After the wall was finished and I had hung the doors in the gates, the gatekeepers, singers, and Levites were appointed.
I gave the responsibility of governing Jerusalem to my brother Hanani, along with Hananiah, the commander of the fortress, for he was a faithful man who feared God more than most.
I said to them, "Do not leave the gates open during the hottest part of the day. And while the gatekeepers are still on duty, have them shut and bar the doors. Appoint the residents of Jerusalem to act as guards, everyone on a regular watch. Some will serve at their regular posts and some in front of their own homes."
