Webster(i)
49 And David put his hand in his bag, and took thence a stone, and hurled it with his sling, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
50 So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David.
51 Therefore David ran and stood upon the Philistine, and took his sword, and drew it out of its sheath, and slew him, and cut off his head with it. And when the Philistines saw their champion was dead, they fled.
