The fast of the 10th of the Hebrew month of Tevet, commemorating multiple tragic events in Jewish history including the beginning of the Babylonian siege of Jerusalem, will be observed on Tuesday by Jews around the world who will refrain from food and drink from daybreak until nightfall.
The fast, also known as Asarah B’Tevet, was originally established to commemorate the beginning of the siege of Jerusalem by the Babylonian emperor Nebuchadnezzar in 425 BCE. The siege was “the beginning of the end” and continued for 30 months until the walls of Jerusalem were breached, eventually leading to the destruction of the First Temple
on the 9th of the Hebrew month of Av in 586 BCE.
The fast of the 10th of Tevet eventually came to commemorate the translating of the Torah into Greek, considered one of the darkest days in Jewish history, and the passing of Ezra the Scribe, the leader who brought back the Jewish people to the Land of Israel at the end of the Babylonian exile.
Asara B’Tevet has also been accepted as a day to say Kaddish for those killed in the Holocaust
Asara B’Tevet is an unusual fast as it is the only fast that can fall on a Friday. There are two other minor fasts (meaning they last from daybreak to nightfall) observed by Jews: the Fast of Esther and the 17th of Tammuz. The two major fasts (meaning they last from nightfall to nightfall the next day) are the 9th of Av, when the Temple was destroyed, and Yom Kippur, the Day of Atonement.
Rabbi Moses ben Maimon, known as the Rambam or Maimonidies, wrote that fast days serve to remind us of “our wicked conduct and that of our ancestors, which resembles our present conduct and therefore brought these calamities upon them and upon us.” (Mishneh Torah, Fasts 5:1) The goal of the reminder is so that “we will repent and improve [our conduct],” according to Maimonidies.
