The Book of Jubilees presents itself as "the history of the division of the days of the Law, of the events of the years, the year-weeks, and the jubilees of the world" and claims to be a revelation of God to Moses, given through the Angel of the Presence in addition to the written Law received by Moses on Mount Sinai; and, while the written Law was to be imparted to all, this was to be a secret tradition entrusted only to the saints of each generation, to Enoch, Methuselah, Noah, and Shem, then to Abraham, Isaac, Jacob, and Levi, and finally to the priests and scribes of the latter times.
