Judaism is the original of the three Abrahamic faiths (along with Christianity and Islam). Jews trace their history back to Abraham and believe there is only one God with whom they have a unique covenant. Their central religious document is the Torah (first five books of the Bible). There are multiple branches of Judaism including Orthodox, Reformed, Ashkenazi, Oriental, and Sefardii, as well as those who identify themselves as Jewish without necessarily believing in or observing Jewish law.
