Judges 7:10-12

But if you are afraid to engage them, first go down to the camp with your servant Purah. Listen to what they are saying, and then you will be brave and have the courage to attack.” So Gideon and his servant Purah went down and approached the outposts of the enemy camp. The Midianites, the Amalekites, and the desert tribesmen were spread out in the valley like a swarm of locusts. They had as many camels as there were grains of sand on the seashore.
