What I found the most fascinating about the book of Enoch were its references to the "Anointed One" or Messiah. That is pretty remarkable considering it is not even a cannonized text.
23 So all the days of Enoch were three hundred and sixty-five years.
24 Enoch walked with God; and he was not, for God took him.
Genesis 5
That's all we know except from the book of Jude and the book of Enoch oh and Hebrews.
I guess there is some debate on where God took him? Heaven? Also Elijah was taken away.
