The Forgotten Books of Eden, by Rutherford H. Platt, Jr., , at sacred-texts.com
Enoch instructs his sons wherefore they may not touch beef because of what comes from it.
WHOEVER defiles the soul of beasts, defiles his own soul.
2 For man brings clean animals to make sacrifice for sin, that he may have cure of his soul.
3 And if they bring for sacrifice clean animals, and birds, man has cure, he cures his soul.
4 All is given you for food, bind it by the four feet, that is to make good the cure, he cures his soul.
5 But whoever kills beast without wounds, kills his own soul and defiles his own flesh.
6 And he who does any beast any injury whatsoever, in secret, it is evil practice, and he defiles his own soul.
