1 Samuel 18:27

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.
