2 Samuel 3:13-14

3:13 So David said, “Good! I will make an agreement with you. I ask only one thing from you. You will not see my face unless you bring Saul’s daughter Michal when you come to visit me.”

3:14 David sent messengers to Ish-bosheth son of Saul with this demand: “Give me my wife Michal whom I acquired for a hundred Philistine foreskins.”
