechitza make the two areas seem closer? The rabbis try to disprove his logical argument.

Pictures Study Guide Eruvin 91 Today’s daf is dedicated in memory of Rabbi Lord Jonathan Sacks, HaRav Yaakov Zvi ben David Aryeh, zt”l who passed away yesterday. His teachings of Torah and human values will be shared and valued for generations. May his memory be blessed and may his family be comforted among the mourners of Zion. Rav Yehuda delves into the opinions of Rabbi Meir, the rabbis and Rabbi Shimon and explains what there would hold about carrying from the various areas to each other - like roof to courtyard to enclosure. The gemara brings a proof to support Rav's view of the rabbis that one can only carry four cubits on the roof if it is adjacent to another. Rav disagrees with Shmuel and Rabbi Yochanan regarding whether Rabbi Shimon allows carrying between areas even in a case where the courtyard residents made a eruv or only in a case where no eruv was made? The gemara brings questions against each of the opinions.

Pictures Study Guide Eruvin 89 Today's Daf is sponsored by Stacey Goodstein Ashtamker in loving Memory of her much-missed mother Arlene Goodstein, Enya Bat Chana v' Moshe's 5th yahrzeit. "My mother's presence is felt every day with all the wonderful things she taught us, her love of Judaism and Israel, and all the strength she gave us. She would be very proud of her daughter studying Talmud." Can one carry from roof to roof or enclosure to enclosure or courtyard to courtyard? There are three opinions. What is the background to these approaches? According to the rabbis, the roof follows the house and one cannot carry from one to the other. Rav and Shmuel debate whether according to the rabbis one could carry on the roof itself or only 4 cubits?  Their argument depends on using imaginary walls (gut asik mechitzta) - in what situations can we use that principle?

Pictures Study Guide Eruvin 88 Today's daf is sponsored by Rabbi Amy Bardack in memory of the 11 lives lost in the Pittsburgh synagogue shooting two years ago today. And our learning this week will be in memory of Eli Hoffman z"l who passed away yesterday.  Why did Rabbi Chanania ben Akavia permit those three things in Tiberias? Can one use the suspended walls coming out of the ledge only to draw water, but not to dump waste water? Or can it be used for both? If one steals a space from someone, does the original owner need to be part of the eruv or not? How does this make sense in light of the case in the mishna of the one who had a lower ledge and didn't make a suspended wall and uses (seemingly without permission) the wall of the upper ledge and thereby forbids the owner from using it unless they make a eruv together? The mishna and gemara discuss ways in which people can or cannot remove water from their house through the courtyard or the roof. What are the necessary requirements/what are the issues involved?

Pictures Study Guide Eruvin 86 Another week of our learning is dedicated for the refuah shleima of Eliahu Yonatan Ben Gittel Mira by Jeanne Klempner and Goody Weil.  We continue to pray for Eli's recovery and hope all of our learning will be a source of strength and to him and his family. According to Rabbi Yehuda, if the owner has some sort of hold on the property, even if someone else is living there, there is no need for an eruv. What type of hold is needed. in this context, a story is told about ben Bunios and his wealth and how the rabbis treated him with respect. Why is it important to respect the wealthy? If one leaves one's house for Shabbat, do they still need to be part of the eruv, and if not, they forbid the others from carrying? On what does it depend? Is there a difference between a Jew and a gentile? Rabbi Shimon says if one is going to one's daughter even in the same town, they do not forbid as clearly there are not going home. However, Rav infers that only one's daughter, but not one's son, due to the complicated nature of the relationship between a daughter-in-law and her in-laws. If there is a well between two courtyards, what is needed to allow each side to draw from their side of the well? Is the idea of viewing walls as imaginary walls that go do to the ground, allowed only where water is involved? Rabbi Sosi allows it for Sukka. Would he necessarily agree that it is allowed also for Shabbat. and if not, why in the case in Tzipori, in order to get a Torah to shul on Shabbat, they allowed it through walls that did not go all the way to the ground? The gemara suggests that maybe it was after his death and it was his son that permitted.

