1 Samuel 18:18-23

18And 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?” 19So when it was time1 to give Saul’s daughter Merab to David, she was given in marriage to Adriel of Meholah.

20Now 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.”

22Then 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.’”

23But 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.”
