1 Samuel 18:17-30 - David Marries Saul's Daughter Michal
17 Saul said to David, "Behold, my elder daughter Merab, I will give her to you as wife. Only be valiant for me, and fight Yahweh's battles." For Saul said, "Don't let my hand be on him, but let the hand of the Philistines be on him."
18 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?" 19 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 wife.
20 Michal, Saul's daughter, loved David; and they told Saul, and the thing pleased him. 21 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, "You shall this day be my son-in-law a second time."
22 Saul commanded his servants, "Talk with David secretly, and say, 'Behold, the king has delight in you, and all his servants love you: now therefore be the king's son-in-law.'" 23 Saul's servants spoke those words in the ears of David. David said, "Does it seems to you a light thing to be the king's son-in-law, since I am a poor man, and lightly esteemed?"
24 The servants of Saul told him, saying, "David spoke like this."
25 Saul said, "You shall tell David, 'The king desires no dowry except one hundred foreskins of the Philistines, to be avenged of the king's enemies.'" Now Saul thought to make David fall by the hand of the Philistines.
26 When his servants told David these words, it pleased David well to be the king's son-in-law. The days were not expired; 27 and David arose and went, he and his men, and killed of the Philistines two hundred men; and David brought their foreskins, and they gave them in full number to the king, that he might be the king's son-in-law. Saul gave him Michal his daughter as wife. 28 Saul saw and knew that Yahweh was with David; and Michal, Saul's daughter, loved him. 29 Saul was yet the more afraid of David; and Saul was David's enemy continually.
30 Then the princes of the Philistines went forth: and it happened, as often as they went forth, that David behaved himself more wisely than all the servants of Saul; so that his name was highly esteemed.
