Classes by Mordechai Dinerman

In 1725, Rabbi Zalman Hena published Shaarei Tefilah and sparked controversy by calling for a complete stop to the use of taam ha'elyon—the unique system of trop traditionally used for reading the Aseres Hadibros. Rabbi Yaakov Emden wasn't having it and fired back forcefully in his Luach Eresh. This class unpacks their debate, the sources they cite, the Alter Rebbe's position, and what we know about the two competing systems of trop for reliving Matan Torah. Up High or Down Low? The Battle Over the Proper Trop for the Aseres Hadibros

Today, we're picking up where we left off in the story of chidush hasemicha. We'll look at what unfolded after Rabbi Levi ibn Chabib pushed back against Rabbi Yaakov Beirav's plan and how the controversy evolved in the decades that followed. We'll dive into Rabbi Yosef Caro's role in the debate and then turn to the remarkable mission in the 1830s, spearheaded by Rabbi Yisrael of Shklov, to find the Ten Lost Tribes in a bold attempt to revive semicha. The Great Semicha Controversy, Part II

After the Spanish Expulsion, a group of leading rabbis in Tzfas, led by Rabbi Yaakov Beirav, set out to revive semichah—the original form of judicial ordination that linked back to Moshe Rabbeinu. They planned to reestablish semichah through broad rabbinic consensus, but not everyone was on board. In Jerusalem, Rabbi Levi ibn Chabib strongly objected, raising serious questions about the halachic basis and the broader implications of the move. This class explores the halachic arguments, the historical backdrop, and the deeper motivations behind one of the boldest and most controversial rabbinic initiatives. The Great Semicha Controversy, 1538

There's a long and painful history of the Gemara being censored in Christian lands, but in 1728, a draconian form of censorship led to the publication of a heavily redacted Maseches Berachos. A fierce debate erupted within the Jewish community: was it better to print a mutilated Gemara, or not to print it at all? In this class, we explore the rabbinic voices on both sides, the arguments they advanced, and actual examples of the edits. It's a compelling glimpse into a community grappling with impossible choices under the weight of galus.

Sometime in the mid-1400s, Rabbi Shlomo Duran of Algiers penned a remarkable teshuvah directed at a group of conversos in Spain. These individuals, who had been forced to embrace Christianity since the 1391 persecutions, had managed to maintain their Jewish faith in secrecy. Their question centered on how they could refrain from the worst forms of chametz on Pesach without drawing the suspicion of the authorities—an endeavor fraught with challenges. This teshuvah touches on many halachic elements regarding chametz and reveals the Marranos' historical struggles in mid-fifteenth-century Spain. The Marranos' Secret Pesach

In the 1850s, a groundbreaking innovation was introduced in Galicia: machines to facilitate matzah production. What followed was a fierce and dramatic conflict that shook the Jewish world. Pamphlets were published on both sides, each defending its position with vigor, leading to intense debates over halachah, minhag, and economic policy. In this class, we jump into the heart of the controversy as it played out in the late 1850s—the first phase of this conflict—and then explore how later Chabad sources engaged with this issue. The Machine Matzah Controversy

The Alter Rebbe's unique script for safrus has a rich and winding history. It has been inked, shelved, revived, and debated—and everyone seems to have an opinion. So, what is the story behind this ksav? What sets it apart? Why do some embrace it wholeheartedly while others remain unsure? This class explores its historical trajectory, some of its writing nuances, and the ongoing conversation around its adoption.Links to images:Megilah of Rebbe Maharash in Aguch library:https://hebrewstam.blogspot.com/2013/03/blog-post_120.htmlMegilah attributed to Rebbe Maharash, Carlebach family:https://yeshivasstam.com/maharashTefillin of the Frierdiker Rebbe:https://hebrewstam.blogspot.com/2012/11/blog-post_19.html#comment-formTefillin attributed to Reb Reuven Sofer, Gurary family:https://hebrewstam.blogspot.com/2016/01/blog-post_21.htmlThe Story of the Alter Rebbe's Script

