Judges 7:10-12

But if you are afraid to go down, go down to the camp with Purah your servant, and you shall hear what they say; and afterward your hands shall be strengthened to go down against the camp.” Then he went down with Purah his servant to the outpost of the armed men who were in the camp. Now the Midianites and Amalekites, all the people of the East, were lying in the valley as numerous as locusts; and their camels were without number, as the sand by the seashore in multitude.
