But the Book of Enoch says differently
Chapter 15
1Then addressing me, He spoke and said, Hear, neither be afraid, O righteous Enoch, you scribe of righteousness: approach hither, and hear my voice. Go, say to the Watchers of heaven, who have sent you to pray for them, You ought to pray for men, and not men for you.
2Wherefore have you forsaken the lofty and holy heaven, which endures for ever, and have lain with women; have defile yourselves with the daughters of men; have taken to yourselves wives; have acted like the sons of the earth, and have begotten an impious offspring? (23)
(23) An impious offspring. Literally, "giants" (Charles, p. 82; Knibb, p. 101).
3You being spiritual, holy, and possessing a life which is eternal, have polluted yourselves with women; have begotten in carnal blood; have lusted in the blood of men; and have done as those who are flesh and blood do.
4These however die and perish.
5Therefore have I given to them wives, that they might cohabit with them; that sons might be born of them; and that this might be transacted upon earth.
6But you from the beginning were made spiritual, possessing a life which is eternal, and not subject to death for ever.
7Therefore I made not wives for you, because, being spiritual, your dwelling is in heaven.
8Now the giants, who have been born of spirit and of flesh, shall be called upon earth evil spirits, and on earth shall be their habitation. Evil spirits shall proceed from their flesh, because they were created from above; from the holy Watchers was their beginning and primary foundation. Evil spirits shall they be upon earth, and the spirits of the wicked shall they be called. The habitation of the spirits of heaven shall be in heaven; but upon earth shall be the habitation of terrestrial spirits, who are born on earth. (24)
(24) Note the many implications of vss. 3-8 regarding the progeny of evil spirits.
9The spirits of the giants shall be like clouds, (25) which shall oppress, corrupt, fall, content, and bruise upon earth.
(25) The Greek word for "clouds" here, nephelas, may disguise a more ancient reading, Napheleim (Nephilim).
10They shall cause lamentation. No food shall they eat; and they shall be thirsty; they shall be concealed, and shall not (26) rise up against the sons of men, and against women; for they come forth during the days of slaughter and destruction.
(26) Shall not. Nearly all manuscripts contain this negative, but Charles, Knibb, and others believe the "not" should be deleted so the phrase reads "shall rise up."
