I saw in a response to an article on Israelnn.com the following: "the Erev Rav, that conned us with their sincerity in converting and dragged along with us @ Y'ziat Mitzraim, and we have been suffering because of them since then. Our great sages have foretold that they will be in control of the land after we regain it (1948). But just before Moshiach's arrival, they will be in total control; it's all part of the redemption process. They are called the enemy within and will be our worst enemies. Not my words, but this is from our Torah and holy sages."
I remember reading something similar to this concept before as well.
Can anybody here provide a legitimate source for this idea (if one exists) and what that source actually says?
Does the term "Erev Rav" apply to any group of trouble-makers within the Jewish people during a particular generation? (i.e. those that were involved in the Golden Calf 3500 years ago, and those that work to expel fellow Jews from their homes today, etc.)?
Either way, we are still required to love these Jews just the same as all others, so what is the point of identifying who is part of the Erev Rav and who is not? Will knowing this information somehow help us hasten the Redemption?