In the mid-12th century, the Almohads swept across North Africa and Spain, driven by a vision of a strictly unified Muslim society. For the Jewish communities under their rule, the choice was stark and unforgiving: convert, flee, or face death. Many outwardly embraced Islam while secretly maintaining their Jewish faith. A rabbi from afar denounced these covert Jews, insisting that their hidden devotion was meaningless. Rambam, however, fiercely rejected this view. In his Igeres Hashmad, he offered a scholarly and compassionate perspective, guiding his brethren through one of the most harrowing dilemmas in Jewish history. Rambam, the Almohads, and the Secret Jews

In the 1170s, the Jewish community in Yemen faced an existential crisis: a radical ruler forced them to convert to Islam, an apostate Jew spread anti-Jewish propaganda, and a self-declared Messiah sowed confusion. In response, the Rambam penned one of his most powerful letters, offering guidance and encouragement. As we approach the 44th Siyum HaRambam, we revisit this extraordinary letter, its historical context, and its enduring lessons. Rambam to the Rescue: His Legendary Letter to Yemen

In the 1470s, a series of outrageous blood libels were leveled against Jewish communities in the Germanic lands, including one in Regensburg. To secure their acquittal, the Jews of Regensburg needed an enormous sum of money—far beyond their means. The rabbis gathered in Nuremberg to strategize and ultimately turned to Rabbi Yosef Colon in Pavia with a pressing question: Could they obligate all Jewish communities in the Holy Roman Empire to contribute to helping the Jews in Regensburg? Rabbi Yosef Colon's response is a masterful work of Talmudic analysis and a sobering reflection on the historical realities of the time. The Regensburg Blood Libel

On the fifteenth of Shevat, 1348, in the city of Tudela, a man named Yosef performed kidushin with a young woman named Belita. What began as a seemingly ordinary wedding ceremony quickly became a shocking controversy. People who were present asked Belita whether she was truly consenting, and instead of her confirming, it was her father who spoke on her behalf. Further investigation revealed that Belita had previously stated her refusal to this marriage not once but twice, and, in fact, was already married to her uncle Avraham. To complicate matters, she was also engaged to a third man! On the eve of the Black Death sweeping through Europe, this tangled web of relationships turned into a halachic dilemma that ultimately reached the desk of Rabbi Yehudah, son of the Rosh. The Scandalous Marriage, 1348

Rabbi Shlomo ben Aderes, the legendary rabbi and leader of Barcelona, received countless questions during his tenure, many of which have been preserved to this day. In this class, we discuss six compelling cases of tax disputes. They reveal remarkable insights into the political and economic realities of the time, the dynamics within Jewish communities, and their interactions with the surrounding non-Jewish world. Taxes and Tensions: The Story of Jewish Tax Disputes in Medieval Spain

The book known as Yosifun, cherished in traditional Jewish circles, and the books of Josephus, preserved in Greek and Latin by non-Jewish hands, spark challenging questions about authorship, reliability, and reconstructing the Jewish past. This class explores how rabbis throughout the ages evaluated these works, their role on the Jewish bookshelf, and how to navigate the apparent discrepancies between their accounts and the teachings of chazal. Josephus

The Books of Maccabees tell the dramatic story of the Chanukah revolt and the heroism of the Jewish fighters. But who wrote these books, and why were they left off the Jewish bookshelf? We'll discuss the history of these texts, explore their reception among Jews throughout the ages, and probe the role they played—or didn't play—in shaping Jewish memory of the Chanukah story. Lost Lights of Chanukah: Exploring the Books of Maccabees

When a shipwreck in the 1500s left families wondering about the fate of their loved ones, rabbinic authorities debated whether the wives of the missing passengers could remarry. This centuries-old question resurfaced in 1912 with the famous sinking of the Titanic, reigniting the discussion of applying Halachah in tragic circumstances. The Titanic Question: The Halachic Dilemma of Men Lost at Sea

