2 Enoch is a Jewish text preserved solely in the Slavonic language. The central theme of the text is the celestial ascent of the seventh antediluvian patriarch Enoch through the heavens, his luminous metamorphosis near the Throne of Glory, and his initiation into the heavenly mysteries. The book, which combines the features of an apocalypse and a testament, can be divided into three parts. The first part (chapters 1–38) describes Enoch’s heavenly journey that culminates in his encounter with the Deity revealing to the seer the secrets of creation. After the encounter Enoch returns to earth to instruct his children in the celestial knowledge received from God and the angels. The second part (chapters 39–67) begins with Enoch’s testamentary admonitions to his sons during his short visit to earth and ends with the second ascension of the patriarch. The third part of the book (chapters 68–73) describes the priestly functions of Enoch’s family and the miraculous birth of Melchisedek, and ends with the Flood.
