Judges 7:11-21

11 and you shall hear what they say, and afterward your hands shall be strengthened to go down against the camp." Then he went down with Purah his servant to the outposts of the armed men that were in the camp.
12 And the Mid'ianites and the Amal'ekites and all the people of the East lay along the valley like locusts for multitude; and their camels were without number, as the sand which is upon the seashore for multitude.
13 When Gideon came, behold, a man was telling a dream to his comrade; and he said, "Behold, I dreamed a dream; and lo, a cake of barley bread tumbled into the camp of Mid'ian, and came to the tent, and struck it so that it fell, and turned it upside down, so that the tent lay flat."
14 And his comrade answered, "This is no other than the sword of Gideon the son of Jo'ash, a man of Israel; into his hand God has given Mid'ian and all the host."
15 When Gideon heard the telling of the dream and its interpretation, he worshiped; and he returned to the camp of Israel, and said, "Arise; for the LORD has given the host of Mid'ian into your hand."
16 And he divided the three hundred men into three companies, and put trumpets into the hands of all of them and empty jars, with torches inside the jars.
17 And he said to them, "Look at me, and do likewise; when I come to the outskirts of the camp, do as I do.
18 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.'"
19 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.
20 And the three companies blew the trumpets and broke the jars, holding in their left hands the torches, and in their right hands the trumpets to blow; and they cried, "A sword for the LORD and for Gideon!"
21 They stood every man in his place round about the camp, and all the army ran; they cried out and fled.
