Judges 7:16-21

Dividing the three hundred men into three companies, he placed trumpets and empty jars in the hands of all of them, with torches inside. “Watch me,” he told them. “Follow my lead. When I get to the edge of the camp, do exactly as I do. When I and all who are with me blow our trumpets, then from all around the camp blow yours and shout, ‘For the LORD and for Gideon.’ ” Gideon and the hundred men with him reached the edge of the camp at the beginning of the middle watch, just after they had changed the guard. They blew their trumpets and broke the jars that were in their hands. The three companies blew the trumpets and smashed the jars. Grasping the torches in their left hands and holding in their right hands the trumpets they were to blow, they shouted, “A sword for the LORD and for Gideon!” While each man held his position around the camp, all the Midianites ran, crying out as they fled.
