1 Samuel 18:27-29

New International Version - UK

²⁷ David took his men with him and went out and killed two hundred Philistines and brought back their foreskins. They counted out the full number to the king so that David might become the king’s son-in-law. Then Saul gave him his daughter Michal in marriage.

²⁸ When Saul realised that the Lord was with David and that his daughter Michal loved David, ²⁹ Saul became still more afraid of him, and he remained his enemy for the rest of his days.
