1 Samuel 18:17 ERV

[17] One day Saul said to David, "Here is my oldest daughter, Merab. I will let you marry her. Then you will be like a son to me and you will be a real soldier. Then you will go and fight the LORD's battles." Saul was really thinking, "Now I won't have to kill David. I will let the Philistines kill him for me."
