45 Then said David to the Philistine, You come to me with a sword, and with a spear, and with a shield: but I come to you in the name of the LORD of hosts, the God of the armies of Israel, whom you have defied.
46 This day will the LORD deliver you into my hand; and I will strike you, and take your head from you; and I will give the carcasses of the host of the Philistines this day unto the fowls of the air, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel.
47 And all this assembly shall know that the LORD saves not with sword and spear: for the battle is the LORD'S, and he will give you into our hands.
48 And it came to pass, when the Philistine arose, and came and drew near to meet David, that David hurried, and ran toward the army to meet the Philistine.
49 And David put his hand in his bag, and took there a stone, and slung it, and struck the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
50 So David prevailed over the Philistine with a sling and with a stone, and struck the Philistine, and slew him; but there was no sword in the hand of David.
51 Therefore David ran, and stood upon the Philistine, and took his sword, and drew it out of its sheath, and slew him, and cut off his head there. And when the Philistines saw their champion was dead, they fled.
