1 Samuel 17:41-51

Goliath walked out toward David with his shield bearer ahead of him, sneering in contempt at this ruddy-faced boy. “Am I a dog,” he roared at David, “that you come at me with a stick?” And he cursed David by the names of his gods. “Come over here, and I’ll give your flesh to the birds and wild animals!” Goliath yelled. David replied to the Philistine, “You come to me with sword, spear, and javelin, but I come to you in the name of the LORD of Heaven’s Armies—the God of the armies of Israel, whom you have defied. Today the LORD will conquer you, and I will kill you and cut off your head. And then I will give the dead bodies of your men to the birds and wild animals, and the whole world will know that there is a God in Israel! And everyone assembled here will know that the LORD rescues his people, but not with sword and spear. This is the LORD’s battle, and he will give you to us!” As Goliath moved closer to attack, David quickly ran out to meet him. Reaching into his shepherd’s bag and taking out a stone, he hurled it with his sling and hit the Philistine in the forehead. The stone sank in, and Goliath stumbled and fell face down on the ground. So David triumphed over the Philistine with only a sling and a stone, for he had no sword. Then David ran over and pulled Goliath’s sword from its sheath. David used it to kill him and cut off his head.
