1 Samuel 18:17-19

Amplified Bible

¹⁷ Then Saul said to David, “Behold I will give you my older daughter Merab as a wife; only be brave for me and fight the Lord’s battles.” For Saul thought, “My hand shall not be against him, but let the hand of the Philistines be against him.” ¹⁸ David said to Saul, “Who am I, and what is my life or my father’s family in Israel, that I should be the king’s son-in-law?” ¹⁹ But at the time when Merab, Saul’s daughter, should have been given to David, she was [instead] given to Adriel the Meholathite as a wife.
