So using ⌞only⌟ a sling and a stone, David proved to be stronger than the Philistine. David struck down and killed the Philistine, even though David didn’t have a sword in his hand.
So on the day of battle, not one sword or spear could be found among all the troops who were with Saul and Jonathan. But Saul and his son Jonathan had them.
David fastened Saul’s sword over his clothes and tried to walk, but he had never practiced doing this. “I can’t walk in these things,” David told Saul. “I’ve never had any practice doing this.” So David took all those things off.
Then David reached into his bag, took out a stone, hurled it from his sling, and struck the Philistine in the forehead. The stone sank into Goliath’s forehead, and he fell to the ground on his face.
David ran and stood over the Philistine. He took Goliath’s sword, pulled it out of its sheath, and made certain the Philistine was dead by cutting off his head. When the Philistines saw their hero had been killed, they fled.
He risked his life and killed the Philistine Goliath, and the Lord gave all Israel a great victory. When you saw it, you rejoiced. Why then should you sin by shedding David’s innocent blood for no reason?”
The chief priest answered, “The sword of Goliath the Philistine, whom you killed in the Elah Valley, is here. It is wrapped in a cloth behind the priestly ephod. If you want to take it, take it. There’s no other weapon here.” David said, “There’s none like it. Let me have the sword.”
