The priest replied, ‘The sword of Goliath the Philistine, whom you killed in the Valley of Elah, is here, wrapped in a cloth behind the ephod. If you want to take it for yourself, then take it, for there isn’t another one here.’ ‘There’s none like it! ’ David said. ‘Give it to me.’
David strapped his sword on over the military clothes and tried to walk, but he was not used to them. ‘I can’t walk in these,’ David said to Saul, ‘I’m not used to them.’ So David took them off.
So on the day of battle not a sword or spear could be found in the hand of any of the troops who were with Saul and Jonathan; only Saul and his son Jonathan had weapons.
David put his hand in the bag, took out a stone, slung it, and hit the Philistine on his forehead. The stone sank into his forehead, and he fell face down to the ground.
David ran and stood over him. He grabbed the Philistine’s sword, pulled it from its sheath, and used it to kill him. Then he cut off his head. When the Philistines saw that their hero was dead, they fled.
He took his life in his hands when he struck down the Philistine, and the Lord brought about a great victory for all Israel. You saw it and rejoiced, so why would you sin against innocent blood by killing David for no reason? ’
