1 Samuel 18:23-25

23When Saul’s officers made it a point to say this, David asked, “Do you think it’s easy to become the king’s son-in-law? I am a poor and unimportant person.”

24When the officers told Saul what David had said,

25Saul replied, “Tell David, ‘The king doesn’t want any payment for the bride except 100 Philistine foreskins so that he can get revenge on his enemies.’ ” In this way Saul planned to have David fall into the hands of the Philistines.
