In 1466, a young Jewish moneylender who grew up in Mantua but had spent three years in Bologna asked the duke for permission to return and lend again. The local Jewish community pulled strings to keep him out, treating him as an outsider who endangered everyone else’s livelihood. Rabbi Yosef Colon, the Maharik, ruled on the case, but others challenged his reasoning. The case brings us into the Talmudic discussions of unfair competition and the rights of newcomers. It also offers a close look at the economic realities of Jewish life in Renaissance Italy. Click here for the handout An Immigration Dispute: Mantua, 1466

A dangerously ill person needs to eat chicken on Shabbos, and nonkosher is available. Do you feed him the nonkosher chicken, or slaughter one properly and violate Shabbos? The Raavad’s answer survives in conflicting versions, and the Ramban left a blank space when reaching this topic. We’ll discuss how that happened, then follow the debate across two centuries. We’ll find that in France and Germany, the rishonim gave a reason the Spanish rabbis dismissed. That gap likely reveals how differently these communities felt about their gentile neighbors and their place in those societies. Click here for the handout Nauseous or Not?

How and when did the bris take the shape we recognize today? When did the sandek and kvatter enter the ceremony, and what do those words even mean? Today’s class traces the development of the bris in Ashkenaz between the twelfth and fifteenth centuries. We’ll explore the origins and context of its specialized terms, the deals people made to secure coveted honors, a controversial practice that the Maharam of Rothenburg protested for years without success, and the role women played in the ceremony. Along the way, we’ll examine a panel painted around 1300 that brings at least one version of the medieval bris into sharper focus. Click here for the handout What An Honor!

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 pre-print manuscripts of Tanya shed light on what the Alter Rebbe added to this seminal text at a later stage. Curiously, three of the most notable updates involve interpersonal relationships. This lecture was recorded live by Jewish Multimedia Library, a.k.a. JML, Melbourne Australia. Many additional recordings are available from their website: www.jml.org.au.

The Mishneh Torah printed in Venice in the 1570s was the product of a broad and deliberate program of censorship. Beyond removing the handful of references to the Christian founder, which we discussed in the prior class, the censors altered many other words and phrases. In some places, entire laws disappear; in others, the language is carefully adjusted to soften its force. In this class, we trace the principles that guided the censors and examine how their work left a lasting imprint on one of Judaism’s foundational texts. Censoring the Rambam: Part II

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.
