I Samuel 18:18-23

So David said to Saul, “Who am I, and what is my life or my father’s family in Israel, that I should be son-in-law to the king?” But it happened at the time when Merab, Saul’s daughter, should have been given to David, that she was given to Adriel the Meholathite as a wife. Now Michal, Saul’s daughter, loved David. And they told Saul, and the thing pleased him. So Saul said, “I will give her to him, that she may be a snare to him, and that the hand of the Philistines may be against him.” Therefore Saul said to David a second time, “You shall be my son-in-law today.” And Saul commanded his servants, “Communicate with David secretly, and say, ‘Look, the king has delight in you, and all his servants love you. Now therefore, become the king’s son-in-law.’ ” So Saul’s servants spoke those words in the hearing of David. And David said, “Does it seem to you a light thing to be a king’s son-in-law, seeing I am a poor and lightly esteemed man?”
