1 Samuel 18:18-23

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

19When it was time to give Saul’s daughter Merab to David, she was given to Adriel the Meholathite as a wife.

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

21“I’ll give her to him,” Saul thought. “She’ll be a trap for him, and the hand of the Philistines will be against him.” So Saul said to David a second time, “You can now be my son-in-law.”

22Saul then ordered his servants, “Speak to David in private and tell him, ‘Look, the king is pleased with you, and all his servants love you. Therefore, you should become the king’s son-in-law.’”

23Saul’s servants reported these words directly to David, but he replied, “Is it trivial in your sight to become the king’s son-in-law? I am a poor commoner.”
