Nehemiah 4:18-21

And each of the builders had his sword strapped at his side while he built. The man who sounded the trumpet was beside me. And I said to the nobles and to the officials and to the rest of the people, “The work is great and widely spread, and we are separated on the wall, far from one another. In the place where you hear the sound of the trumpet, rally to us there. Our God will fight for us.” So we labored at the work, and half of them held the spears from the break of dawn until the stars came out.
