12 And they mourned, and wept, and fasted until even, for Saul, and for Jonathan his son, and for the people of the LORD, and for the house of Israel; because they were fallen by the sword.

13 And David said to the young man that told him, From where are you? And he answered, I am the son of a stranger, an Amalekite.

14 And David said to him, How were you not afraid to stretch forth your hand to destroy the LORD's anointed?
