The Book of Enoch is an ancient Jewish apocalyptic work traditionally attributed to Enoch, the great-grandfather of Noah. It is canonical only in the Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church. The original language was either Hebrew or Aramaic, and the only complete extant version is in Ge'ez. This translation by R.H. Charles (1917) remains the standard scholarly English translation. The book is pseudepigraphal and was highly influential on early Christian and Jewish mystical thought. It is not included in the Protestant, Catholic, or most Orthodox canons.
Enoch
Chapter 26 — Jerusalem and the Mountains, Ravines, and Streams.
And I went from thence to the middle of the earth, and I saw a blessed place "in which there were trees" with branches abiding and blooming [of a dismembered tree].
And there I saw a holy mountain, "and" underneath the mountain to the east there was a stream and it flowed towards the south.
And I saw towards the east another mountain higher than this, and between them a deep and narrow ravine: in it also ran a stream "underneath" the mountain.
And to the west thereof there was another mountain, lower than the former and of small elevation, and a ravine "deep and dry" between them : and another deep and dry ravine was at the extremities of the three mountains.
And all the ravines were deep and narrow, (being formed) of hard rock, and trees were not planted upon them.
And I marvelled at the rocks, and I marvelled at the ravine, yea, I marvelled very much.
