Bible: 1 Sam. 18:21-27
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 2 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 3 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 4 to become the king’s son-in-law. Now the specified time had not yet expired 5 18:27 when David, along with his men, went out 6 and struck down two hundred Philistine men. David brought their foreskins and presented all of them to the king so he could become the king’s son-in-law. Saul then gave him his daughter Michal in marriage.
