The Story of David and the Giant /p3
And David ran toward the Philistine, as if to fight him with his shepherd's staff. But when he was just near enough for a good aim, he took out his sling, and hurled a stone aimed at the giant's forehead. David's aim was good; the stone struck the Philistine in his forehead. It stunned him, and he fell to the ground.
While the two armies stood wondering, and scarcely knowing what had caused the giant to fall so suddenly, David ran forward, drew out the giant's own sword, and cut off his head. Then the Philistines knew that their great warrior in whom they trusted was dead. They turned to flee to their own land; and the Israelites followed after them, and killed them by the hundred and the thousand, even to the gates of their own city of Gath.
So in that day David won a great victory and stood before all the land as the one who had saved his people from their enemies.
