1 Samuel 17:32-50

32And David said to Saul, Let no man’s heart fail because of him; thy servant will go and fight with this Philistine. 33And Saul said to David, Thou art not able to go against this Philistine to fight with him: for thou art but a youth, and he a man of war from his youth. 34And David said to Saul, Thy servant kept his father’s sheep, and there came a lion, and a bear, and took a lamb out of the flock:1 35And I went after him, and smote him, and delivered it out of his mouth: and when he arose against me, I caught him by his beard, and smote him, and slew him. 36Thy servant slew both the lion and the bear: and this uncircumcised Philistine shall be as one of them, seeing he hath defied the armies of the living God. 37David said moreover, The LORD that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said to David, Go, and the LORD be with thee. 38And Saul armed David with his armour, and he put an helmet of brass upon his head; also he armed him with a coat of mail.2 39And David girded his sword upon his armour, and he tried to go; for he had not proved it . And David said to Saul, I cannot go with these; for I have not proved them . And David put them off from him.

40And he took his staff in his hand, and chose for himself five smooth stones out of the brook, and put them in a shepherd’s bag which he had, even in a bag; and his sling was in his hand: and he drew near to the Philistine.34 41And the Philistine advanced and drew near to David; and the man that bore the shield went before him. 42And when the Philistine looked about, and saw David, he disdained him: for he was a youth, and ruddy, and of a fair countenance. 43And the Philistine said to David, Am I a dog, that thou comest to me with staffs? And the Philistine cursed David by his gods. 44And the Philistine said to David, Come to me, and I will give thy flesh to the fowls of the air, and to the beasts of the field. 45Then said David 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 hosts, the God of the armies of Israel, whom thou hast defied. 46This day will the LORD deliver thee into my hand; and I will smite thee, and take thy head from thee; and I will give the dead bodies of the host of the Philistines this day to 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.5 47And all this assembly shall know that the LORD saveth not with sword and spear: for the battle is the LORD’S, and he will give you into our hands.

48And it came to pass, when the Philistine arose, and came and drew near to meet David, that David hasted, and ran toward the army to meet the Philistine. 49And David put his hand in his bag, and took from there a stone, and slung it with his sling, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth. 50So David prevailed over 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.
