15. So David said to Abner, “You are a man, aren’t you? And who in Israel is your equal? Why then did you not protect your lord the king when one of the people came to destroy him? 

16. This thing you have done is not good. As surely as the LORD lives, all of you deserve to die, since you did not protect your lord, the LORD’s anointed. Now look around. Where are the king’s spear and water jug that were by his head?”

1 Samuel 26:15-16
