1 Samuel 18:17

18:17 Then Saul said to David, “Here’s my oldest daughter, Merab. I want to give her to you in marriage. Only be a brave warrior for me and fight the battles of the Lord.” For Saul thought, “There’s no need for me to raise my hand against him. Let it be the hand of the Philistines!”

1 Samuel 18:21

18:21 Saul said, “I will give her to him so that she may become a snare to him and the hand of the Philistines may be against him.” So Saul said to David, “Today is the second time for you to become my son-in-law.”

1 Samuel 18:29

18:29 Saul became even more afraid of him. Saul continued to be at odds with David from then on.
