Nehemiah 7:1-3

1 Now that the wall had been rebuilt, I had the doors set up, and the gatekeepers, the singers, and the Levites were put in charge of them.

2 Over Jerusalem I placed Hanani, my brother, and Hananiah, the commander of the citadel, who was more trustworthy and God-fearing than most.

3 I said to them: "The gates of Jerusalem are not to be opened until the sun is hot, and while the sun is still shining they shall shut and bar the doors. Appoint as sentinels the inhabitants of Jerusalem, some at their watch posts, and others in front of their own houses."
