1 Samuel 26:14-16

14And David cried to the people, and to Abner the son of Ner, saying, Answerest thou not, Abner? Then Abner answered and said, Who art thou that criest to the king?

15And David said to Abner, Art not thou a man? and who is like to thee in Israel? and why hast thou not guarded thy lord the king? for one of the people came in to destroy the king thy lord.

16This thing is not good which thou hast done. As Jehovah liveth, ye are worthy to die, because ye have not guarded your master, Jehovah's anointed. And now see where the king's spear is, and the cruse of water that was at his head.
