1 Samuel 17:46-50 Christian Standard Bible (CSB)
46 Today, the Lord will hand you over to me. Today, I’ll strike you down, remove your head, and give the corpses[a] of the Philistine camp to the birds of the sky and the wild creatures of the earth. Then all the world will know that Israel has a God, 47 and this whole assembly will know that it is not by sword or by spear that the Lord saves, for the battle is the Lord’s. He will hand you over to us.”
48 When the Philistine started forward to attack him, David ran quickly to the battle line to meet the Philistine. 49 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 facedown to the ground. 50 David defeated the Philistine with a sling and a stone. David overpowered the Philistine and killed him without having a sword.