We kick things off with seven fascinating stories from the teshuvos of medieval Spain, where we discover shul seats being treated like real estate: bought, sold, inherited, mortgaged—and sometimes the center of heated disputes. Then, we shift our focus to Ashkenaz, where this phenomenon is noticeably absent, suggesting a very different set of attitudes and conventions about shul seats. Finally, we dive into how the poskim tackled some of these disputes, applying Halachah to their contemporary realities. Benches, Bargains, and Bickering: Shul Seating in the Middle Ages

In the 1630s, pioneering Jewish immigrants in Brazil asked when they should daven for rain, given that their seasons were reversed from those in Europe. Their question sparked a fascinating rabbinic debate that takes us back to a dramatic showdown in 14th-century Toledo, which continues to resonate today. Join us as we explore how Halachah navigates the balance between tradition and reality. The Climate Clash: Rain, Rabbis, and Rulings for the Southern Hemisphere 

In 1848, a man in Jerusalem on a journey to Judaism was devastated when told he must desecrate Shabbos because, despite undergoing a bris, he wasn't yet considered Jewish until completing the final step of immersion. His heartbreak ignited a halachic controversy, which we'll explore in this class. We'll uncover the identities of the key figures involved and delve into the moving story of a man willing to sacrifice everything for his newfound faith. The Warder Cresson Story

As we mark the 60th anniversary of the Lubavitcher Rebbe's sichos on Rashi, we will dive into how the Rebbe engaged with some of the earliest print editions and medieval manuscripts of Rashi's commentary. These unique editions often reveal variant readings of Rashi's words, each with its own story to tell. Through this journey, we'll gain a deeper appreciation for Rashi's foundational commentary—and the Rebbe's unique approach to understanding it.

Why has the Chabad community favored esrogim from Calabria? In this class, we'll explore the backstory, diving into the halachic debates about grafted esrogim and why they matter. We'll also take a closer look at the big discovery in 1955—when it turned out that even Calabria esrogim weren't completely immune to grafting—and what that meant moving forward. We'll unpack the history and the questions that still linger today. Rooted in Tradition: The Calabria Esrog Story

From the Cairo Geniza, we uncover an ancient Judeo-Arabic rabbinic essay offering unique insights into the history and development of the Jewish calendar, particularly the observance of the second day of yom tov outside the Land of Israel. As we delve deeper, this document emerges as part of a broader debate, addressing the Karaites' opposition to the two-day yom tov tradition. By comparing this text with Rambam's perspective, we'll gain a deeper understanding of this critical issue and a window into a pivotal moment in Jewish history. Lost in the Geniza: An Anonymous Teshuvah on the Two-Day Yom Tov Debate

In this class, we will analyze four beautiful piyutim that we chant on Rosh Hashanah and Yom Kippur, uncovering some structural oddities along the way. As we raise questions and examine older prints and medieval manuscripts, we'll uncover a story of mysterious censorship. While we'll piece together what happened, understanding why it happened will prove to be more challenging.   Links: Machzor, Lublin 1551 ⁠https://www.nli.org.il/en/books/NNL_ALEPH990011638640205171/NLI⁠     Bodleian Library, MS.

In the 1860s, European Jewish communities faced a unique halachic challenge: the arrival of new chicken breeds from distant lands. As these exotic fowl entered the marketplace, rabbis debated their kosher status, igniting an adjacent discussion on how and why the turkey became accepted as kosher. Fowl Play: The Great Turkey-Chicken Debate of the 19th Century

In the 1970s, a Chabad journal in Israel published a story about the Alter Rebbe reversing a halachic ruling based on a dream, sparking significant controversy. This incident opens the door to a fascinating exploration of a practice that was surprisingly common among Ashkenazic rabbis in the 12th and 13th centuries—using dreams to guide halachic decisions. Dreams of Revision: The Role of Dreams in Altering Halachic Rulings

