Enoch - From the days of the slaughter and destruction and death ⌈of the giants⌉, from the souls of whose flesh the spirits, having gone forth, shall destroy without incurring judgement--thus shall they destroy until the day of the consummation, the great ⌈judgement⌉ in which the age shall be consummated, over the Watchers and the godless, yea, shall be wholly consummated."

Notes

The book of Enoch is not part of the canonical scriptures (The Bible) we know today and we don't know how accurate it is.

Some belive while Enoch is not inspired by God that it still serves as a historical book on the time before the flood. It's also quoted in the New Testament in Jude 1:14-15.

Because of this I wanted to include this book for historical reasons.

I would recommend reading the Bible first and foremost as it should be your foundation. Then if you are intrested you can take a look at the book of Enoch.
