The Erev Rav are a Mixed Multitude of Non-Jews who have accompanied Jews wherever they have gone ever since the Exodus. 6000 of them were responsible for the sin of the Golden Calf. They absorb the Mamzerim and Asuphim and Shtukim (Badukim) and Netinim as well as many Gerim and Meshukhararim. They should not call themselves Jews.
