Epikoros (or Apikoros or Apikores or Epicurus; Hebrew: אפיקורוס, lit. "Heretic", pl. Epicorsim ) is a Jewish term cited in the Mishnah, referring to one who does not have a share in the world to come: The Rabbinic literature uses merely the term Epikoros, without a specific reference to the Greek philosopher Epicurus, yet it is apparent that the term is derived from the Greek philosopher's name, a philosopher whose views contradicted Jewish scripture, the strictly monotheistic conception of God in Judaism and the Jewish belief in the world to come.
