About this text
1 Enoch is a collection of five books attributed to the patriarch Enoch, the seventh from Adam. It describes the fall of the Watchers, the giants they fathered with human women, the coming judgment, Enoch's astronomical visions, and his dream of history from the Flood to the Messianic age. The Book of Jude quotes it directly (Jude 1:14–15), and echoes of Enoch's language appear throughout the New Testament — especially in its descriptions of angelic rebellion and final judgment. The text survived in complete form only in Ge'ez (classical Ethiopic), preserved by the Ethiopian Orthodox Tewahedo Church, which treats it as canonical scripture to this day. R.H. Charles translated it into English in 1917 working from the Ethiopic manuscripts.
