Judges 7:9-11

9And it came to pass in that night, that Jehovah said to him, Arise, go down to the camp; for I have given it into thy hand.

10And if thou fear to go down, go thou with Phurah thy servant down to the camp;

11and thou shalt hear what they say; and afterwards shall thy hand be strengthened, and thou shalt go down unto the camp. And he went down with Phurah his servant to the outside of the armed men that were in the camp.