Pictures Study Guide Eruvin 85 Today's daf is dedicated by Gitta Neufeld in honor of the Hadran English Zoom Shiur. With deepest gratitude for your care and concern. "As I sat in a scary emergency room waiting room, unable to be at my husband's bedside because of COVID regulations, the shiur was my anchor and my rock. Baruch Hashem, we were able to come home - and I managed to complete the daf! הודו לה' כי טוב כי לעולם חסדו" A pit between two courtyards at a distance of four handbreadths from each courtyard - according to Shmuel, in order to permit drawing water, each would need to put up a small ledge as a reminder that if they were closer, each would forbid the other from carrying. Rav Yehuda allows even with a reed jutting out. Abaye says that Rav Yehuda was based on Shmuel and not Rav as Rav would not require anything here as access when one needs to get through airspace (of four handbreadths or more) would not forbid the other. The gemara tries to figure out from where Abaye knows Rav and Shmuel's opinions on this topic. After establishing that, the gemara questions both Rav and Shmuel. Where can one put eruv chatzerot? And what places are not allowed? What about shituf mevoot?

Pictures Study Guide Eruvin 84 Today's daf is dedicated by Debbie Ziering in loving memory of her mother, Evelyn Trotzky, Esther Chava bat Avraham z"l on her 23rd yahrtzeit. "A woman of quiet strength, grace and dignity, taken from us much too early." And for a refuah shleima of David ben Eidel. Rav and Shmuel disagree in a place that is accessible to one location by lowering down and the other by throwing - what is the law? To Rav, it is equally accessible to both and if they did not make a eruv with each other, meither can carry there. Shmuel holds that it is easier to access something by lowering than by throwing and therefore it is permitted for the one who it is accessible to by lowering. The gemara brings tannaitic sources, including our mishna, to try to prove who is right (two for each side) but each suggestion is rejected.

Study Guide Eruvin 83 This shiur is dedicated by the Greenstone cousins in honor of the birthday of our cousin, Lana Kerzner, a lawyer and advocate of social justice, a role model to the women and men of our family.  The loaf mentioned in the mishna is relevant for various measurements - for what? Why isn't the measurement for food impurities listed in the mishna as that is also based on the loaf. The gemara goes through various measurements and discusses where the size of an egg used in these measurements is exactly an egg or not. The sizes used in measurements got larger over time. What are the differences between them? On what size loaf is one obligated to separate challah? The mishna describes a situation with a porch and a courtyard that had mead an eruv separately as they are considered two separate spaces. If there is an item in the courtyard at a height of 10 handbreadths and close to the porch, it is considered part of the porch. Otherwise, it is considered part of the courtyard.

Pictures Study Guide Eruvin 77 Today’s daf (עז) is dedicated by Shelley and Jerry Gornish in memory of Oz Wilchek z"l, "our עז - our beloved and greatly missed grandson." How tall a wall is considered a separation between two courtyards that they would not be able to make an eruv together? If the wall is four handbreadths wide, each courtyard can access items at the top of the wall but cannot bring them down to their courtyard as the wall is a private domain in and of itself. What if the wall were less than four wide? Can one bring items from their courtyard to the wall as it is considered an exempt domain? What if the wall is ten high to one courtyard but lower for the other (as the ground of that one is higher)? The gemara brings various cases where one tries to lower the height of the wall, meaning to make it more accessible - either by lowering the wall itself or putting something on the floor to allow easier access. Does this mean that one can now use the wall as it is considered lower than ten? The gemara brings several different cases including ladders and other items.

Pictures Study Guide Eruvin 75 Today’s daf is dedicated by Rabbi Rebecca Einstein Schorr in honor of the first yahrtzeit of her grandfather Dov ben Yitzchak Yaakov HaLevi v'Rayzel z"l. "He would be thrilled to know that his death inspired me to take on the commitment to Daf Yomi." And by Sara Berelowitz in memory of her father Zvi ben Moshe z"l on his 12th yahrzeit. He always had a Soncino Gemara with him until the Shteinzaltz came out.  The mishna brings various permutations of two courtyards - an inner and an outer - what if one does an eruv and one does not, or both make their own eruv or they make one together and one person forgets, or there is only one person living in the courtyard. What is the law in each case? The gemara introduces the concept of "one who is allowed/not allowed to walk in their space, do they forbid/permit one who is in a different space" - if the space is space that they normally walk through (the inner as it walks through the outer). In other words - does the fact that the inner can walk through the outer forbid the outer space (if they don't make one eruv together) or not, and if so, under what circumstances? Who holds what (Rabbi Akiva and the rabbis) and are there two opinions or three? Rav Dimi brings and interpretation of the rabbis in the mishna in the name of Rabbi Yannai. But the gemara raises several questions until Ravin brought a different tradition. The gemara brings a bratia to support a statement and in that braita is another debate between Rabbi Akiva and the rabbis is brought up regarding an inner and outer courtyard. Raba bar Chanan and Abaye try to understand what is the root of the debate. The mishna permits a case of individuals - what about a case of 3 people living between the two courtyards?

