1 Samuel 18:27-29

Amplified Bible

²⁷ David arose and went, he and his men, and killed two hundred Philistine men, and David brought their foreskins [as proof of death] and presented ^[a]every one of them to the king, so that he might become the king’s son-in-law. So Saul gave him Michal, his [younger] daughter, as a wife. ²⁸ When Saul saw and knew that the Lord was with David, and that Michal, his daughter, loved him, ²⁹ Saul was even more afraid of David; and Saul became David’s constant enemy.
