Nehemiah 4:20 in the King James Version
In what place therefore ye hear the sound of the trumpet, resort ye thither unto us: our God shall fight for us.
Context
19 I said to the nobles, and to the rulers and to the rest of the people, “The work is great and widely spread out, and we are separated on the wall, far from one another.
20 Wherever you hear the sound of the trumpet, rally there to us. Our God will fight for us.”
21 So we did the work. Half of the people held the spears from the rising of the morning until the stars appeared.
