Free Fallen Angels, the Watchers, and the Origins of Evil by Joseph B. Lumpkin

them not have power over the sons of the righteous from now and forever.” And the Lord our God commanded the angels to bind all of them.
                And the Watchers came to Enoch, whom God had taken up into heaven, and begged him to intercede before God on their behalf.
                Then God answered and said, ”No request that the Watchers, or their children make of you shall be granted them on their behalf; for they hope to live an eternal life, and that each one of them will live five hundred years.”
                And God answered and said to Enoch, “Do not be afraid, Enoch, you righteous man and scribe of righteousness.   Approach and hear my voice. Go and say to the Watchers of heaven, for whom you have come to intercede: You should intercede for men, and not men for you. Why and for what cause have you left the high, holy, and eternal heaven, and had sex with women, and defiled yourselves with the daughters of men and taken to yourselves wives, and done like the children of earth, and begotten giants (as your) sons? Though you were holy, spiritual, living the eternal life, you have defiled yourselves with the blood of women, and have begotten children with the blood of flesh, and, as the children of men, you have lusted after flesh and blood like those who die and are killed.
                This is why I have given men wives that they might impregnate them, and have children by them, that deeds might continue on the earth. But you were formerly spiritual, living the eternal life, and immortal for all generations of the world. Therefore I have not appointed wives for you. You are spiritual beings of heaven, and in heaven was your dwelling place. Only after death will man know what you have known.
                “For the children of this world marry, and are given in marriage: But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage, neither can they die any more.   For they are equal unto the angels, and are the children of God, being the children of the resurrection.”
                And now, the giants, who are produced from the spirits and flesh, shall be called evil spirits on the earth, and shall live on the earth. Evil spirits have come out from their bodies because they are born from men and from the holy Watchers, their beginning is of primal origin, and they shall be called spirits of the evil ones.   As for the spirits of heaven, in heaven shall be their dwelling, but as for the spirits of the earth which were born on the earth, on the earth shall be their dwelling.
    And the spirits of the giants afflict, oppress, destroy, attack, war, destroy, and cause trouble on the earth. Their spirits take no food, but do not hunger or thirst. They cause offences but are not seen. And these spirits shall rise up against the children of men and against the women, because they have proceeded from them in the days of the slaughter and destruction.
                And at the death of the giants, spirits will go out and shall destroy without incurring judgment. Coming from their bodies, their flesh shall be destroy until the day of the consummation, the great judgment in which the age shall be consummated, over the Watchers and the godless, and shall be wholly consummated.
                These evil spirits shall torment men without restraint, inhabiting animals and possessing men until the days of the Messiah come.
                And now as to the Watchers who have sent you to intercede for them, who had been in heaven before, (Say to them), “You were in heaven, but all the mysteries of heaven had not been revealed to you, and you knew worthless ones, and these in the hardness of your hearts you have made known to the women, and through these mysteries women and men work much evil on earth.”
    Say to them therefore, “You have no peace.” The
