Judges 7:14-24

14 His friend replied, "That can only be the sword of Gideon, son of Joash, from Israel. God is going to hand Midian and the whole camp over to him."
15 When Gideon heard the dream and its interpretation, he worshiped the LORD. Then he went back to the camp of Israel and said, "Attack! The LORD will hand Midian's camp over to you."
16 Gideon divided the 300 men into three companies. He gave them each rams' horns and jars with torches inside.
17 He said to them, "Watch me, and do what I do. When I come to the edge of the camp, do exactly as I do.
18 When I and those with me blow our rams' horns, then the rest of you around the camp do the same and shout, 'For the LORD and for Gideon!'"
19 Gideon and his 100 men came to the edge of the camp. It was the beginning of the midnight watch just at the change of the guards. They blew their rams' horns and smashed the jars they were holding in their hands.
20 The three companies also blew their rams' horns and broke their jars. They held the torches in their left hands and the rams' horns in their right hands so that they could blow them. They shouted, "A sword for the LORD and for Gideon!"
21 While each man kept his position around the camp, everyone in the Midianite camp began to run away, screaming as they fled.
22 The 300 men kept on blowing their rams' horns, and the LORD caused the whole camp of Midian to fight among themselves. They fled as far as Beth Shittah, toward Zererah, and as far as the bank of the stream at Abel Meholah near Tabbath.
23 The men of Israel were summoned from Naphtali, Asher, and all Manasseh to help pursue the troops of Midian.
24 Gideon also sent messengers to the whole mountain region of Ephraim with this message, "Go into battle against Midian. Capture the watering holes as far as Beth Barah and the Jordan River." All the men of Ephraim were also summoned to help. They captured the watering holes as far as Beth Barah and the Jordan River.
