Judges 7:16-22

And he divided the 300 men into three companies and put trumpets into the hands of all of them and empty jars, with torches inside the jars. And he said to them, “Look at me, and do likewise. When I come to the outskirts of the camp, do as I do. When I blow the trumpet, I and all who are with me, then blow the trumpets also on every side of all the camp and shout, ‘For the LORD and for Gideon.’” So Gideon and the hundred men who were with him came to the outskirts of the camp at the beginning of the middle watch, when they had just set the watch. And they blew the trumpets and smashed the jars that were in their hands. Then the three companies blew the trumpets and broke the jars. They held in their left hands the torches, and in their right hands the trumpets to blow. And they cried out, “A sword for the LORD and for Gideon!” Every man stood in his place around the camp, and all the army ran. They cried out and fled. When they blew the 300 trumpets, the LORD set every man’s sword against his comrade and against all the army. And the army fled as far as Beth-shittah toward Zererah, as far as the border of Abel-meholah, by Tabbath.
