After the Book of Genesis the much kinder Pharaoh died. In the beginning of the Book of Exodus a new king came to power in Egypt. The Pharaoh of Exodus did not know about Joseph or his good deeds. Instead he treated the Israelites that were Joesph's people like slaves. So thus the Jews were kept in slavery for many years. Because of a rumor floating around about a deliverer who would free the Jews, this pharaoh ordered all male Jewish babies be killed.
