2 Samuel 1:13-16

13David inquired of the young man who had brought him the report, “Where are you from?” “I’m the son of a resident alien,” he said. “I’m an Amalekite.”

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

15Then David summoned one of his servants and said, “Come here and kill him!” The servant struck him, and he died.

16For David had said to the Amalekite, “Your blood is on your own head because your own mouth testified against you by saying, ‘I killed the Lord’s anointed.’”