"He would be thrilled to know that his death inspired me to take on the commitment to Daf Yomi." And by Sara Berelowitz in memory of her father Zvi ben Moshe z"l on his 12th yahrzeit. He always had a Soncino Gemara with him until the Shteinzaltz came out.  The mishna brings various permutations of two courtyards - an inner and an outer - what if one does an eruv and one does not, or both make their own eruv or they make one together and one person forgets, or there is only one person living in the courtyard. What is the law in each case? The gemara introduces the concept of "one who is allowed/not allowed to walk in their space, do they forbid/permit one who is in a different space" - if the space is space that they normally walk through (the inner as it walks through the outer). In other words - does the fact that the inner can walk through the outer forbid the outer space (if they don't make one eruv together) or not, and if so, under what circumstances? Who holds what (Rabbi Akiva and the rabbis) and are there two opinions or three? Rav Dimi brings and interpretation of the rabbis in the mishna in the name of Rabbi Yannai. But the gemara raises several questions until Ravin brought a different tradition. The gemara brings a bratia to support a statement and in that braita is another debate between Rabbi Akiva and the rabbis is brought up regarding an inner and outer courtyard. Raba bar Chanan and Abaye try to understand what is the root of the debate. The mishna permits a case of individuals - what about a case of 3 people living between the two courtyards?   

Pictures Study Guide Eruvin 74 Today’s daf is dedicated by Yehudit Robinson in honor of Sarah Robinson, Mishna and Talmud teacher at Manhattan Day School. And by Navah Levine in honor of Rachel Levy. With appreciation to a most enthusiastic and encouraging chevruta. "Thank you for helping to keep me on this Daf Yomi Derekh. Happy birthday." In order to permit carrying in an alley by using a side post or a cross beam, what is the minimum requirement of houses/courtyards in the alley? If this minimum is not there, the alley must be treated like a courtyard and either two side posts, one side post four handbreadths wide or a frame (tzurat hapetach) is needed. There are three opinions brought - by Rav, Shmuel and Rabbi Yochanan. The gemara first questions Rabbi Yochanan and also brings a different law of Rabbi Yochanan that matches his opinion here. Then they bring a difficulty for Shmuel - does he change his mind or not? Rav states a law regarding three houses that open to each other and only one opens directly to the alley. On the other side of the alley there is a gentile. One cannot make an eruv through the window of the inner houses. Why not? Would it be the same if they house of the Jew and the gentile opened up to a courtyard instead? Why would one think to distinguish between the cases?

Pictures Study Guide Eruvin 73 Today's daf is sponsored by Arlene Sevrinsky in memory of her father, Mordechai ben Avraham z"l on his yahrzeit. He taught us to love family, torah, learning and music. May his neshama have an aliyah. And by Hannah and Michael Piotrkowski in memory of Hannah's mother, Tsina Tova bat Leib Yisroel z"l on her 50th yahrzeit. She valued humility above all and is more loved and remembered as the years pass. What is the determining factor regarding eruv - where one sleeps or where one eats? If a man has a number of wives who each live in their own house, are they considered one unit for eruv or separate units? What about slaves? A student at his rabbi's house if he sleeps and eats there? Can one view a father and children or a rabbi and student as one unit for certain laws of eruvin and as separate units for others (in order to be lenient)? The mishna brings a number of cases regarding courtyards that open to each other and also to a shared alley. If they did only eruv of the courtyards or only shituf mevo'ot (sharing of alleyways), would it cover the other? What if there were both but one person/courtyard didn't join the eruv/shituf? The gemara struggles to understand the mishna as it seems to side on different sides of the Rabbi Meir/Rabbis debate regarding can one suffice with only one of the two. In the end, they conclude the mishna is all rabbi Meir and they explain the cases to match his opinion. Rav has an alternate version of the mishna - that the courtyards do not open to each other. Why does he not agree with the other version? Today's daf is sponsored by Arlene Sevrinsky in memory of her father, Mordechai ben Avraham z"l on his yahrzeit.

