Nehemiah 4:19-21

19And 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.

20In the place where you hear the sound of the trumpet, rally to us there. Our God will fight for us."

21So we labored at the work, and half of them held the spears from the break of dawn until the stars came out.
