1 Samuel 18:22-30

22Then Saul commanded his servants, “Speak to David secretly, saying, ‘Listen, the king delights in you, and all his servants love you; now then, become the king’s son-in-law.’ ”

23So Saul’s servants spoke these words to David. But David said, “Is it a trivial thing in your sight to become a king’s son-in-law, seeing that I am a poor man and insignificant?”

24The servants of Saul told him what David said.

25Then Saul said, “This is what you shall say to David: ‘The king wants no dowry except a hundred foreskins of the Philistines, to take vengeance on the king’s enemies.’ ” Now Saul’s intention was to cause David’s death at the hand of the Philistines.

26When his servants told David these words, it pleased him to become the king’s son-in-law. Before the time [for the marriage] arrived,

27David arose and went, he and his men, and killed two hundred Philistine men, and David brought their foreskins [as proof of death] and presented every one of them to the king, so that he might become the king’s son-in-law. So Saul gave him Michal, his [younger] daughter, as a wife.

28When Saul saw and knew that the Lord was with David, and that Michal, his daughter, loved him,

29Saul was even more afraid of David; and Saul became David’s constant enemy.

30Then the Philistine commanders (princes) came out to battle, and it happened as often as they did, that David acted more wisely and had more success than all Saul’s servants. So his name was highly esteemed.
