Judges 7:8-11

So Gideon sent all the Israelites home except the three hundred, who kept the supplies and shofars of those who had left. Now the Midianites were camped down below in the valley. That night YAHWEH commanded Gideon, “Get up and attack the camp; I am giving you victory over the Midianites! 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.
