XVII-XXXVII. Enoch's Journeys through the Earth and Sheol.
The Book of Enoch (also 1 Enoch) is an ancient Jewish religious work, traditionally ascribed to Enoch, the great-grandfather of Noah. It is not part of the biblical canon as used by Jews, apart from Beta Israel. It is regarded as canonical by the Ethiopian Orthodox Church and Eritrean Orthodox Church, but no other Christian group.
Western scholars believe that its older sections (mainly in the Book of the Watchers) date from about 300 BC, and the latest part (Book of Parables) probably was composed at the end of the 1st century BC.
It is wholly extant only in the Ge’ez language, with Aramaic fragments from the Dead Sea Scrolls and a few Greek and Latin fragments. There is no consensus among scholars about the original language: some propose Aramaic, others Hebrew, while the probable thesis, according to E. Isaac, is that 1 Enoch, like Daniel, was composed partially in Aramaic and partially in Hebrew.:6 Ethiopian scholars generally hold that Ge’ez is the language of the original from which the Greek and Aramaic copies were made, pointing out that it is the only language in which the complete text has yet been found.
A short section of 1 Enoch (1 En 1:9) is quoted in the New Testament (Letter of Jude 1:14-15), and is there attributed to “Enoch the Seventh from Adam” (1 En 60:8). It is argued that all the writers of the New Testament were familiar with it and were influenced by it in thought and diction.
