Biblical Personalities: Ezra
“For the first day of the first month was the beginning of the ascent from Babylon, and on the first day of the fifth month he arrived in Jerusalem, by the benevolence of his Lord upon him (Ezra 7:9).”
“The people of the exile did so. Ezra the Kohen and the distinguished men who were the heads of the families, all of them renowned, separated themselves and convened on the first day of the tenth month to investigate the matter. They finished dealing with all the men who had taken in alien wives, by the first day of the first month (10:16-17)
On the first of Nisan, Ezra and his followers left Babylon for Jerusalem, and adjourned the convocation on the problem of intermarriage.
Ezra was worthy of bringing the Torah to Israel had Moshe nor preceded him (Sanhedrin 21b).
If Aaron had been alive, Ezra would have been greater than he in Ezra’s time (Kohelet Rabbah 1:4)
When Torah was forgotten by Israel, Ezra came up from Babylon and reestablished it (Succah 20a)