Pictures Study Guide Eruvin 72 Today's daf is dedicated for a refuah shleima for Rabbi Jonathan Sacks, Harav Yaakov Zvi ben Liba. And by Dr. Robin Zeiger and Professor Jonathan Ben-Ezra in honor of the wedding today of their daughter Nechama. "Nechama- you have no idea how much joy you bring to your father when you send him a page of Gemara you are learning in class and say, 'Abba- I remember learning this sugya with you.'" There is a debate how to understand the debate between rabbi Meir and the rabbis regarding one who either did joining of the alleyway or eruv of the courtyards - can one carry both between the courtyards and into the alleyway. Do they disagree only in the case where the joining of the alleyway was done with bread or only when it was done with wine? Do we hold like Rabbi Meir who is stringent? The mishna brings a debate between Beit Shamai and Beit Hillel regarding five people who live in a large room that is sectioned off into five unique spaces. Is this viewed as one for purposes of doing an eruv with other people in the courtyard or not (do they all give one portion or 5 separate ones)? The gemara first brings four different explanations regarding the debate. What type of separation is there between the sections? Do they disagree in the case of walls that do not have halachic status as walls (less than 120 handbreadths) or walls that are 10 handbreadths but do not reach the ceiling or walls that reach the ceiling? The gemara then brings two other explanations regarding the debate - is the debate about where the eruv is placed - in their room or in another house in the courtyard? If a family lives in a courtyard each with one's own separate space, do they join the eruv with others in the courtyard as one or as individuals? On what does it depend - where they sleep, where they eat? If one lives in someone else's property, what determines whether or not they need to join the eruv separately. Does it depend on what type of space is the person sleeping in - if it is a place normally used for living or not?

Study Guide Eruvin 71 This month's shiurim are sponsored by Tamara Katz in honor of the yahrzeits of her grandparents,  Sarah bat Chaya v'Tzvi Hirsh and Meir Leib ben Esther v'Harav Yehoshua Zelig z"l. The gemara brings a third source to question Rav Nachman’s opinion that one who inherits property on Shabbat can relinquish rights to the property. The gemara brings two answers. Ulla and Abaye disagree regarding relinquishing of rights on Shabbat. According, their opinions are shaped by the way they understand how the mechanism of relinquishing rights works – it is that the others are acquiring rights to the other’s property or is it that one is removing oneself from the property? If one has food in two separate partnerships with each courtyard that is next to him/her, can that serve as an eruv between them all? Or between some of them? There are three opinions. Does it depend on whether the partnerships are with the same food item? Does it need to all be in one utensil? Raba and Rav Yosef disagree about how to understand the root of the debate among the tannaim.

Study Guide Eruvin 70 This week's shiurim are sponsored by Rabbi Fredda Cohen in honor of her grandchildren, Violet Noa and Remy Meyer, and their great grandmother bubbie Paula Cohen, on the occasion of her 88th birthday. Yom Huledet Sameach. Today's shiur is dedicated by Gary Zeitlin in honor of the 5th yahrzeit of Susan Zeitlin z"l, a "kanai" for her family and for yiddishkeit. And by Oren and Rachel Seliger in memory of Rifka Esther bat Sara Gittel and Yeshaya Halevi z"l on her 10th yahrzeit. She was always engaged in learning and went to weekly shiurim. She would be proud of her children learning daf yomi.  The gemara continues to analyze the cases in the mishna of when relinquishing of rights is effective and when it is not. Abaye asks Rabba whether one needs to relinquish rights to everyone or is it enough to relinquish to one of the people who were part of the eruv? Rabba says one needs to do it to everyone. Abaye disagrees and questions Rabba from a braita and the gemara goes in depth into all the cases in the braita to explain them in general and in accordance with Rabba and Abaye. Rava asks Rav Nachman if one who inherits property on Shabbat can relinquish rights. Rav Nachman says yes, but adds that Shmuel disagrees. Rava brings several sources that seem to go against Rav Nachman. Two are brought in this daf and they are both resolved.

Pictures Study Guide Eruvin 67 Today's daf is dedicated in honor of Sam Cohen, starting a year of shlichut in Germany. Wishing you only the best and may we continue to strengthen each other and continue daf yomi. Also thank you to our amazing teacher who constantly makes complicated sugiout comprehensible and relatable. Ben and Shai. Rav Chisda asks Rav Sheshet two questions regarding situations that changed over Shabbat regarding gentiles (the gentile fenced in two houses that were previously separated by a public domain or the gentile died on Shabbat) would relinquishing of rights be allowed? A gentile who lives in the same alleyway as Jews but has a separate smaller entrance, can one assume the gentile prefers that entrance and is not considered part of the shared alleyway and therefore one would not need to rent the space from the gentile. On what does it depend? What are laws regarding a karpaf when it comes to carrying from the public domain into it, if it is larger than beit sa'atayim and considered a carmelit. Rabbi Yochanan says it is still viewed as a private domain for those purposes and one would be obligated by Torah law. A braita is brought to contradict and Rava and Rav Ashi bring two possible answers.

