David left his baggage in the hand of the keeper of the baggage, and ran to the army, and came and greeted his brothers.
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. So a fellow ran and told Saul the fact that they had a volunteer who had volunteered to go out and fight: David. And so they brought David in to fight Goliath. They brought David in unto Saul and Saul said, "Oh, you can't fight him son. That man is a man of war."
