The Book of the Cave of Treasures 25

1And Methuselah and Noah remained alone on the mountain, for all the children of Seth had gone down from the skirts of the mountain of Paradise to the plain where the children of Cain lived. And men, the children of Seth, had intercourse with the daughters of Cain, who conceived of them, and brought forth men, giants and the sons of giants, who were like unto towers. Now because of this certain ancient writers have fallen into error, and have written, “ The angels came down from heaven, and had intercourse with men, and by them these famous giants have been produced.” But this is not true, for those who have written in this manner did not understand [the facts]. Behold, O my brother readers, and know ye that it is not in the nature of beings of the spirit to beget, neither is it in the nature of the devils —who are unclean beings, and workers of wickedness, and lovers of adultery—to_ beget, because there are neither males nor females among them. And since the time when the angels fell, not another angel has been added to their number. And if the devils were able to have intercourse with women they would not leave unravished a single virgin in all the race of the children of men.
