Judges 7:19-20

7:19 Gideon took a hundred men to the edge of the camp at the beginning of the middle watch, just after they had changed the guards. They blew their trumpets and broke the jars they were carrying. 7:20 All three units blew their trumpets and broke their jars. They held the torches in their left hand and the trumpets in their right. Then they yelled, “A sword for the Lord and for Gideon!”
