Judges 7:16-18

16Dividing the three hundred men into three companies, he placed trumpets and empty jars in the hands of all of them, with torches inside. 17“Watch me,” he told them. “Follow my lead. When I get to the edge of the camp, do exactly as I do.

18When 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.’ ”
