1 Samuel 17:48-50

Darby Translation

⁴⁸ And it came to pass, when the Philistine arose, and came and advanced to meet David, that David hasted, and ran towards the ranks to meet the Philistine.

⁴⁹ And David put his hand into the bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, and the stone sank into his forehead; and he fell on his face to the earth.

⁵⁰ So David overcame the Philistine with a sling and a stone, and smote the Philistine and killed him; and there was no sword in the hand of David.
