Ezra and Nehemiah are companion books, continuing the narration of Chronicles. Ezra details the first return of the Jews from their captivity in Babylon and the rebuilding of the Temple. Nehemiah gives an account of the rebuilding of Jerusalem and of the efforts to bring religious reform to the people.

Ezra 6

6:18 And they set the priests in their divisions, and the Levites in their courses, for the service of God, which is at Jerusalem; as it is written in the book of Moses.
