Nehemiah 7:2-3
7:2 I then put in charge over Jerusalem my brother Hanani and Hananiah the chief of the citadel, for he was a faithful man and feared God more than many do.
7:3 I said to them, “The gates of Jerusalem must not be opened in the early morning, until those who are standing guard close the doors and lock them. Position residents of Jerusalem as guards, some at their guard stations and some near their homes.”
