Ta’anis In Teves

Now that Chanukah is over, we turn our attention to the somber day of Asarah B’Teves, a community-wide fast. Nevuchadnezar laid siege to Jerusalem on the tenth of Teves. That action culminated with the destruction of the first Beis HaMikdash. Therefore, Asarah B’Teves is one of the four fasts that commemorate the destruction of the Beis HaMikdash.
The Shulchan Aruch (580:2) notes that there is an ancient custom to fast on the eighth and ninth day of Teves as well. According to the Magen Avraham, the custom was instituted by the Sages of the Talmud. Of course, one may suggest that fasting three days in a row is simply a way to undo the damage from the doughnuts and latkes. However, there must be a real reason that is not necessarily a meme.
On the eighth day of Teves, King Ptolemy of Egypt assembled 72 Elders from the Sages of Israel. He put them into 72 separate rooms and did not reveal to them for what purpose he assembled them, so that they would not coordinate their responses. He entered and approached each and every one, and said to each of them: “Write for me a translation of the Torah of Moses, your teacher.” The Holy One, Blessed be He, placed wisdom in the heart of each and every one, and they all agreed to one common understanding. Not only did they all translate the text correctly, they all introduced the same changes into the translated text. It was miraculous that all the scholars independently made the same textual changes; nevertheless, the translation of the Torah into Greek is considered a sad day.
