Ezra and Nehemiah are companion books, continuing the narration of Chronicles. Sezra 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 reforms to the people.

Nehemiah 9

9:38 And because of all this we make a sure covenant, and write it; and our princes, Levites, and priests, seal unto it.
