1 Samuel 17:50-53

David defeated Goliath with a sling and a rock. He killed him without even using a sword. David ran over and pulled out Goliath's sword. Then he used it to cut off Goliath's head. When the Philistines saw what had happened to their hero, they started running away. But the soldiers of Israel and Judah let out a battle cry and went after them as far as Gath and Ekron. The bodies of the Philistines were scattered all along the road from Shaaraim to Gath and Ekron. When the Israelite army returned from chasing the Philistines, they took what they wanted from the enemy camp.
