158 And now, the giants, who are produced from the spirits and flesh, shall be called evil spirits upon 9the earth, and on the earth shall be their dwelling. Evil spirits have proceeded from their bodies; because they are born from men and from the holy Watchers is their beginning and primal origin; 10they shall be evil spirits on earth, and evil spirits shall they be called. [As for the spirits of heaven, in heaven shall be their dwelling, but as for the spirits of the earth which were born upon the earth, on the earth shall be their dwelling.] 11And the spirits of the giants afflict, oppress, destroy, attack, do battle, and work destruction on the earth, and cause trouble: they take no food, but nevertheless 12hunger and thirst, and cause offences. And these spirits shall rise up against the children of men and against the women, because they have proceeded from them.
The Book of Enoch (also 1 Enoch; Ge’ez: mätṣḥäfä henok) is an ancient Jewish religious work, ascribed by tradition to Enoch, the great-grandfather of Noah, although modern scholars estimate the older sections (mainly in the Book of the Watchers) to date from about 300 BC, and the latest part (Book of Parables) probably to the first century BC.
