1 Samuel 18:21-26

18:21 Saul said, “I will give her to him so that she may become a snare to him and the hand of the Philistines may be against him.” So Saul said to David, “Today is the second time for you to become my son-in-law.”

18:22 Then Saul instructed his servants, “Tell David secretly, ‘The king is pleased with you, and all his servants like you. So now become the king’s son-in-law.” 18:23 So Saul’s servants spoke these words privately to David. David replied, “Is becoming the king’s son-in-law something insignificant to you? I’m just a poor and lightly-esteemed man!”

18:24 When Saul’s servants reported what David had said, 18:25 Saul replied, “Here is what you should say to David: ‘There is nothing that the king wants as a price for the bride except a hundred Philistine foreskins, so that he can be avenged of his enemies.’” (Now Saul was thinking that he could kill David by the hand of the Philistines.)

18:26 So his servants told David these things and David agreed to become the king’s son-in-law. Now the specified time had not yet expired
