Nehemiah 2:13-15

And I went out by night through the Valley Gate to the Serpent Well and the Refuse Gate, and viewed the walls of Jerusalem which were broken down and its gates which were burned with fire. Then I went on to the Fountain Gate and to the King’s Pool, but there was no room for the animal under me to pass. So I went up in the night by the valley, and viewed the wall; then I turned back and entered by the Valley Gate, and so returned.