In the 1830s, Rabbi Tzvi Hirsch Kalischer penned an extensive letter to one of the Rothschilds, seeking his support for an ambitious plan to reinstate the korbanos on the Temple Mount. The rabbi contended that awaiting Moshiach was neither necessary nor prudent. This proposal ignited a debate among his rabbinic contemporaries, a discourse that continued well into the 20th century. Today, this story invites us to delve into many of the laws involving the Beis Hamikdash, a particularly fitting endeavor during the Three Weeks. The Rabbi Who Wouldn't Wait: A Proposal to Reinstate the Korbanos

As we approach Gimmel Tammuz, marking the Rebbe's thirtieth Hilula, we're doing something different: a text-based class on an important talk by the Rebbe from Shabbos Korach 1988, a talk that captures a lot of the Rebbe's hashkafah. The aim is to find inspiration and wisdom in his words, which can be applied to our daily lives and shared with others. Unconditional Love: A Commemorative Study of a Talk by the Lubavitcher Rebbe

Rabbi Yisrael Lifshitz, a well-known commentator on the Mishnah, included a provocative legend about Moshe Rabbeinu in his writings, suggesting that Moshe naturally possessed negative character traits. Over the following decades, some rabbis strongly opposed this legend, arguing that its claims were baseless and defamed Moshe's revered image. In this class, we'll talk about the origins of this controversial story, look at both sides of the debate, and explore why this account struck a chord with many Chasidic authors. The Provocative Portrait: Unveiling the True Face of Moshe Rabbeinu

The Baal Shem Tov passed away on Shavuos in 1760, but the exact day of his passing and the time and manner of his burial have long been subjects of controversy and mystery. In this class, we explore this subject by learning about two major debates regarding yom tov burials that emerged during the Middle Ages. Through this journey, we aim to deepen our appreciation for the laws and values related to yom tov observance and the proper dignity afforded to those who have passed away. Yom Tov Burial: The Talmud, the Rishonim, and the Baal Shem Tov

How does a halachic mind interpret the harrowing events at Masada, where Jewish rebels chose death at their own hands over surrender? In this class, we delve into this question, exploring not only the tragic case at Masada but also similar ethical dilemmas faced by Jews during the Middle Ages when confronted with forced conversions under Christian rule. The complexities of these historic moments offer deep insights into the moral and spiritual struggles that have shaped Jewish resilience and identity. The Masada Martyrs: Halachic Perspectives on History's Hardest Choices

Throughout history, Jewish communities have thrived in diverse locales, each presenting unique agricultural schedules. While adhering to the prohibition against eating chadash proved feasible in some regions, in others, it posed significant obstacles to daily life. This class delves into the strategies employed by the Ashkenazi rishonim and the legendary Acharonim of Poland, exploring five approaches to justify non-compliance, particularly in circumstances where adherence would be exceptionally challenging. Grain Matters: Navigating the Chadash Predicament Across the Centuries

In 1759, a clandestine faction of Shabetai Tzvi's followers in Poland committed a startling act: they collectively converted to Christianity while simultaneously accusing Jews of the age-old fabrication of using blood in matzah production. Despite the longstanding existence of the blood libel, this marked the first instance where the accusation was made by citing and distorting Talmudic and halachic sources. In this class, we examine the specific passages they employed and learn the response of the Jewish leadership during that era. As Ber of Bolochov, the chronicler of this event, emphasized, recording this narrative was essential to ensure that future generations would understand the suffering and trials of their ancestors and how it was notably worse when it emanated from within the Jewish community. The Frankist Blood Libel

The Kittsee Haggadah The library of Agudas Chasidei Chabad houses a remarkable manuscript crafted in 1760 by the talented scribe and artist Chaim ben Asher Anshel of Kittsee, near present-day Bratislava. We'll trace the journey of this Haggadah from its creation to its acquisition by the Frierdiker Rebbe. Opening this manuscript, we'll examine its layout, artwork, nusach, and style of nikud, seeking to uncover the influences that shaped Chaim ben Asher's masterpiece through a comparative analysis with other Haggadahs of that period.

