Bible Verses About Circumcision: Sometimes performed on slain enemies

And Saul said: Speak thus to David: The king desireth not any dowry, but only a hundred foreskins of the Philistines, to be avenged of the king's enemies. Now Saul thought to deliver David into the hands of the Philistines.

And when his servants had told David the words that Saul had said, the word was pleasing in the eyes of David to be the king's son in law.

And after a few days David rose up, and went with the men that were under him, and he slew of the Philistines two hundred men, and brought their foreskins and numbered them out to the king, that he might be his son in law. Saul therefore gave him Michol, his daughter, to wife.
