1 Samuel 18:23-30

23 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?"
24 And the servants of Saul told him, saying, "In this manner David spoke."
25 Then Saul said, "Thus you shall say to David: 'The king does not desire any dowry but one hundred foreskins of the Philistines, to take vengeance on the king's enemies.' " But Saul thought to make David fall by the hand of the Philistines.
26 So when his servants told David these words, it pleased David well to become the king's son-in-law. Now the days had not expired;
27 therefore David arose and went, he and his men, and killed two hundred men of the Philistines. And David brought their foreskins, and they gave them in full count to the king, that he might become the king's son-in-law. Then Saul gave him Michal his daughter as a wife.
28 Thus Saul saw and knew that the Lord was with David, and that Michal, Saul's daughter, loved him;
29 and Saul was still more afraid of David. So Saul became David's enemy continually.
30 Then the princes of the Philistines went out to war. And so it was, whenever they went out, that David behaved more wisely than all the servants of Saul, so that his name became highly esteemed.
