Nehemiah 4:16-23

16And from that day on, half of my servants carried on the work while half of them kept hold of the spears, the shields, the bows, and the coats of mail; and the captains were behind all the house of Judah. 17Those who were rebuilding the wall and those who carried burdens carried with one hand doing the work, and the other keeping hold of a weapon. 18As for the builders, each wore his sword strapped to his waist as he built, while 1the trumpeter stood near me. 19And I said to the nobles, the officials, and the rest of the people, “The work is great and extensive, and we are separated on the wall far from one another. 20At whatever place you hear the sound of the trumpet, assemble to us there. 2Our God will fight for us.”

21So we carried on the work with half of them holding spears from 3dawn until the stars 4appeared. 22At 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.” 23So neither I, my brothers, my servants, nor the men of the guard who followed me--none of us 5removed our clothes; each took his weapon even to the water.
