Judges 7:16-21

Then he divided the three hundred men into three companies, and he put a trumpet into every man’s hand, with empty pitchers, and torches inside the pitchers. And he said to them, “Look at me and do likewise; watch, and when I come to the edge of the camp you shall do as I do: When I blow the trumpet, I and all who are with me, then you also blow the trumpets on every side of the whole camp, and say, ‘The sword of the LORD and of Gideon!’ ” So Gideon and the hundred men who were with him came to the outpost of the camp at the beginning of the middle watch, just as they had posted the watch; and they blew the trumpets and broke the pitchers that were in their hands. Then the three companies blew the trumpets and broke the pitchers—they held the torches in their left hands and the trumpets in their right hands for blowing—and they cried, “The sword of the LORD and of Gideon!” And every man stood in his place all around the camp; and the whole army ran and cried out and fled.
