Judges 7:10-20

10 But if you are afraid to attack, go down to the camp with your servant Purah.
11 You will hear what they are saying, and then you will have the courage to attack." So Gideon and his servant Purah went down to the edge of the enemy camp.
12 The Midianites, the Amalekites, and the desert tribesmen were spread out in the valley like a swarm of locusts, and they had as many camels as there are grains of sand on the seashore.
13 When Gideon arrived, he heard a man telling a friend about a dream. He was saying, "I dreamed that a loaf of barley bread rolled into our camp and hit a tent. The tent collapsed and lay flat on the ground."
14 His friend replied, "It's the sword of the Israelite, Gideon son of Joash! It can't mean anything else! God has given him victory over Midian and our whole army!"
15 When Gideon heard about the man's dream and what it meant, he fell to his knees and worshiped the Lord. Then he went back to the Israelite camp and said, "Get up! The Lord is giving you victory over the Midianite army!"
16 He divided his three hundred men into three groups and gave each man a trumpet and a jar with a torch inside it.
17 He told them, "When I get to the edge of the camp, watch me, and do what I do.
18 When my group and I blow our trumpets, then you blow yours all around the camp and shout, "For the Lord and for Gideon!' "
19 Gideon and his one hundred men came to the edge of the camp a while before midnight, just after the guard had been changed. Then they blew the trumpets and broke the jars they were holding,
20 and the other two groups did the same. They all held the torches in their left hands, the trumpets in their right, and shouted, "A sword for the Lord and for Gideon!"
