So David sent messengers to Ishbosheth, Saul’s son, saying, “Give me my wife Michal, whom I betrothed to myself for a hundred foreskins of the Philistines.”
therefore David arose and went, he and his men, and killed two hundred men of the Philistines. And David brought their foreskins, and they gave them in full count to the king, that he might become the king’s son-in-law. Then Saul gave him Michal his daughter as a wife.
