Nehemiah 2:13-15

13So I went out at night through the Valley Gate toward the Well of the Serpent1 and the Dung Gate, and I inspected the walls of Jerusalem that had been broken down and the gates that had been destroyed by fire.

14Then I went on to the Fountain Gate and the King’s Pool, but there was no room for the animal under me to get through; 15so I went up the valley by night and inspected the wall. Then I headed back and reentered through the Valley Gate.
