And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
Goliath stalked forward with all his brass and iron grandeur; David ran lightly toward him with one aim only, to strike true. See how swiftly the mighty fall: while the giant prepared his stroke, David's stone found the one gap in his armor, sank into his forehead, and in a twinkling brought him down, a small thing, but God's providence made it sufficient, and life went out as easily as it had come in.

Commenting on 1 Samuel 17:48-58
And David put his hand in his bag,.... The shepherd's scrip, in which he had put the five stones he took out of the brook: and took thence a stone; and put it into his sling he had in his hand: and slang it, and smote the Philistine in his forehead; it is made a difficulty of how he should smite him on his forehead...
smote the Philistine in his forehead--At the opening for the eyes--that was the only exposed part of his body.
