1 Samuel 18:20-25

20Now Saul’s daughter Michal loved David, and when this was reported to Saul, it pleased him. 21“I will give her to David,” Saul thought, “so that she may be a snare to him, and the hand of the Philistines may be against him.” So Saul said to David, “For a second time now you can be my son-in-law.”

22Then Saul ordered his servants, “Speak to David privately and tell him, ‘Behold, the king is pleased with you, and all his servants love you. Now therefore, become his son-in-law.’”

23But when Saul’s servants relayed these words to David, he replied, “Does it seem trivial in your sight to be the son-in-law of the king? I am a poor man and lightly esteemed.”

24And the servants told Saul what David had said.

25Saul replied, “Say to David, ‘The king desires no other dowry but a hundred Philistine foreskins as revenge on his enemies.’” But Saul intended to cause David’s death at the hands of the Philistines.
