Judges 7:8-11

So the people took provisions and their trumpets in their hands. And he sent away all the rest of Israel, every man to his tent, and retained those three hundred men. Now the camp of Midian was below him in the valley. It happened on the same night that the LORD said to him, “Arise, go down against the camp, for I have delivered it into your hand. 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.
