Saul said to David, You are not able to go against this Philistine to fight with him; for you are but a youth, and he a man of war from his youth.
And of course the men of Israel, when they saw this, their hearts were encouraged, and they all came out of their tents and began charging after the Philistines. And there was a great slaughter of the Philistines that day. So the Lord delivered the Philistine there in the hands of David.
