And David put his hand in his bag and took out a stone and slung it and struck the Philistine on his forehead. The stone sank into his forehead, and he fell on his face to the ground.
Here is 1. The engagement between the two champions, Sa1 17:48. To this engagement the Philistine advanced with a great deal of state and gravity; if he must encounter a pigmy, yet it shall be with the magnificence of a giant and a grandee.
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.
