David Kills Goliath: The Battle Is Yahweh's
David does not answer Goliath's taunt with a better weapon but with a name. The contest at the valley is between the living God of Israel and a power that has defied him, and the outcome is announced before a stone is thrown.
1 Samuel 17:45–47: The Battle Is Yahweh's
David faces Goliath with a sling and a claim: the fight is not finally about weapons but about who is God. He comes in Yahweh's name and says plainly that the battle belongs to Yahweh.
