1 Samuel 26:15-16

15David said, “You’re a man, aren’t you? And who is like you in Israel? Why didn’t you guard your lord the king? Someone came to destroy your lord the king.

16What you have done is not good. As surely as the LORD lives, you and your men must die, because you did not guard your master, the LORD ’s anointed. Look around you. Where are the king’s spear and water jug that were near his head?”
