Nehemiah 4:19-21

19I 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, 1rally 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.
