Book of Henok |Enoch is regarded as canonical by the Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church, but not by any other Christian groups.
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. For this and other reasons, the traditional Ethiopian belief is that the original language of the work was Ge’ez, whereas non-Ethiopian scholars tend to assert that it was first written in either Aramaic or Hebrew; Ephraim Isaac suggests that the Book of Enoch, like the Book of Daniel, was composed partially in Aramaic and partially in Hebrew. No Hebrew version is known to have survived. It is asserted in the book itself that its author was Enoch, before the Biblical Flood.
