Judges 7:19-22

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 round the camp, all the Midianites ran, crying out as they fled. When the three hundred trumpets sounded, the LORD caused the men throughout the camp to turn on each other with their swords. The army fled to Beth Shittah towards Zererah as far as the border of Abel Meholah near Tabbath.
