1 Samuel 18:20-27

20Now Michal, Saul’s daughter, loved David; and when they told Saul, it pleased him.

21Saul said, “I will give her to him so that she may become a snare (bad influence, source of trouble) to him, and that the hand of the Philistines may be against him.” So Saul said to David for a second time, “You shall be my son-in-law today.”

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.
