Then David sent messengers to Saul’s son Ish-Bosheth, saying, “Give me my wife Michal. She was promised to me, and I killed a hundred Philistines to get her.”
So he and his men went out and killed two hundred Philistines. David brought all their foreskins to Saul so he could be the king’s son-in-law. Then Saul gave him his daughter Michal for his wife.
