So David prevailed over the Philistine with a sling and with a stone. And he struck down the Philistine and slew him, but there was no sword in the hand of David.
So on the day of battle neither sword nor spear were found in the hand of any of the people who were with Saul and Jonathan. But they were found in the hand of Saul and Jonathan his son.
David secured his sword to his armor and tried to walk, but he was not used to it, for he had not tested them. And David said to Saul, “I cannot walk with these, for I have not tested them.” So David took them off.
David put his hand in his bag and took from there a stone. And he slung it and struck the Philistine in his forehead. Therefore the stone sunk into his forehead and he fell upon his face to the ground.
Therefore David ran and stood over the Philistine. Then he took his sword and drew it from out of its sheath, and he finished him off and he cut off his head with it. When the Philistines saw their champion was dead, they fled.
For he took his life in his hand and struck down the Philistine, and the Lord made a great salvation for all Israel. You saw it and rejoiced. Now why then would you sin against innocent blood, to kill David without cause?”
The priest said, “The sword of Goliath the Philistine, whom you struck down in the Valley of Elah, behold, it is here, wrapped in a cloth behind the ephod. If you will take that, take it, for there is none here except that one.” And David said, “There is none like it. Give it to me.”
