Enoch - And I went beyond it and saw seven magnificent mountains all differing each from the other, and the stones (thereof) were magnificent and beautiful, magnificent as a whole, of glorious appearance and fair exterior: ⌈⌈three towards⌉⌉ the east, ⌈⌈one⌉⌉ founded on the other, and three towards the south, one upon the other, and deep rough ravines, no one of which joined with any other.

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.
