Nehemiah 2:13-16

So I went out at night by the Valley Gate in the direction of the Dragon’s Well and on to the Refuse Gate, inspecting the walls of Jerusalem which were broken down and its gates which were 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 went up at night by the ravine and inspected the wall. Then I entered the Valley Gate again and returned. The officials did not know where I had gone or what I had done; nor had I as yet told the Jews, the priests, the nobles, the officials or the rest who did the work.
