Judges 7:13-14, 16-20

And when Gideon was come, behold, there was a man telling a dream unto his fellow; and he said, Behold, I dreamed a dream; and, lo, a cake of barley bread tumbled into the camp of Midian, and came unto the tent, and smote it so that it fell, and turned it upside down, so that the tent lay flat. And his fellow answered and said, This is nothing else save the sword of Gideon the son of Joash, a man of Israel: into his hand God hath delivered Midian, and all the host.

And he divided the three hundred men into three companies, and he put into the hands of all of them trumpets, and empty pitchers, with torches within the pitchers. And he said unto them, Look on me, and do likewise: and, behold, when I come to the outermost part of the camp, it shall be that, as I do, so shall ye do. When I blow the trumpet, I and all that are with me, then blow ye the trumpets also on every side of all the camp, and say, For Jehovah and for Gideon. So 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. And 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 wherewith to blow; and they cried, The sword of Jehovah and of Gideon.
