Judges 7:9-11

And it came to pass the same night, that Jehovah said unto him, Arise, get thee down into the camp; for I have delivered it into thy hand. But if thou fear to go down, go thou with Purah thy servant down to the camp: and thou shalt hear what they say; and afterward shall thy hands be strengthened to go down into the camp. Then went he down with Purah his servant unto the outermost part of the armed men that were in the camp.
