The basis of Jewish law and tradition ("halakha") is the Torah (... known as the Pentateuch or the Five Books of Moses). According to rabbinic tradition there are 613 commandments in the Torah. Some of these laws are directed only to men or to women, some only to the ancient priestly groups, the Kohanim and Leviyim (members of the tribe of Levi), some only to farmers within the land of Israel. Many laws were only applicable when the Temple in Jerusalem existed, and fewer than 300 of these commandments are still applicable today.
