What’s the Truth About . . . the Jews in Egypt Keeping Their Jewish Names, Language and Dress?

Misconception: The Midrash states that after centuries of servitude, G-d redeemed the Jews from Egypt in the merit of the rigorous preservation of their own names, language and mode of dress.

Fact: While these three factors certainly would have contributed to the Jews maintaining an independent identity, and some of them are mentioned in various midrashim, there is no known classical midrash that presents a list of exclusively these three points of merit.
