Judges 7:10-12

If you are afraid to attack, go down to the camp with your servant Purah and listen to what they are saying. Afterward, you will be encouraged to attack the camp.” So he and Purah his servant went down to the outposts of the camp. The Midianites, the Amalekites and all the other eastern peoples had settled in the valley, thick as locusts. Their camels could no more be counted than the sand on the seashore.
