1 Samuel 17:48

⁴⁶this day. And the Lord shall deliver thee this day into my hand; and I will slay thee, and take away thy head from off thee, and will give thy limbs and the limbs of the army of the Philistines this day to the birds of the sky, and to the wild beasts of the earth; and all the earth shall know that there is a God in Israel.

⁴⁷And all this assembly shall know that the Lord delivers not by sword or spear, for the battle is the Lord’s, and the Lord will deliver you into our hands.

— 1 Samuel 17:48 —

⁴⁹And David stretched out his hand to his scrip, and took thence a stone, and slang it, and smote the Philistine on his forehead, and the stone penetrated through the helmet into his forehead, and he fell upon his face to the ground.
