Bodily desecration is disturbing—but why?

1. You reminded me of the story of David and the foreskins...

22 Then Saul ordered his attendants: “Speak to David privately and say, ‘Look, the king likes you, and his attendants all love you; now become his son-in-law.’”

23 They repeated these words to David. But David said, “Do you think it is a small matter to become the king’s son-in-law? I’m only a poor man and little known.”

24 When Saul’s servants told him what David had said, 25 Saul replied, “Say to David, ‘The king wants no other price for the bride than a hundred Philistine foreskins, to take revenge on his enemies.’” Saul’s plan was to have David fall by the hands of the Philistines.

26 When the attendants told David these things, he was pleased to become the king’s son-in-law. So before the allotted time elapsed, 27 David took his men with him and went out and killed two hundred Philistines and brought back their foreskins. They counted out the full number to the king so that David might become the king’s son-in-law. Then Saul gave him his daughter Michal in marriage.
