Genesis 6:3

And it came to pass when the children of men began to multiply on the face of the earth and daughters were born unto them, that the angels of God saw them on a certain year of this jubilee, that they were beautiful to look …

As long then as there continued that separation of the lines between them, the seed of Seth, as it sprang from an excellent root, was by reason of its sanctity termed "angels of God," or as some copies have it "sons of God;" and on the contrary the others by reason of their own and their fathers' wickedness and their earthly deeds were termed "children of men." Though then there was up to this time that holy and salutary separation between them, yet after this the sons of Seth who were the sons of God saw the daughters of those who were born of the line of Cain, and inflamed with the desire for their beauty took to themselves from them wives who taught their husbands the wickedness of their fathers, and at once led them astray from their innate holiness and the single-mindedness of their forefathers...From these sons of Seth then and daughters of Cain, as we have said, there were I born still worse children who became mighty hunters, violent and most fierce men who were termed giants by reason of the size of their bodies and their cruelty and wickedness. For these first began to harass their neighbours and to practise pillaging among men, getting their living rather by rapine than by being contented with the sweat and labour of toil, and their wickedness increased to such a pitch that the world could only be purified by the flood and deluge.

God, when He had made the whole world, and subjected things earthly to man, and arranged the heavenly elements for the increase of fruits and rotation of the seasons, and appointed this divine law-for these things also He evidently made for man-committed the care of men and of all things under heaven to angels whom He appointed over them. But the angels transgressed this appointment, and were captivated by love of women, and begat children who are those that are called demons; and besides, they afterwards subdued the human race to themselves, partly by magical writings, and partly by fears and the punishments they occasioned, and partly by teaching them to offer sacrifices, and incense, and libations, of which things they stood in need after they were enslaved by lustful passions; and among men they sowed murders, wars, adulteries, intemperate deeds, and all wickedness. Whence also the poets and mythologists, not knowing that it was the angels and those demons who had been begotten by them that did these things to men, and women, and cities, and nations, which they related, ascribed them to god himself, and to those who were accounted to be his very offspring, and to the offspring of those who were called his brother), Neptune and Pluto, and to the children again of these their offspring. For whatever name each of the angels had given to himself and his children, by that name they called them.

And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters.

When men multiplied on the earth, the angels of heaven came together with the daughters of men. In some copies I found "the sons of God."

(Version 3.) And the Lord God said: My spirit will not dwell in these men forever, because they are flesh. In Hebrew, it is written, My spirit will not judge these men forever, because they are flesh: that is, because the condition of man is fragile, I will not subject them to eternal torment; but here I will restore to them what they deserve. Therefore, it signifies not severity, as it is read in our codices, but rather the mercy of God, while the sinner is visited here for his crime. And an angry God speaks to some: I will not visit their daughters, when they have fornicated, and their wives, when they have committed adultery (Hosea IV, 14). And in another place: I will visit their iniquities with a rod, and their sins with scourges: nevertheless, I will not take away my mercy from them (Ps. LXXXVIII, 33). Furthermore, so that it does not appear cruel on His part for not giving a place of repentance to sinners, He added: But their days shall be one hundred and twenty years. This is, they will have 120 years to do penance. Therefore, human life, as many err, is not condensed into 120 years: but to that generation, 120 years were given for penance. For we find that after the flood, Abraham lived for 175 years, and others for over 200 and 300 years. But because they refused to do penance, God did not want to wait for the appointed time: but with 20 years cut off, He brought about the flood in the 100th year designated for doing penance.

By the justice of God in some sense, the human race was delivered into the power of the devil; the sin of the first man passing over originally into all of both sexes in their birth through conjugal union, and the debt of our first parents binding their whole posterity. This delivering up is first signified in Genesis, where, when it had been said to the serpent, "Dust shalt thou eat," it was said to the man, "Dust thou art, and unto dust thou shall return." In the words, "Unto dust shalt thou return," the death of the body is fore-announced, because he would not have experienced that either, if he had continued to the end upright as he was made; but in that it is said to him whilst still living, "Dust thou art," it is shown that the whole man was changed for the worse. For "Dust thou art" is much the same as, "My spirit shall not always remain in these men, for that they also are flesh." Therefore it was at that time shown, that he was delivered to him, in that it had been said to him, "Dust shall thou eat."

And God said, "My Spirit shall not remain in man forever, because he is flesh; and his days shall be one hundred and twenty years."

Justice said, Cut them down; but mercy interceded, Lord, let them alone this year also; and so far mercy prevailed, that a reprieve was obtained for six-score years. Note, The time of God's patience and forbearance towards provoking sinners is sometimes long, but always limited: reprieves are not pardons; though God bear a great while, he will not bear always.

My spirit shall not always strive - It is only by the influence of the Spirit of God that the carnal mind can be subdued and destroyed; but those who wilfully resist and grieve that Spirit must be ultimately left to the hardness and blindness of their own hearts, if they do not repent and turn to God. God delights in mercy, and therefore a gracious warning is given.

Some authorities suggest that this might be an allusion to the Sons of God who came down to corrupt the daughters of men, resulting in the Nephilim (Fallen Ones) of Genesis 6.
