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 7

7:3 And I said unto them, Let not the gates of Jerusalem be opened until the sun be hot; and while they stand by, let them shut the doors, and bar them: and appoint watches of the inhabitants of Jerusalem, every one in his watch, and every one to be over against his house.
