They were never slaves in Egypt. They were Caanite slaves that revolted and killed the upper class. This was put forth in the 70s based on archaeological data. The five of the books in Egypt, which includes Exodus, were written by the P, J, E, and D authors. Look up the social revolution theory.
>The social revolution theory--- The Israel was a group of peasant who were oppressed by the elite in Canaan. They rebelled and called“Israel”.

The theory is support by the material culture that indicate continuity with Late Bronze Age Canaanite culture and clearly point to the Canaanite roots of these hill country villagers. But it is built on a modern sociological approach to late Bronze Age society
It looks like the Jews were fooling us once again
