2 Samuel 1:13-16

13David said to the young man who told this to him, “Where are you from?” He replied, “I am an Amalekite, the son of a resident foreigner.”

14David replied to him, “How is it that you were not afraid to reach out your hand to destroy the Lord’s anointed?”

15Then David called one of the soldiers and said, “Come here and strike him down!” So he struck him down, and he died.

16David said to him, “Your blood be on your own head! Your own mouth has testified against you, saying ‘I have put the Lord’s anointed to death.’”
