Nehemiah 4:22-23

4:22 At that time I instructed the people, “Let every man and his coworker spend the night in Jerusalem and let them be guards for us by night and workers by day. 4:23 We did not change clothes – not I, nor my relatives, nor my workers, nor the watchmen who were with me. Each had his weapon, even when getting a drink of water.

Nehemiah 13:14

13:14 Please remember me for this, O my God, and do not wipe out the kindness that I have done for the temple of my God and for its services!

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.”
