Nehemiah 4:21-25

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, “Each man with his servant shall 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.
