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 4

4:22 Likewise at the same time said I unto the people, Let every one with his servant lodge within Jerusalem, that in the night they may be a guard to us, and labour on the day.
