Judges 7:15-18

And so it was, when Gideon heard the telling of the dream and its interpretation, that he worshiped. He returned to the camp of Israel, and said, “Arise, for the LORD has delivered the camp of Midian into your hand.” 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!’ ”
