Second Book of Enoch (2 Enoch, Secrets of Enoch, Slavonic Enoch)
The Second Book of Enoch is dated prior to the destruction of the Temple in 70 CE. Two angels take Enoch into 6 heavens. Enoch is then taken by Gabriel into the 7th heaven and then by Michael into the Lord's presence. This book contains the extended version of 2 Enoch, and is an easy to read translation, with notes and cross references to both scripture and contemporary writings.
