1 Samuel 26:14-16

14David called to the army and to Abner son of Ner, “Won’t you answer, Abner?” Abner replied, “Who are you, that you have called to the king?”

15David said to Abner, “Aren’t you a man? After all, who is like you in Israel? Why then haven’t you protected your lord the king? One of the soldiers came to kill your lord the king.

16This failure on your part isn’t good! As surely as the Lord lives, you people who have not protected your lord, the Lord’s chosen one, are as good as dead! Now look where the king’s spear and the jug of water that was by his head are!”
