1 Samuel 18:18-23

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

19But when it was time to give Saul’s daughter Merab to David in marriage, she was given as wife to Adriel the Meholathite instead.

20Now Saul’s daughter Michal loved David. When they told Saul, the matter pleased him.

21Saul thought, “I will give her to him, so that she may become a snare to him—and the hand of the Philistines will be against him.” So Saul said to David, “You can still become my son-in-law, even today, with the second one.”

22Then Saul commanded his courtiers, “Speak with David privately and say, ‘Behold, the king delights in you and all his courtiers love you. So now, become the king’s son-in-law!’”

23So Saul’s courtiers whispered these words in David’s ears. But David said, “Is it a light thing to you becoming the king’s son-in-law, considering that I am a poor man and of little account?”
