Nehemiah 2:12-16

And I got up in the night, I and a few men with me. I did not tell anyone what my God was putting into my mind to do for Jerusalem, and there was no animal with me except the animal on which I was riding.

So I went out at night by the Valley Gate in the direction of the Dragon’s Spring and on to the Dung Gate, and I was inspecting the walls of Jerusalem which were broken down and its gates which had been consumed by fire.

Then I passed on to the Fountain Gate and the King’s Pool, but there was no place for my mount to pass.

So I was going up at night by the ravine and inspecting the wall. Then I entered the Valley Gate again and returned.

However, the officials did not know where I had gone or what I was doing; nor had I as yet told the Jews, the priests, the nobles, the officials, or the rest who were doing the work.
