Question
OS 285 Dear Rabbi, Hi, I am attending a community college in Daytona Beach before I go to Berkeley, and I have a couple questions concerning the angle my humanities teacher takes. He states that there was no great Exodus out of Egypt for the Jews because archaeologists could not find trash in the desert enough for the "supposed" thousands of Jews migrating out from Egypt. He also states that the Jews were not slaves in Egypt. He admits to there being a small caste of Jews that were slaves, but not on the popular belief scale. I am the only Jew in class because he asked any Hebrew to raise their hand and mine was the only one that went up, so I stand alone when I ask him and question him. If you could give me any information about this I would feel better about the subject. These are only a few of the things my teacher has said that has made me anxious and on guard. Thank you.

Question
what percentage of the jews did not follow Moses out of egypt and what happened to them? do we know who they are and are they still considered to be jewish?
