Judges 7:16-22

16He divided the three hundred men into three companies, and he put trumpets and empty pitchers into the hands of all of them, with torches inside the pitchers.

17And he said to them, “Look at me, then do likewise. When I come to the edge of the camp, do just as I do.

18When I and all who are with me blow the trumpet (ram’s horn), then all around the camp you also blow the trumpets and shout, ‘For the Lord and for Gideon!’ ”

19So Gideon and the hundred men who were with him came to the edge of the camp at the beginning of the middle watch, when the guards had just been changed, and they blew the trumpets and smashed the pitchers that were in their hands.

20When three companies blew the trumpets and broke the pitchers, they held the torches in their left hands, and the trumpets in their right hands to blow, and they shouted, “A sword for the Lord and for Gideon!”

21Then each stood in his place around the camp; and the entire [Midianite] army ran, crying out as they fled.

22When Gideon’s men blew the three hundred trumpets, the Lord set the sword of one [Midianite] against another even throughout the whole army; and the army fled as far as Beth-shittah toward Zererah, as far as the border of Abel-meholah, by Tabbath.
