71 Now when the building of the wall was complete and I had put up the doors, and the door-keepers and the music-makers and the Levites had been given their places, 2 I made my brother Hanani, and Hananiah, the ruler of the tower, responsible for the government of Jerusalem: for he was a man of good faith, fearing God more than most. 3 And I said to them, Do not let the doors of Jerusalem be open till the sun is high; and while the watchmen are in their places, let the doors be shut and locked: and let the people of Jerusalem be put on watch, every one in his watch, opposite his house. 4 Now the town was wide and great: but the people in it were only a small number, and the houses had not been put up.

Nehemiah, having finished the wall, returned to the Persian court, and came to Jerusalem again with a new commission. The public safety depends on every one's care to guard himself and his family against sin.
