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 13

13:19 And it came to pass, that when the gates of Jerusalem began to be dark before the sabbath, I commanded that the gates should be shut, and charged that they should not be opened till after the sabbath: and some of my servants set I at the gates, that there should no burden be brought in on the sabbath day.
