Judges 7:15-18

When Gideon heard the telling of the dream and its interpretation, he dropped to his knees before God in prayer. Then he went back to the Israelite camp and said, “Get up and get going! GOD has just given us the Midianite army!” He divided the three hundred men into three companies. He gave each man a trumpet and an empty jar, with a torch in the jar. He said, “Watch me and do what I do. When I get to the edge of the camp, do exactly what I do. When I and those with me blow the trumpets, you also, all around the camp, blow your trumpets and shout, ‘For GOD and for Gideon!’”
