Deceiver \De*ceiv"er\, n.
   One who deceives; one who leads into error; a cheat; an
   impostor.
   [1913 Webster]

         The deceived and the deceiver are his.   --Job xii. 16.

   Syn: {Deceiver}, {Impostor}.

   Usage: A deceiver operates by stealth and in private upon
          individuals; an impostor practices his arts on the
          community at large. The one succeeds by artful
          falsehoods, the other by bold assumption. The
          faithless friend and the fickle lover are deceivers;
          the false prophet and the pretended prince are
          impostors.
          [1913 Webster]
