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 86 — The Fall of the Angels and the Demoralization of Mankind.
And again I saw with mine eyes as I slept, and I saw the heaven above, and behold a star fell from heaven, and it arose and ate and pastured amongst those oxen.
And after that I saw the large and the black oxen, and behold they all changed their stalls and pastures and their cattle, and began to live with each other.
And again I saw in the vision, and looked towards the heaven, and behold I saw many stars descend and cast themselves down from heaven to that first star, and they became bulls amongst those cattle and pastured with them [amongst them].
And I looked at them and saw, and behold they all let out their privy members, like horses, and began to cover the cows of the oxen, and they all became pregnant and bare elephants, camels and asses.
And all the oxen feared them and were affrighted at them, and began to bite with their teeth and to devour, and to gore with their horns.
And they began moreover to devour those oxen; and behold all the children of the earth began to tremble and quake before them and to flee from them.
