Judges 7:9 (KJV)

And the Lord said unto Gideon, By the three hundred men that lapped will I save you, and deliver the Midianites into thine hand: and let all the other people go every man unto his place.

So the people took victuals in their hand, and their trumpets: and he sent all the rest of Israel every man unto his tent, and retained those three hundred men: and the host of Midian was beneath him in the valley.

And it came to pass the same night, that the Lord said unto him, Arise, get thee down unto the host; for I have delivered it into thine hand.

But if thou fear to go down, go thou with Phurah thy servant down to the host:

And thou shalt hear what they say; and afterward shall thine hands be strengthened to go down unto the host. Then went he down with Phurah his servant unto the outside of the armed men that were in the host.