Pictures Study Guide Eruvin 66 Today's daf is dedicated in memory of Avraham Nachum ben Yitzchak Refael z"l on his yahrzeit. His dedication to Daf Yomi is an inspiration to his family, who continue in his footsteps. And by Debbie and Michael Schreiber in honor of our first grandchild Naomi Frumit to our children Yarden and Adam Schreiber of Jerusalem. May she flourish and grow and may her parents raise her to torah, chuppah and maasim tovim in a home that I know will be filled with love and simcha and Torah learning. Does Rabbi Yochanan really hold that one can make a rental arrangement on Shabbat with a gentile to allow carrying as happened in the situation at the inn? Didn't Rabbi Yochanan make a comparison between making an eruv (which can only be done on Shabbat) and renting from a gentile? The gemara explains the comparison as regarding other issues and not whether or not it can be done on Shabbat. Shmuel describes differences between cases where there are courtyards and one forbids or doesn't forbid the other and one can or cannot make an eruv with the other and concludes in which circumstances relinquishing rights would be permitted. One of his cases seems to be referring to the case in the inn with the gentile and Shmuel's conclusion contradicts Rabbi Yochanan who allowed relinquishing of rights in that case (after the gentile rented the space to them, they needed to relinquish their rights to one of the Jews as their eruv was nullified). The gemara delves more in depth into Shmuel's approach in some of the cases he mentioned which is based on the concept that relinquishing of rights from one courtyard to another is forbidden. Rava and Abaye disagree regarding the extent to which Shmuel said this? In which cases would be make exceptions?

Pictures Study Guide Eruvin 58 How does one measure the 2,000 cubits if the terrain is not flat? When does one span the space and one does one pierce it? What is the difference between them? From where do we derive that 50-cubit ropes are used? Why can't they be shorter or longer? What material are the ropes? For the red heifer and the Sotah, ropes were needed - of what material for each? How do we span a space? What if a canyon curves and spanning is not possible? Or if there is a wall? Why is a wall different than a fence? Rav Yehuda says in the name of Shmuel that piercing is only allowed if a plumb line doesn't drop straight down. If it does drop straight down, one would measure just the floor of the canyon. Is there a limit to the depth by which one can measure by spanning? If so, what is that limit? Rava limits spanning to a hill that has a slope of 10 handbreadths for 4 cubits, but if it is less of a slope, one measures the slope itself as if it were the ground. However, Rav Huna brings a different version of this statement that was said by Rava. How does one pierce? Piercing is only used for techumim and not for measuring in a case of a beheaded heifer, egla arufa, or a refuge city because they are from the Torah. The measuring should be done by an expert. If one measure unevenly -  we accept the wider measurement. Similarly, we accept testimony of a slave or maidservant regarding where the border is because the laws are rabbinic, one can be lenient.

Pictures Study Guide Eruvin 57 The gemara brings two more explanations regarding the Levite cities to explain how the empty space around the city comes out to a quarter - how is it measured and a quarter of what? Some questions are raised on some of the explanations. The mishna brings a debate between Rabbi Meir and the rabbis. According to Rabbi Meir, the 2,000 cubits of the techum are measured from 70.67 cubits outside the city. According to the rabbis, this is not the case - it is measured from the city borders but the 70.67 measurement is used to determine if two cities are considered as one for techum. There is a debate between emoraim whether it is a space of 70.67 per city or 70.67 all together. There is a situation where one city can combine two others that are on either side. What is that situation? The mishna begins to describe exactly how they did the measuring for the city.

When Mom created the Jewish Day School 40 years ago, would she have every thought that I would be learning Daf Yomi at age 47! And by Caroline Ofstein in honor of Yakir's bar mitzvah and for a refuah sheleima to Sheindel Chaya Bat Leah בתוך שאר חולי ישראל. Does a Torah scholar needs to live in a place that has vegetables? Are vegetables good for you or bad for you? One should not live in a place with uphills and downhills as it causes premature old age. When one squares off a round city for the purposes of techumim, how does one do it? Each side needs to correspond to the four directions - North, South, etc. The gemara gives advice about how to determine where the directions are - either based on the constellations or on the direction of the sun at different times of the year. How much extra does one get on the angles? A braita is quoted regarding the 1,000 cubits outside each of the Levite cities that are left wmpty as compared to the whole space around the city of 2,000 cubits - a ratio is brought of 1 to 4 and the gemara brings a number of explanations of how this ratio makes sense.
