Holidays10 Tevet · Dawn to nightfall
The day the Babylonian siege of Jerusalem began: a fast of mourning, and of the hope of return.


"In the ninth year, in the tenth month, on the tenth of the month, Nebuchadnezzar king of Babylon came against Jerusalem with all his army" (2 Kings 25:1). The siege that began that day ended two and a half years later with the destruction of the First Temple.
The prophet Zechariah calls it "the fast of the tenth month" (8:19), and promises that these fasts will one day become days of joy and gladness.
The Selichot of the day also remember the 8th of Tevet, when the Torah was translated into Greek, and the 9th, the passing of Ezra the Scribe. In Israel, the Chief Rabbinate set it as a day of Kaddish for victims of the Holocaust whose day of death is not known.
