This was a wonderful evening.

Kindling the candles for the Festival of Lights, we bless G-d for performing miracles of freedom “in those days, in this time.” The commentators have long resolved the jarring use of apparently non-parallel prepositions: in those days, meaning long ago, but in this time, meaning at the present  point in the calendar year. For survivors…

This lecture turned out nicely, I think. If you haven’t heard Rabbi Ya’akov Trump, you’re in for a treat–skip past my part to about 26:00 for the good stuff. A century from now, people will say, “Trump, Trump…wasn’t there also a President by that name?”

YouTube sent me this gif for earning 10,000 subscribers. Really grateful that so many people enjoy Jewish history!

Really looking forward to this class. Thanks to Rabbi Ya’akov Trump for designing the flyer!

Aish Kodesh scholar Daniel Reiser holding a copy of my new book. Like Shakespeare holding a copy of one’s sonnets. Thank you!

The Piaseczno Rebbe, Rabbi Kalonymus Kalmish Shapira, refused to dignify the Nazis by naming them in his wartime sermons in the Warsaw Ghetto. In a rare moment of transparency, perhaps motivated by anguish over the suffering of his Hasidim, the Rebbe briefly suspended his euphemistic terminology with a curt third-person reference in his drashah on Parashat…

This was a huge amount of fun. If you are into Duties of the Heart, I think you will like this lecture! The video has a reference to Despacito by The Maccabeats, link provided below. Enjoy in good health!

I was stopped on my way in to davening this morning by someone who told me about the incredible shiur that Rabbi Efrem Goldberg of Boca Raton Synagogue gave on the Aish Kodesh this week. Here’s the excerpt–Rabbi Goldberg captures the agony of the Rebbe after the loss of his family in his typically powerful…

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…

  Hello everyone– My father’s yortsayt is coming up next week, and as in previous years I hope to begin another cycle of study of Maimonides on Teshuvah. Please visit the Maimonides on Teshuvah page page to learn more about how to participate in this free, Global Study of Maimonides program. Posts will also appear…

Their screams suffuse the entire universe, and yet the universe does not revert to primordial waters. It continues to exist as if completely unaffected, Heaven forbid.

It was about this time of year, five hundred years ago, when we were refugees seeking asylum in Portugal. Then they seized our children. If we don’t care about what has been happening to migrant families today—shame on us.

Hoping that Moshiach will arrive before July 22. If not, then this is a great time to listen to the insights of Rabbi Zev Goldberg on the traditional Kinot. I’ll provide historical context. We did this last year and it was really meaningful. Hopefully this is the last Tisha B’Av we will have to mark…
