Nehemiah 4:21-23

So we carried on the work with half of them holding spears from dawn until the stars appeared. At that time I also said to the people, “Let each man with his servant spend the night within Jerusalem so that they may be a guard for us by night and a laborer by day.” So neither I, my brothers, my servants, nor the men of the guard who followed me, none of us removed our clothes, each took his weapon even to the water.
