45 Then David said to the Philistine, Thou comest to me with a sword and with a spear and with a shield, but I come to thee in the name of the Lord of the hosts, the God of the armies of Israel, whom thou hast dishonoured.
46 This day the Lord will deliver thee into my hand, and I will smite thee and take thy head from thee, and I will give the carcasses of the host of the Philistines this day unto the fowls of the heaven 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 congregation shall know that the Lord does not save 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 hastened and ran to do battle against the Philistine.
49 And David put his hand in his bag and took a stone from there and slang it and smote the Philistine in his forehead, that the stone remained sunk into his forehead, and he fell upon his face to the earth.
50 So David overcame the Philistine with a sling and with a stone and smote 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 with it. And when the Philistines saw their giant was dead, they fled.
