II Samuel 1:14-16

So David said to him, “How was it you were not afraid to put forth your hand to destroy the LORD’s anointed?” Then David called one of the young men and said, “Go near, and execute him!” And he struck him so that he died. So David said to him, “Your blood is on your own head, for your own mouth has testified against you, saying, ‘I have killed the LORD’s anointed.’ ”
