Judges 7:19-21

19So Gideon, and the hundred men that were with him, came unto the outermost part of the camp in the beginning of the middle watch, when they had but newly set the watch: and they blew the trumpets, and brake in pieces the pitchers that were in their hands.

20And the three companies blew the trumpets, and brake the pitchers, and held the torches in their left hands, and the trumpets in their right hands to blow withal: and they cried, The sword of the LORD and of Gideon.

21And they stood every man in his place round about the camp: and all the host ran; and they shouted, and put them to flight.
