1 Samuel 18:20

16 But all Israel and Judah loved David, because he was leading them out to battle and back.

17 Then Saul said to David, “Here is my older daughter Merab. I will give her to you in marriage. Only be valiant for me and fight the LORD’s battles.” But Saul was thinking, “I need not raise my hand against him; let the hand of the Philistines be against him.”

18 And David said to Saul, “Who am I, and what is my family or my father’s clan in Israel, that I should become the son-in-law of the king?”

19 So when it was time to give Saul’s daughter Merab to David, she was given in marriage to Adriel of Meholah.

20 Now Saul’s daughter Michal loved David, and when this was reported to Saul, it pleased him.

21 “I will give her to David,” Saul thought, “so that she may be a snare to him, and the hand of the Philistines may be against him.” So Saul said to David, “For a second time now you can be my son-in-law.”

22 Then Saul ordered his servants, “Speak to David privately and tell him, ‘Behold, the king is pleased with you, and all his servants love you. Now therefore, become his son-in-law.’”

23 But when Saul’s servants relayed these words to David, he replied, “Does it seem trivial in your sight to be the son-in-law of the king? I am a poor man and lightly esteemed.”

24 And the servants told Saul what David had said.
