Nehemiah 7:2-4

2 that I commanded my brother Hanani, and Hananiah, the prince of the palace in Jerusalem (for he was as a man of truth and feared God above many);

3 and I said unto them, Do not let the gates of Jerusalem be opened until the sun is hot and even [with] the [guards] present, let them shut the doors and bar [them]. And appoint guards of the inhabitants of Jerusalem, each one in his watch and each one [to be] in front of his house.

4 Now the city [was] large and great, but there were few people in it, and the houses [were] not rebuilt.
