1 Samuel 17:45-51

YLT(i) 45 And David saith unto the Philistine, `Thou art coming unto me with sword, and with spear, and with buckler, and I am coming unto thee in the name of Jehovah of Hosts, God of the ranks of Israel, which thou hast reproached. 46 This day doth Jehovah shut thee up into my hand—and I have smitten thee, and turned aside thy head from off thee, and given the carcase of the camp of the Philistines this day to the fowl of the heavens, and to the beast of the earth, and all the earth do know that God is for Israel. 47 and all this assembly do know that not by sword and by spear doth Jehovah save, that the battle is Jehovah's, and He hath given you into our hand.'
48 And it hath come to pass, that the Philistine hath risen, and goeth, and draweth near to meet David, and David hasteth and runneth to the rank to meet the Philistine, 49 and David putteth forth his hand unto the vessel, and taketh thence a stone, and slingeth, and smiteth the Philistine on his forehead, and the stone sinketh into his forehead, and he falleth on his face to the earth. 50 And David is stronger than the Philistine with a sling and with a stone, and smiteth the Philistine, and putteth him to death, and there is no sword in the hand of David, 51 and David runneth and standeth over the Philistine, and taketh his sword, and draweth it out of its sheath, and putteth him to death, and cutteth off with it his head; and the Philistines see that their hero is dead, and flee.
