2 Samuel 1:14-16

14David asked him, “Why weren’t you afraid to lift your hand to destroy the LORD ’s anointed?” 15Then David called one of his men and said, “Go, strike him down!” So he struck him down, and he died.

16For David had said to him, “Your blood be on your own head. Your own mouth testified against you when you said, ‘I killed the LORD ’s anointed.’ ”
