1 Samuel 17:48-50

Modern English Version

⁴⁸ When the Philistine arose and came near to meet David, David hurried and ran toward the battle line to meet the Philistine. ⁴⁹ David put his hand in his bag and took from there a stone. And he slung it and struck the Philistine in his forehead. Therefore the stone sunk into his forehead and he fell upon his face to the ground.

⁵⁰ So David prevailed over the Philistine with a sling and with a stone. And he struck down the Philistine and slew him, but there was no sword in the hand of David.
