1 Samuel 26:14-16

14And David shouted to the troops and to Abner son of Ner, “Will you not answer me, Abner?”

“Who are you who calls to the king?” Abner replied.

15So 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? 16This 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?”
