David said, Yahweh who delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. Saul said to David, Go, and Yahweh shall be with you.
This fellow is defying the armies of the living God, and if none of you fellows want to go out and fight him, I'll go out and fight him.

They brought David in unto Saul and Saul said, "Oh, you can't fight him son. That man is a man of war."
