Aug 14, 2026

1:12:05

A man wrote to the Tzemach Tzedek, the third Rebbe of Chabad, about fears he couldn’t shake in matters of health and money. What came back was a long letter working through Torah sources to explain how fear takes hold and how to loosen its grip.

Jul 16, 2026

1:04:54

In 1612, Avraham Portaleone of Mantua published a landmark work of encyclopedic proportions covering all things Beis Hamikdash. Reading through four of his discussions, we meet a man working under far-from-ideal conditions.

HaRav Levi Yitzchak, In His Own Words: A Commemorative Study

Aug 4, 2026

1:00:05

HaRav Levi Yitzchak Schneerson spent his final years in exile in Kazakhstan, banished there by the Soviets for his work strengthening Jewish life across the Soviet Union. Soon after arriving there in 1940, he wrote a brief account of his imprisonment. It reads like no ordinary memoir: each line is a kabbalistic commentary on his own life, shaped by a deep belief in personal divine providence. Gathering to honor his yahrzeit on the twentieth of Av, we studied this account and worked to unpack its esoteric terms. It isn’t the easiest material to understand, but it does paint a vivid picture of this special leader and his worldview.

Isaiah 53 on Trial: The 1863 Vienna Case That Split Jewish Leadership

Jan 7, 2026

1:01:56

In the mid-1860s, a wave of rabbinic correspondence swept across central and eastern Europe as leading rabbis grappled with a vexing dilemma: how to respond to an antisemitic trial that touched directly on core points of Jewish theology. This case pitted antisemites against Jews, and within the Jewish community, enlightened progressives against traditionalists. Navigating this reality proved deeply contentious.

The Boy at the Bimah: A History of Bar Mitzvah Celebrations

May 14, 2026

1:12:38

The bar mitzvah ceremony didn’t always look the way it does today. In fact, for much of Jewish history, it barely looked like anything at all. In this episode, we investigate: When did a ceremony first appear? What did it look like? When did bar mitzvah boys start receiving an aliya? Leining? Leading davening? A derasha? We’ll trace its evolution among Ashkenazi Jews from the eleventh century through the seventeenth century.

The First Crusade: The 1096 Massacres and the Rituals They Created

May 6, 2026

1:06:42

In the spring of 1096, crusading armies swept through the Jewish communities of the Rhineland, leaving devastation in their wake. This class traces how those events gave rise to rituals of memory. In the community of Worms, fast days were proclaimed on the 23rd of Iyar and Rosh Chodesh Sivan, accompanied by elaborate mourning customs. We’ll see how in 1716, when Rosh Chodesh Sivan fell on a Friday, rabbinic authorities clashed over davening Maariv early that afternoon. We conclude by tracing the demise of these fast days while noting how other rituals, such as the recitation of Av HaRachamim, have endured to this day.

Did Rambam Actually Set Foot on Har Habayis?

Apr 23, 2026

1:03:21

In the late 1920s, a Jerusalem rabbi cited an obscure passage describing a certain Rabbi Moshe’s pilgrimage to the Holy Land, including what appeared to be a visit to the Temple Mount itself. He seized on it as proof that going there was halachically permitted. This sparked a fierce debate over the passage: Was it even credible? Who exactly was this Rabbi Moshe? Did the text actually refer to the Temple Mount? And if a great rabbi really did go there, what would that mean for us today? This is the second installment in a series about going up onto Har Habayis. Did Rambam Actually Set Foot on Har Habayis?

From Philadelphia to Newport: An Early American Teshuvah (1790)

Jul 1, 2026

1:14:24

In 1790, Moses Seixas of Newport, Rhode Island, and Manuel Josephson of Philadelphia corresponded, with Josephson composing what effectively amounts to a halachic teshuvah. Josephson raised concerns about the conduct of the Touro Synagogue in Newport, arguing that elements of the service were not being properly observed. The exchange provides an important window into the religious commitments and halachic awareness of early American Jews. It also stands as one of the earliest examples of a rabbinic-style teshuvah in the formative years of Jewish life in the United States.

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

28

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 discussion resurfaced a few years later after the Yom Kippur War, and then again in the wake of the famous Entebbe raid in 1976. The Hostage Dilemma: Part III (Israel, 1970–1976)

Wine: Blind Tastes, Price Controls, and the Most Regulated Wine Market You’ve Ever Seen

Jan 14, 2026

1:04:22

This class takes us inside the Jewish wine economy of earlier centuries. We will see communities enforcing price ceilings, outlawing seller collusion, and appointing assessors to protect community members from being overcharged. In some places, the system became so aggressively strict: monopoly-style selling rights, blind tastings, barrels sealed by wine assessors, community-owned measuring jugs, and stiff fines for anyone who tried to sell wine off the books.

Jews and Booze: Uncorking the Wine Debate During the Age of Prohibition

Feb 5, 2026

56:08

Today, we explore Jewish life during Prohibition, when the manufacture and sale of alcoholic beverages were banned in the United States. While the U.S. government granted religious exceptions for wine, both the Reform and Conservative movements distanced themselves from this loophole, endorsing the use of grape juice instead. One contemporary posek passionately rejected grape juice, and we’ll examine the central arguments that shaped this debate. As we’ll see, this issue became a defining point for Orthodox Judaism in the early 20th century. Jews and Booze: Uncorking the Wine Debate During the Age of Prohibition

Jun 4, 2026

This class traces the story of this uncertainty, primarily through the accounts of Jewish travelers who visited Eretz Yisrael and recorded what they saw and heard. This is the third installment in a series about going up onto Har Habayis. Is the Dome of the Rock Where the Mikdash Stood?
