    The Rebbe Spent Shabbos In Hiding (Parashat Yitro: January 27, 1940 in the Warsaw Ghetto)

    Searching for an escapee from the notorious Pawiak Prison, the Nazis arrested 255 Jewish leaders in the Warsaw Ghetto, holding them hostage and demanding that the community turn over the 21-year old resistance fighter Andrzej Kott. The rebel was not found. The Jewish hostages were eventually killed.  The Rebbe was forced to spend that Sabbath…

I just learned that there’s only 18 cabins left, so if you’re interested, please click the…

    Conference presentation at the “The 100th Anniversary of the Ukrainian Revolution and the Proclamation of Ukraine’s Independence,” held at the Ukrainian Institute, New York, Sunday, January 21.  My talk was inspired by a thought-provoking article in the Forward by Avital Chizik-Goldschmidt. A fascinating panel, which included Anna Procyk of CUNY, Serhy Yekelchyk of University of…

  • The Aish Kodesh On Beshalah (January 20, 1940 in the Warsaw Ghetto)

    The Aish Kodesh On Beshalah (January 20, 1940 in the Warsaw Ghetto)

    On Parashat Beshalah (January 20, 1940), a young rebel escaped from the notorious Pawiak Prison, located not far from the Piaseczno Bet Midrash. Andrzej Kott, the 21-year old leader of the military wing of a resistance movement called the Polish People’s Independence Action, was a child of assimilated Jewish parents who had converted to Christianity.…

    The Aish Kodesh and Rav Shagar (Parashat Bo 5702, January 24, 1942)

    The recent translation of the work of Rabbi Shimon Gershon Rosenberg (Rav Shagar, 1949-2007) promises to elevate his distinctive thought to a broader audience of readers (Faith Shattered and Restored: Judaism in the Postmodern Age), many of whom will resonate with Dr. Yitzchak Mandelbaum’s comment on his discovery of Rav Shagar: “I knew I had…

    The Deleted Drasha: Aish Kodesh on Parashat Bo 5700 (January 13, 1940)

    The Rebbe’s entry for Parashat Bo (January 13, 1940) is unusual. Recorded in the scribe’s careful hand, with minimal annotation, it has two bold diagonal lines drawn through the center of the text, indicating that the Rebbe rejected it altogether. A brief and uncharacteristic first-person comment is appended: “more of what we said I do…

    Rabbi Shlomo Katz on the Aish Kodesh

    I had chills listening to Rabbi Shlomo Katz review the Rebbe’s words on this week’s parashah. I am grateful for his kind words of praise for my recent book on the historical context of the Aish Kodesh, but to tell the truth, I hardly recognized my own words from the masterful treatment they received from…

  • The Aish Kodesh On Vaera 5702 (January 1942 in the Warsaw Ghetto)

    The Aish Kodesh On Vaera 5702 (January 1942 in the Warsaw Ghetto)

    Chaim Kaplan recorded the mood in the Warsaw Ghetto in January 1942:  The cold is so intense that my fingers are often too numb to hold a pen. There is no coal for heating and electricity is sporadic or nonexistent. In the oppressive dark and unbearable cold your mind stops functioning. Yet even in such…

    The Aish Kodesh on Vaera 5700 (Torah from the Warsaw Ghetto, January 1940)

    Five months into the Nazi occupation, the Jews of Warsaw struggled to keep up with the barrage of administrative decrees inflicted upon them by the Germans. When the Rebbe spoke on Parashat Vaera, which fell on January 6, 1940, the worst was still far off. The Nazis had replaced the leadership of the Jewish Council…
