1 Samuel 18:25 - Clarke's commentary and critical notes on the Bible

And Saul said, Thus shall ye say to David, The king desireth not any dowry, but an hundred foreskins of the Philistines, to be avenged of the king's enemies. But Saul thought to make David fall by the hand of the Philistines. But a hundred foreskins - That is, Thou shalt slay one hundred Philistines, and thou shalt produce their foreskins, as a proof, not only that thou hast killed one hundred men, but that these are of the uncircumcised. A custom similar to this still prevails among the Abyssinians, according to Bruce. See his Travels.
