Hello friends and colleagues: Thank you for your consistent support and enthusiasm. I am delighted that so many people share my passion for Jewish history and thought, and consider it a rare privilege to share my research with you online and in person. I wish you all a blessed New Year of spiritual and material……

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…

July brought new tribulations upon the Jewish community as the Nazis, energized by their victories on the western front, formally eliminated virtually every non-governmental organization in the General Government. Charitable agencies, cultural leagues, and of course political groups were abolished, for both Jews and Poles. The ghetto population increased by tens of thousands as Jews……

My fourteen-year old son was the first to see the damage, and you gave me the precious opportunity to teach him some ancient truths about our long-standing relationship.

I had the pleasure of speaking with Zev Brenner of the famous Talkline last week; really pleased that there’s a lot of interest in the work of the Piaseczno Rebbe. The broadcast was aired last Saturday night and will be rebroadcast again tonight at 8pm EST on WSNR AM 620. Here’s the link to the……

Dean Boylan has been a mentor of mine since I joined Touro in 2006. Proud to be with him this morning at the Harvard Club as he receives the Education Update Outstanding Educator of the Year Award. With Dean Moshe Sokol of Lander College for Men and Executive Dean Robert Goldschmidt of the Mighty Avenue……

Is it possible for a person to be struck and not experience physical pain?

Meet Mr. Hunter Ross Loren, a precocious 13-year old who, together with his uncle Alan Loren, contacted me this week to discuss Jewish history. Hunter is an avid fan of Jewish history–especially, of all things, the Jews of the Polish-Lithuanian Commonwealth–and he is probably my youngest student online. As a follow-up to his Bar Mitzvah,……

Colleagues, I’m pleased to post a version of my new experimental course online for the public good. Please visit bit.ly/survivejewishhistory to access the course. The course is divided into twelve Existential Crises, covering historical eras from the Hellenistic to the Spanish Expulsion. Undergraduate students are required to complete several academic exercises to “survive” each level and……

Nonetheless, I proclaim my faith in God, that God is beyond limitation and nature, that God will save us. Let us go up and take it over, beyond reason and beyond logic.
