Also the Hyksos were related to the Biblical Hebrews if my memory is correct.

The Hyksos were basically a Semitic people who were able to wrestle control of Egypt from the early Second Intermediate rulers of the 13th Dynasty, inaugurating the 15th Dynasty. Their names mostly come from the West Semitic languages, and earlier suggestions that some of these people were Hurrian or even Hittite have not been confirmed. However, it is not easy to determine their origins within that Asiatic region, and at Tell el-Dab’a, the culture of the people was not static, but rapidly developed new traits and discarded old ones. Yet the reason for, and method of the cultural mixing and rapid development of Asiatics at Tell el-Dab’a remains unclear.
