Nehemiah 2:12 I set out during the night with a few men. I had not told anyone what my God had put in my heart to do for Jerusalem. There were no mounts with me except the one I was riding on.

Nehemiah 2:14-15Then I moved on toward the Fountain Gate and the King's Pool, but there was not enough room for my mount to get through, so I went up the valley by night, examining the wall. Finally, I turn back and reentered through the Valley Gate.
