The Book of Enoch ( Chapter 1)

Notes
(1) THE BLESSING OF ENOCH (page 11)
This section is Enoch's introduction to the book. At 1.2, he explains how the angels (Watchers) showed him a vision of the future. At 1.5, the Watchers are mentioned; here Enoch means the run-away rebel Watchers who came to live in his area (this is described in section 3).
In the bible (Gen. 6.4), the descendants of the Watchers are described as giants or Nephilim, they may have been bigger than the local people, Enoch describes them as giants, 7.2, Andrew Collins' investigations suggest that a race of unusually large people did once exist. (See his book From the Ashes of Angels)
The main theme is that of destruction; God is going to clear away the sinners, so that good people can have peace. This is the Flood of Noah which was still some way off when Enoch wrote the book, although there are details of a ‘second end’ later in the book (see the 10 weeks).
