1 Samuel 18:18-23

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

19When the time came for Merab, Saul’s daughter, to be given to David, she instead was given in marriage to Adriel, who was from Meholah.

20Now Michal, Saul’s daughter, loved David. When they told Saul about this, it pleased him.

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

22Then Saul instructed his servants, “Tell David secretly, ‘The king is pleased with you, and all his servants like you. So now become the king’s son-in-law.”

23So Saul’s servants spoke these words privately to David. David replied, “Is becoming the king’s son-in-law something insignificant to you? I’m just a poor and lightly-esteemed man!”
