The Hostage Dilemma: Part II

Nov 25, 2025

1:07:27

Today, we’re returning to the topic of hostages in Jewish history. Last time, we spent most of our attention on the exceptions to the rule. This time, we’re looking at cases where the Mishnah’s ban on overpaying played at least a partial role in shaping actual halachic decisions and communal policy. And yet, as we will see, the overarching conclusion that we reached in the prior class will hold: overpaying often occurred. And it’s all a step closer to discussing this dilemma in the contemporary context, which we will do in an upcoming class. The Hostage Dilemma: Part II

The Hostage Dilemma: Part I

Nov 17, 2025

1:10:10

This class takes up one of the most challenging moral questions in Halachah: how far should we go to redeem captives? We’ll look at how this issue unfolded in Jewish communities around the world during the fifteenth and sixteenth centuries—what actually happened, and how the poskim grappled with the Mishnah’s rule against paying more than market value. In a future class, we’ll revisit this topic in the modern context of Israel and its ongoing struggle against terrorism. The Hostage Dilemma: Part I

Oct 24, 2025

1:15:29

In this class, we’ll trace how the sale of mitzvos in shul began, why it caught on, and how it spread across the Jewish world. We’ll look at halachic debates about selling on Shabbos and Yom Tov and at the fiery disputes that erupted over bidding rights, auction miscommunications, and the occasional auctioneer mischief. We’ll also hear from the voices who opposed the practice and what their protests reveal about their communities and times. Bidding Wars: Inside the History of Selling Shul Honors

The Saga of Shul Shmoozing: A Historical Look at Talking in Shul Across the Centuries

Sep 11, 2025

1:00:31

Jews have been talking in shul for centuries, and rabbis and communities have tried countless ways to stop it. From twelfth-century Cairo to the Lower East Side in the early 1900s, this struggle has played out across Jewish communities worldwide. This class offers a light yet thoughtful examination of the history of “shul chatter” and how Jews have navigated it through the ages.

The Cantonist Crisis

Aug 22, 2025

1:23:33

In 1827, Czar Nicholas I decreed that Jewish boys and young men be conscripted into the Russian army, a policy that shook Jewish life in Russia to its core. Communities debated and attempted various strategies to confront this crisis, and in that context, the Tzemach Tzedek was asked whether a particular approach was permissible. In this class, we’ll explore the historical backdrop, unpack the Tzemach Tzedek’s responsum, and work together to understand its meaning. The Cantonist Crisis

Jul 30, 2025

1:05:49

In this class, we will delve into the architectural anomaly of the “four halls” described in Yosifun’s account of the Beis HaMikdash. This description contradicts the sources in Chazal, and as we will discover, there is a fascinating history behind how this peculiar design came to be.

The Draft Dilemma: The Chilling Reality of Jews Deciding Who Gets Drafted

Jul 4, 2025

1:19:35

What do you do when the government demands soldiers and says you have to choose who goes? That’s exactly what Jewish communities in the late 1700s faced when the Austrian-Hungarian Empire started drafting Jews into the army. In this class, we look at how the rabbanim responded to this impossible situation and uncover the moral struggle beneath their rulings.

The Dilemma of Handing Over One to Save Many

Jun 20, 2025

1:09:12

Can a Jewish community surrender one of its own to save the many? This class explores three cases from the 1600s and 1700s, where this wrenching question was brought before leading rabbanim. We’ll learn about the details of each case, the rulings the rabbis issued, and the Talmudic sources that shaped their decisions. The Dilemma of Handing Over One to Save Many

10

The Rabbi Who Couldn’t Quit Gambling

Jun 10, 2025

1:07:01

Today, we’ll examine the debate in Venice in 1630 over a communal ban against gambling. Local leaders moved to outlaw games of chance, but Rabbi Yehuda Aryeh Modena pushed back, arguing that the community had no right to restrict a Jew’s freedom in this area. Along the way, we examine the authorship of an anonymous 1595 dialogue on gambling, offering an overview of the halachic arguments and a window into public attitudes about his subject at that time. The story comes full circle as we turn to explore Rabbi Modena’s unique and candid autobiography. The Rabbi Who Couldn’t Quit Gambling

11

Up High or Down Low? The Battle Over the Proper Trop for the Aseres Hadibros

May 28, 2025

1:13:41

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

12

The Great Semicha Controversy, Part II

May 20, 2025

1:14:56

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, 1538

May 13, 2025

1:13:59

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

The Doctored Talmud: Prague, 1728

May 6, 2025

1:21:15

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.

The Marranos’ Secret Pesach

Apr 2, 2025

1:11:27

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

The Machine Matzah Controversy

Apr 2, 2025

1:19:21

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.

Rambam, the Almohads, and the Secret Jews

Mar 13, 2025

1:09:09

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 to the Rescue: His Legendary Letter to Yemen

Feb 28, 2025

1:03:31

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

The Regensburg Blood Libel

Feb 21, 2025

1:06:22

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

The Scandalous Marriage, 1348

Jan 24, 2025

1:04:42

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.

Nov 29, 2024

1:01:54

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

Jun 18, 2024

1:12:19

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 Frankist Blood Libel

May 8, 2024

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.

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.
