Yes, for instance the Rabbis today insist that the Jews were only in Egypt 200 years despite the known cronology of 1 Kings 6:1 says 400 years...
A rabbi I asked said the 400 years started with Isaac!!!
one source quoted that.240 year..discrepancy from the Hebrew encyclopedia.......
Its also in church history as to the final split between Judahism and Christianity........
