How is it possible that, after 210 years of enslavement in an alien environment, the Jews left Egypt as Reuben, Simeon, and Levi, and not as "Rameses" or "Potiphar"? The secret lies in the way they first entered Egypt: "These are the names of the Children of Israel who came to Egypt... Reuben, Simeon, Levi, etc...."1
When Jews enter Egypt, a land whose way of life and general outlook is the very opposite of their own, the first vital step is to ensure that the children do not forget who they are and who their parents were. They must always know and ever remember that they are the Children of Israel, Jewish children, descendants of Abraham, Isaac and Jacob, of Sarah, Rebecca, Rachel and Leah.2 They must cling to their Jewish names with pride; their daily conduct must immediately identify them as Jewish children, as a Reuben, a Simeon, a Levi, and a Judah.
Such pride can only be instilled by a deep-rooted Jewish education, which imbues children with the strength of character to remain a separate, unique, distinct people, despite the severest hardships of the Egyptian exile. Such education builds an inner strength and provides the assurance that we will leave Egypt with all our children intact, with our sons and daughters proud, intense, and wholesome Jews.
Eternal Torah proclaims an ever-relevant message for all ages and for all lands — a message of particular pertinence and importance in our day and in this land: The survival of the Jewish people, the unity of the Jewish home, and the guarantee that our children will remain proud and aware Jews, is completely dependent upon a thorough, Torah-true education without compromise and without dilution.3

What was the Secret of us not basically assimmulating in Egypt? The Answer is HSHM had Joseph get rescued by his uncles people, who were Ironically half Egyptian from Hagar,. Since they were and are, our brothers from Abraham. The Ishmaelites, supposedly sold him to Egypt, and thus, helped us when there was the Great Famine (As Joseph interrupt and Jacob and his brothers were able to reunite. after his jealous brothers who were also born from some midwives, as well is Leah, But as many know, Joseph and Benjamin were the only babies (tribes) from Rachel, whom Jacob loved and worked for Laban 7yrs. for Rachel's hand. To then to his dismay married Leah, but G-d had his plans; Laban tricked Jacob and he Labored another 7 yrs. Only for 2 sons, (BTW why is Dinah not mentioned after the supposed rape, yes the Prince & the males in the village were circumcised, and were willing to live by our customs, that is a question I would like to ask.) Just like Yael is never mentioned after the Tent spike and as Heroic Female that killed Sisrah, Captain of the Guard
