Hello everyone! Please visit this site for my translation of Rabbi Moshe Cordovero’s classic Tomer Devorah (The Kabbalah of Forgiveness), a text often studied at precisely this time of year as we strive to improve our relationships with each other, with G-d, and with ourselves. The site also features a series of brief videos on each……

The Jews of the Danube Fall 2018 Lecture Series From its headwaters in Germany’s Black Forest to its final destination in the Black Sea, the Danube River flows through ten countries and over ten centuries of Jewish history. Great cities like Vienna and Budapest punctuate its course through East-Central Europe, the cradle of much of……

The invisible yet palpable echo of the crypto-Jewish tradition resonates through Portugal like the far side of a conversation faintly overheard in another person’s cell phone. A rush of sibilants or an exclamation of laughter confirms the reality of the distant interlocutor, even though we do not see her before us. The history of Portugal’s…

Join me in this global effort to prepare for Rosh Hashanah and Yom Kippur this year!

Hasidim of the Aish Kodesh should take note: this is likely the face of one of the murderers of Rabbi Kalonymus Kalmish Shapira hy”d. Jakiw Palij, a longtime resident of Queens, New York, was recently extradited to Germany for filing false information while immigrating to the United States after World War II. Palij served as……

Hello students, friends and colleagues– We still have a few hours before the onset of Shabbat and the possible arrival of Mashiach, but if we have to make it through another Tisha B’Av– If you are in Fort Lee, NJ Sunday morning or Crown Heights, Brooklyn Sunday afternoon, please join me for presentations on the……

Thanks to Ben Rothke for this kind review of Torah from the Years of Wrath in this week’s Jewish Link of New Jersey. I am very grateful to be a part of the community that values and spreads the teachings of the Piaseczno Rebbe; nice to see positive reviews! Keeping the Faith By Ben Rothke……

A brief overview of three categories of exceptional women who made the Talmud possible: supporters, enablers, and even teachers. Lecture delivered at the Young Israel of Lawrence-Cedarhurst on November 20, 2019.

Join us for a brief study of the lives and work of three very different women and their relationship to Talmud study.

Hello friends and colleagues in Toronto! I am delighted to be coming back to visit the old stomping grounds this coming Friday, eh? I hope some of you will be able to join me for a Shabbaton at the Aish Thornhill Community Shul, followed by the David Shemtow Memorial Holocaust Lecture on Sunday night. Please……
Brief visit to the Jewish community of Lyon, France. Considered the “capital of the resistance” during the Nazi occupation, the local population made much use of the so-called “traboule” passageways scattered throughout the old city.
Brief video on Daniel Bomberg and the early days of Talmudic printing in Venice. Lecture delivered at the Young Israel of Lawrence-Cedarhurst on November 13, 2019.
The Jews of Avignon are often known as the Pope’s Jews because they found shelter in the old city during the tumultuous 14th century under the Popes who briefly made their home in France rather than Italy.

This strange sculpture above the “Jewish Door” of the Saint Siffrein Cathedral continues to mystify visitors to Carpentras, France. What does it mean?

This was, for me personally, one of the highlights of my trip with Kosher River Cruises along the Rhone in the south of France. The President of the Carpentras synagogue, Mr. Meyer Benzecrit, graciously invited me to tour a section of the 14th century synagogue not yet open for public view. Excavations have revealed some……

Join me for three rather idiosyncratic, surprising lectures on the history of the Talmud and its transmission in the modern era. Three Wednesdays beginning November 13 at the Young Israel of Lawrence-Cedarhurst. Free and open to the community, no hard questions please.
The remarkable 14th century Mikvah in the basement of the Carpentras Synagogue. Fed by an artesian well, the waters continue to fill the space, although in the 18th century a more modern Mikvah with heated, filtered water was constructed one floor above.
Part two of a series of videos on the amazing medieval synagogue in Carpentras, in the Provence region of France. This video looks at the 18th century representation in the Baroque style, with some remarkable features.

Today was an absolutely fascinating day of discovery of Jewish history, exploring the 14th century synagogue in Carpentras, France: the second-oldest currently functioning synagogue in Europe. There are so many amazing things to view, so I’ve decided to break it up into several small videos, starting with this one, which looks at the entrance to……
