When the wall had been built and I had hung the doors, the gatekeepers, singers, and Levites were appointed.
References for Nehemiah 7:1
Then I put my brother Hanani and Hananiah the commander of the fortress in charge of Jerusalem. Hananiah was a faithful man who revered God more than many.
I said to them, "The gates of Jerusalem aren't to be opened during the hottest time of the day. While the gatekeepers are still on duty, have them shut and bar the doors. Also, appoint guards from among those who live in Jerusalem. Station some at their watch posts and some in front of their own houses."
