Nehemiah 4:22-23

Amplified Bible

²² At that time I also said to the people, “Let each man with his servant spend the night inside Jerusalem so that they may serve as a guard for us at night and a laborer during the day.” ²³ So neither I, my brothers (relatives), my servants, nor the men of the guard who followed me, none of us took off our clothes; each took his weapon [even] to the water.
