Asarah B'Tevet (Tevet 10)

Jerusalem Under Siege

On Asarah B'Tevet, the 10th day of the Jewish month of Tevet, in the year 3336 from Creation (425 BCE), the armies of the Babylonian emperor Nebuchadnezzar laid siege to Jerusalem. Asarah B'Tevet (this year, December 14, 2021) is observed as a day of fasting, mourning and repentance.

On Asarah B'Tevet, the 10th day of the Jewish month of Tevet, in the year 3336 from Creation (425 BCE), the armies of the Babylonian emperor Nebuchadnezzar laid siege to Jerusalem. Thirty months later—on 9 Tammuz 3338—the city walls were breached, and on 9 Av of that year the Holy Temple was destroyed. The Jewish people were exiled to Babylonia for 70 years.

Asarah B'Tevet (this year, December 14, 2021) is observed as a day of fasting, mourning and repentance. We refrain from food and drink from daybreak to nightfall, and add selichot and other special supplements to our prayers. The fast ends at nightfall or as soon as you see three medium sized stars in the sky (breaking the fast after Kiddush, when the fast is on Friday).
