jews weren't slaves in egypt. thats all biblical.
Would you care to explain more ?
"The Hebrew Bible also records that a large number of Jews took refuge in Egypt after the destruction of the Kingdom of Judah in 597 BC, and the subsequent assassination of the Jewish governor, Gedaliah. (2 Kings 25:22-24, Jeremiah 40:6-
On hearing of the appointment, the Jews that had fled to Moab, Ammon, Edom and in other countries returned to Judah. (Jeremiah 40:11-12) However, before long Gedaliah was assassinated, and the population that was left in the land and those that had returned ran away to Egypt for safety. (2 Kings 25:26, Jeremiah 43:5-7) The numbers that made their way to Egypt is subject to debate. In Egypt, they settled in Migdol, Tahpanhes, Noph, and Pathros. (Jeremiah 44:1)"
(from Wikipedia: http://en.wikipedia.org/wiki/History_of_the_Jews_in_Egypt)
From what I know (and I'm not an expert) Jews were in egipt and had high social and political position under Hyksos dynasty. That would explain why Jews had Egyptian slaves.
After Hyksos dynasty fall, Jews as theyr supporters fell in disgrace and slavery.
Egyptian had custom of destroying any records of theyr political oponents (it even had religious basis I think, they destroyed mummies, statues, everything.) so this would explain why nothing was found about jews good position under Heksosi. Ancient Egyptians also didn't write about theyr failures so for sure they wouldn't admit that Jews did manage to escape and if they had records of having Jews as slaves they would destroyd it to say: "see, we didn't lose, nothing realy happened"
My life will be empty if I wont be able to hunt Jews with my chariot...
(also forgive me my engrish)
Also building obelisks and other stuff would be nice in order to improve your renown.
