According to the Arizal, in every generation, the souls of the Erev Rav are reincarnated in numerous individuals.[4] The Zohar, which is the foundational text for Kabbalistic thought, says the Erev Rav not only exist in every generation, but they are the cause for most of the problems affecting the Jewish people.[5] Currently, the term "Erev Rav" is used by Jews in a derogatory manner to describe someone who is perceived as a traitor.[6]
