This translation contains all 3 Books of Enoch: 1) 1 Book of Enoch (Also called The Ethiopic Book of Enoch) 2) 2 Book of Enoch (Also called The Slavonic Book of Enoch, The Secrets of Enoch). Also contains the extended version of 2 The Book of Enoch, The Exaltation of Melchizedek. 3) 3 Book of Enoch (Also called The Hebrew Book of Enoch) Although this book is considered apocryphal for the Western canon, it is contained in the Ethiopic Bible. It was considered sacred by some but it was left out of the Bible and disappeared for centuries until it was rediscovered in Ethiopic. According to most scholars, part of it was written in third century BCE and part of it in the first century CE (the part related to the Son of Man). Although the oldest complete copies of 1 Enoch are K-9 or Kebran 9, dated late fourteenth early fifteenth century and Ethiopian Monastic Microfilm Library (EMML 2080) of the fifteenth or fourteenth century, fragments found in Qumramin the 1950s are more than 2000 years old. Other old important manuscripts are Abbadianus 55 (possibly fifteenth century) and British Museum Orient 485 (first half of the sixteenth century). The 2nd Book of Enoch, the Slavonic Enoch, is another apocryphal book, found complete only in Old Slavonic manuscripts, and it was once present in the Old Slavonic Bible. It's usually dated to the first century CE although Matthew Black in The Oxford Guide to People & Places of the Bible state that there is no manuscript earlier than the fourteenth century BCE. The 3rd Book of Enoch, the Hebrew Enoch, is a Rabbinic text originally written in Hebrew usually dated to the fifth century CE. Some experts believe it was written by Rabbi Ishmael (second century CE).
