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 outposts of the armed men who were in the camp. And the Midianites and the Amalekites and all the people of the East lay along the valley like locusts in abundance, and their camels were without number, as the sand that is on the seashore in abundance.
