And who was the "mixed crowd"?

EREV RAV Hebrew name for the magicians of Egypt that Moses took with him. And who was the "mixed crowd"? Were they Lilies, Ethiopians or Cypriots? Weren't all Egyptians and not all from Egypt? Had they been a mixture of many different nations, the plural verb 'Alu would not have been used instead of the singular Ala (Ex. XII, 38) In fact, however, the "mixed multitude" consisted entirely of a people whose members spoke one language: namely, all the magicians of Egypt and all their magicians, as it is written, "And the magicians of Egypt also did it. in the same way with your incantations" (Ex 7, 2) the language of impurity and betrayal of holiness ; because they wanted to oppose the wonderful works of the Holy One, blessed be He. When they saw the signs and wonders that Moses did in Egypt, they came to Moses to be converted. The Saint said to Moses "Do not receive them." However, Moses replied, "Sovereign of the universe, now that you have seen your power, you want to accept our faith, so that you can see your power. and they will learn that there is no Gd like you." And Moses He accepted them
