So David prevailed over the Philistine with a sling and with a stone, and struck the Philistine, and killed him; there was no sword in the hand of David.
So on the day of the battle there was neither sword nor spear found in the hand of any of the people with Saul and Jonathan; but Saul and Jonathan his son had them.
And David girded his sword over his armor, and he tried in vain to go, for he was not used to them. Then David said to Saul, “I cannot go with these; for I am not used to them.” And David put them off.
And David put his hand in his bag and took out a stone, and slung it, and struck the Philistine on his forehead; the stone sank into his forehead, and he fell on his face to the ground.
Then David ran and stood over the Philistine, and took his sword and drew it out of its sheath, and killed him, and cut off his head with it. When the Philistines saw that their champion was dead, they fled.
for he took his life in his hand and he slew the Philistine, and the Lord wrought a great victory for all Israel. You saw it, and rejoiced; why then will you sin against innocent blood by killing David without cause?”
And the priest said, “The sword of Goliath the Philistine, whom you killed 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 but that here.” And David said, “There is none like that; give it to me.”