In the year 1550, two non-Jewish printers published competing editions of Rambam's Mishneh Torah. One of them partnered with an esteemed rabbi from Padua, who, in his quest for support, turned to Rabbi Moshe Isserlis. Rama's response along with a careful examination of the printed volumes unveil the details of this dispute. Rama's scholarly answer also sheds light on various areas of commercial Halachah as well as the Noahide laws. The Printers' Clash: The Battle Over Rambam's Mishneh Torah, Venice 1550

There have been tragic instances where Jewish women felt compelled to take drastic measures to save the lives of their fellow Jews. When rabbis were presented with these real-life cases, they turned to the story of Esther for inspiration and guidance. Seduction and Sacrifice: From the Purim Story to the Responsa Literature

Today, we explore enigmatic Megilahs, where the absence of the text eclipses the written word. We'll learn that this peculiar phenomenon is just a fragment of a larger tendency reflected in the Geniza to produce incomplete texts. We shall unravel the motivations behind this practice, reminding us of the formidable challenges in reproducing sacred texts by scribal hand.   Links: First Megilah image: https://cudl.lib.cam.ac.uk/view/MS-TS-AS-00044-00005/1 Second Megilah image: https://cudl.lib.cam.ac.uk/view/MS-TS-NS-00286-00043/1 Third Megilah image: https://cudl.lib.cam.ac.uk/view/MS-TS-NS-00286-00043/1 First Chumash image https://cudl.lib.cam.ac.uk/view/MS-TS-A-00043-00004/2 Second Chumash image: https://cudl.lib.cam.ac.uk/view/MS-TS-A-00043-00013/2 First Tehilim image: https://cudl.lib.cam.ac.uk/view/MS-TS-NS-00281-00131/2 Second Tehilim image: https://cudl.lib.cam.ac.uk/view/MS-TS-AS-00039-00186/2 Final Megilah Image https://cudl.lib.cam.ac.uk/view/MS-TS-AS-00041-00207/1 Scrolls, Scribes, and Shortcuts: An Incomplete Megilah in the Cairo Geniza

Tunisian Jews used to refer to Tanach with a very odd name, and few understood why. Fortunately, illuminated medieval Jewish manuscripts can help solve this mystery. They bring us back to the 14th century, where we find Rabbi Yitzchak ben Moshe Halevi fervently contending that there has been a neglect of studying Tanach and that this is akin to abandoning the sacred Beis Hamikdash.

In this episode, we explore the intriguing narrative of a Jew named Shlomo, also known as Fillipo, who found himself ensnared by the Inquisition in Venice during the 1580s. Raised as a Christian in Portugal during a period when Jews were prohibited from residing there, Shlomo's journey took a profound turn when he embraced Judaism in Venice, a choice that carried substantial risks. His captivating story can be learned through the archives of the Venetian Inquisition but also through two rabbinic responsa. In the Dungeons of the Inquisition

We examine the tale of the heartless chicken that ignited lively discussion among rabbinic authorities in the year 1709. We introduce the pivotal figures in this intriguing narrative, examine the framing of the question, analyze the diverse range of answers proposed, and learn about the captivating research endeavors undertaken by these rabbis in their quest for a definitive solution. This engaging study about the interplay between science and tradition offers unique insights into the intellectual landscape of the time. The Heartless Chicken

In 1158, Rabbi Avraham ibn Ezra found himself disturbed by a provocative dream, which ultimately inspired him to author a treatise concerning the proper start time of the halachic day—evening. One possibility is that this work was a polemical discourse aimed at Rashbam's Torah commentary. This prompts us to delve into the story of this commentary, examining some of the controversial passages that have sparked confusion throughout the ages. Ultimately, we emerge from this exploration with an empowering revelation: the fact that the halachic day commences at nightfall teaches us about becoming resilient in times of crisis. The Puzzle of Peshat: Rashbam's Controversial Commentary

Kol Nidrei has been associated with controversy since its inception, and we're here to delve deep into its intriguing story.
