The Bitter Exile. How Long?

After a long and bitter exile, the unimaginable miracle occurred and the walls of Egypt collapsed before the Jews. A vast people went out to eternal freedom, on its way back to the inheritance of its forefathers.The Torah looks back and summarizes the number of years during which we left the Land of Israel and suffered in Egypt: 430.But there is a problem: it is impossible that we were in Egypt for 430 years. A simple calculation of the ages of the members of Moshe’s family, brings us to the obvious conclusion that the Jews were there at most 350?Why shorten or extend it? Eliminate it.
