Nehemiah 7:1-3

Now it came to pass, when the wall was built, and I had set up the doors, and the porters and the singers and the Levites were appointed, that I gave my brother Hanani, and Hananiah the governor of the castle, charge over Jerusalem; for he was a faithful man, and feared God above many. And I said unto them, Let not the gates of Jerusalem be opened until the sun be hot; and while they stand on guard, let them shut the doors, and bar ye them: and appoint watches of the inhabitants of Jerusalem, every one in his watch, and every one to be over against his house.
