Nehemiah 4:16, 23
And from that day on, half of my servants did the work while the other half held spears, shields, bows, and armor. The officers stationed themselves behind all the people of Judah / So neither I nor my brothers nor my servants nor the guards with me changed out of our clothes; each carried his weapon, even to go for water.
