Nehemiah 2:13 (KJV)

So I came to Jerusalem, and was there three days.

And I arose in the night, I and some few men with me; neither told I any man what my God had put in my heart to do at Jerusalem: neither was there any beast with me, save the beast that I rode upon.

And I went out by night by the gate of the valley, even before the dragon well, and to the dung port, and viewed the walls of Jerusalem, which were broken down, and the gates thereof were consumed with fire.

Then I went on to the gate of the fountain, and to the king’s pool: but there was no place for the beast that was under me to pass.

Then went I up in the night by the brook, and viewed the wall, and turned back, and entered by the gate of the valley, and so returned.
