Nehemiah 2:11-13

So I went to Jerusalem and was there three days. Then I arose in the night, I and a few men with me. And I told no one what my God had put into my heart to do for Jerusalem. There was no animal with me but the one on which I rode. I went out by night by the Valley Gate to the Dragon Spring and to the Dung Gate, and I inspected the walls of Jerusalem that were broken down and its gates that had been destroyed by fire.
