Judges 7:19-21

19Gideon and the hundred men with him reached the outskirts of the camp at the beginning of the middle watch, just after the changing of the guard. They blew their horns and broke the jars that were in their hands. 20The three companies blew their horns and shattered their jars. Holding the torches in their left hands and the horns in their right hands, they shouted, “A sword for the LORD and for Gideon!”

21Each Israelite took his position around the camp, and the entire Midianite army fled, crying out as they ran.
