Genesis 6:5

After Moses spoke about the mighty men who were born into the tribe of Cain, whose women, even though beautiful, were nevertheless smaller than the sons of Seth, he then said, "The Lord saw that the wickedness of man was great in the earth and that every inclination of the thoughts of his heart was always evil," for in the years given to them for repentance they had increased their sins. "The wickedness of mankind was great in the earth," that is, evil extended and spread throughout both those tribes. "The inclination of the thoughts of their hearts was always evil," for their sins were not committed only occasionally, but their sins were incessant. Night and day they would not desist from their wicked thoughts.

But God, seeing that the wickedness of men was great on the earth, and that every thought of their hearts was only evil continually, regretted that He had made man on the earth. He is said to have regretted, not because God, like man, truly regrets any of His actions, whose judgment on all things is as fixed as His foreknowledge is certain; but Scripture uses such words in order to insinuate itself to us more familiarly, we who are accustomed to change anything we undertake and transfer it into something else only by repenting: even though divine providence, for those perceiving with a serene mind, appears to administer all things with the most certain order. Nevertheless, Scripture fits and adapts itself to the humble understanding of the slower minds, of whom the far greater number is, so that it says as if by the repentance of God, those things taken away which begin to exist, and do not continue as long as they were hoped to last: similar to which is what follows.

And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed upon the earth, and all lawlessness being wrought upon the earth. And they said one to another: 'The earth made without inhabitant cries the voice of their cryingst up to the gates of heaven. And now to you, the holy ones of heaven, the souls of men make their suit, saying, "Bring our cause before the Most High."' And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Thy glory (standeth) unto all the generations of the ages, and Thy name holy and glorious and blessed unto all the ages! Thou hast made all things, and power over all things hast Thou: and all things are naked and open in Thy sight, and Thou seest all things, and nothing can hide itself from Thee. Thou seest what Azazel hath done, who hath taught all unrighteousness on earth and revealed the eternal secrets which were (preserved) in heaven, which men were striving to learn: And Semjaza, to whom Thou hast given authority to bear rule over his associates. And they have gone to the daughters of men upon the earth, and have slept with the women, and have defiled themselves, and revealed to them all kinds of sins. And the women have borne giants, and the whole earth has thereby been filled with blood and unrighteousness. And now, behold, the souls of those who have died are crying and making their suit to the gates of heaven, and their lamentations have ascended: and cannot cease because of the lawless deeds which are wrought on the earth. And Thou knowest all things before they come to pass, and Thou seest these things and Thou dost suffer them, and Thou dost not say to us what we are to do to them in regard to these.' Then said the Most High, the Holy and Great One spake, and sent Uriel to the son of Lamech, and said to him: 'Go to Noah and tell him in my name "Hide thyself!" and reveal to him the end that is approaching: that the whole earth will be destroyed, and a deluge is about to come upon the whole earth, and will destroy all that is on it. And now instruct him that he may escape and his seed may be preserved for all the generations of the world.' And again the Lord said to Raphael: 'Bind Azazel hand and foot, and cast him into the darkness: and make an opening in the desert, which is in Dudael, and cast him therein. And place…
