Judges 7:18-19

7:18 When I and all who are with me blow our trumpets, you also blow your trumpets all around the camp. Then say, ‘For the Lord and for Gideon!’”

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.
