2 Samuel 1:13-15

13 David said to the young man who told him, "Where are you from?"He answered, "I am the son of a foreigner, an Amalekite."

14 David said to him, "How were you not afraid to put forth your hand to destroy the Lord's anointed?"

15 David called one of the young men, and said, "Go near, and fall on him." He struck him, so that he died.
