Asarah be-Tevet is a Jewish fast day commemorating the beginning of the siege of Jerusalem by the Babylonians under King Nebuchadnezzar in 586 BCE that was a prelude to the destruction of the First Temple. The fast begins at first morning light on the 10th day of the Jewish month of Tevet. In Israel it is also a day to remember the victims of the Holocaust. However, Jews outside Israel observe Yom ha-Shoah as Holocaust Memorial Day. Discuss
