Judges 7:16-21

He divided the 300 men into three groups and gave each man a ram’s horn and a clay jar with a torch in it. Then he said to them, “Keep your eyes on me. When I come to the edge of the camp, do just as I do. As soon as I and those with me blow the rams’ horns, blow your horns, too, all around the entire camp, and shout, ‘For the LORD and for Gideon!’” It was just after midnight, after the changing of the guard, when Gideon and the 100 men with him reached the edge of the Midianite camp. Suddenly, they blew the rams’ horns and broke their clay jars. Then all three groups blew their horns and broke their jars. They held the blazing torches in their left hands and the horns in their right hands, and they all shouted, “A sword for the LORD and for Gideon!” Each man stood at his position around the camp and watched as all the Midianites rushed around in a panic, shouting as they ran to escape.
