2 Samuel 1:13-16

13David said to the young man who informed him, “Where are you from?” He answered, “I am the son of a foreigner (resident alien, sojourner), an Amalekite.”

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

15David called one of the young men and said, “Go, execute him.” So he struck the Amalekite and he died.

16David said to the [fallen] man, “Your blood is on your own head, for your own mouth has testified against you, saying, ‘I have killed the Lord’s anointed.’ ”
