Then Yeshua the son of Yotzadak with his fellow cohanim, and Z’rubavel the son of Sh’alti’el with his kinsmen, organized rebuilding the altar of the God of Isra’el; so that they could offer burnt offerings on it, as is written in the Torah of Moshe the man of God.

this ‘Ezra went up from Bavel. He was a scribe, expert in the Torah of Moshe, which Adonai the God of Isra’el had given; and the king granted him everything he asked for, since the hand of Adonai his God was on him.

For ‘Ezra had set his heart on studying and practicing the Torah of Adonai and teaching Isra’el the laws and rulings.

Here is the letter that King Artach’shashta gave ‘Ezra the cohen and Torah-teacher, the student of matters relating to Adonai’s mitzvot and his laws for Isra’el:

We should make a covenant with our God to send away all these wives, along with their children, in obedience to the advice of Adonai and of those who tremble at the mitzvah of our God; let us act in accordance with the Torah.
