Chasidut su Esdra 6:78

[It is written in the Talmud (Sanhedrin, 22b), “Mar Zutra, and some say Mar Ukva, said, the Torah was originally given to Israel in the Hebrew script and the holy Hebrew tongue, and it was again given to them in the days of Ezra in the Ashuritic script and in the Aramaic language. The Israelites finally chose to write the Torah in the holy Hebrew tongue and in the Ashuritic script.” It is clear from the verse in Ezra, chapter 6, that this choice was made on the third day of the month of Adar, for the book of Ezra is written in Aramaic up until chapter 6, verse 7, where it mentions that the Second Temple was completed on that very day, and then immediately from then on it continues only in Hebrew, except for fifteen verses in chapter 7.⁴⁸⁰These verses are the Aramaic text of the letter that king Aratakhshasta (Artaxerxes) gave to Ezra the Scribe (Ch. 7:11-26).]
