'Foreskins' in the Bible

Then Saul said, "This [is] what you must say to David: '{The king desires no bride price} except for a hundred foreskins of [the] Philistines, to avenge himself on the enemies of the king.'" (Now Saul had planned to allow David to fall by the hand of [the] Philistines.)

And David got up, and he and his men went and struck down two hundred men [of the] Philistines. Then David brought their foreskins, and {they presented the full number} to become the king's son-in-law. Then Saul gave him Michal his daughter as [his] wife.
