As described in Wikipedia, Judaism is the religion, philosophy, and way of life of the Jewish people. A monotheistic religion originating in the Hebrew Bible, Judaism is considered by religious Jews to be the expression of the covenantal relationship God developed with the Children of Israel. Rabbinic Judaism holds that God revealed his laws and commandments to Moses on Mount Sinai in the form of both the Written and Oral Torah. Judaism claims a historical continuity spanning more than 3,000 years. It is one of the oldest monotheistic religions, and the oldest to survive into the present day. The Hebrews / Israelites were already referred to as "Jews" in later books of the Tanakh such as the Book of Esther, with the term Jews replacing the title "Children of Israel". Jews are an ethnoreligious group and include those born Jewish and converts to Judaism.
