Judges 7:8-12

So Gideon sent the rest of Israel to their homes. But he kept three hundred men and took the jars and the trumpets of those who left. Now the camp of Midian was in the valley below Gideon. That night the LORD said to Gideon, “Get up. Go down and attack the camp of the Midianites, because I will give them to you. But if you are afraid to go down, take your servant Purah with you. When you come to the camp of Midian, you will hear what they are saying. Then you will not be afraid to attack the camp.” So Gideon and his servant Purah went down to the edge of the enemy camp. The Midianites, the Amalekites, and all the peoples from the east were camped in that valley. There were so many of them they seemed like locusts. Their camels could not be counted because they were as many as the grains of sand on the seashore!
