Nehemiah 7:1-4

Then it was, when the wall was built and I had hung the doors, when the gatekeepers, the singers, and the Levites had been appointed, that I gave the charge of Jerusalem to my brother Hanani, and Hananiah the leader of the citadel, for he was a faithful man and feared God more than many. And I said to them, “Do not let the gates of Jerusalem be opened until the sun is hot; and while they stand guard, let them shut and bar the doors; and appoint guards from among the inhabitants of Jerusalem, one at his watch station and another in front of his own house.” Now the city was large and spacious, but the people in it were few, and the houses were not rebuilt.
