Who was the Erev Rav? According to the Ohr HaChaim, they were spies sent along by Paroah to sow seeds of dissension among the ranks of Jews. They were the rabble-rousers, and, though, they may not have been successful at making the Jewish people return to Egypt (which, they came close to doing), they were the cause of Moshe's failure to enter Eretz Yisroel, and the delaying of the Final Redemption. To make a long, painful story short, they represent one of the biggest stumbling blocks in the path of the Jewish nation.
