Then said David to the Philistine, You come to me with a sword, and with a spear, and with a javelin: but I come to you in the name of Yahweh of hosts, the God of the armies of Israel, whom you have defied.
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.
