Understanding the exodus and other mysteries of Jewish history

[This book] "explains how the fundamental concepts of the Jewish religion originated and how they evolved and changed over time. The Law of Moses is the core of the Jewish religion and understanding its origin is necessary to put further historical developments into perspective. The influence of other cultures on Judaism and the influence of Judaism on other religions, particulary Christianity, are described. The book also explains how Judaism spread from the Middle East into Eastern Europe."--P. [4] of cover.
