Encoh prophesied the flood, and told of it being the first, total consumation of sin on earth, and Enoch told of it as an example of the second, greater, consumation of sin on earth, which is yet to come, and is called the Tribulation, in Enoch, andis that of which Jesus spoke.
From the book of 1 Enoch, on the flood, when there were disturbances in earth, Noah sought advice from Enoch, who was dwelling in the Garden of Eden, with the Watchers there:
[Chapter 65]
1, 2 And in those days Noah saw the earth that it had sunk down and its destruction was nigh. And he arose from thence and went to the ends of the earth, and cried aloud to his grandfather Enoch: 3 and Noah said three times with an embittered voice: Hear me, hear me, hear me.' And I said unto him: ' Tell me what it is that is falling out on the earth that the earth is in such evil plight 4 and shaken, lest perchance I shall perish with it ? '
And thereupon there was a great commotion , on the earth, and a voice was heard from heaven, and I fell on my face. And Enoch my grandfather came and stood by me, and said unto me: ' Why hast thou cried unto me with a bitter cry and weeping 6 And a command has gone forth from the presence of the Lord concerning those who dwell on the earth that their ruin is accomplished because they have learnt all the secrets of the angels, and all the violence of the Satans, and all their powers -the most secret ones- and all the power of those who practice sorcery, and the power of witchcraft, and the power of those who make molten images 7 for the whole earth: ...
' And after that my grandfather Enoch took hold of me by my hand and raised me up, and said unto me: ' Go, for I have 10 asked the Lord of Spirits as touching this commotion on the earth. And He said unto me: " Because of their unrighteousness their judgement has been determined upon and shall not be withheld by Me for ever. Because of the sorceries which they have searched out and learnt, the earth and those 11 who dwell upon it shall be destroyed." And these-they have no place of repentance for ever, because they have shown them what was hidden, and they are the damned: but as for thee, my son, the Lord of Spirits knows that thou art pure, and guiltless of this reproach concerning the secrets.
12 And He has destined thy name to be among the holy,
And will preserve thee amongst those who dwell on the earth,
And has destined thy righteous seed both for kingship and for great honours,
And from thy seed shall proceed a fountain of the righteous and holy without number for ever.
[Chapter 66]
1 And after that he showed me the angels of punishment who are prepared to come and let loose all the powers of the waters which are beneath in the earth in order to bring judgement and destruction 2 on all who [abide and] dwell on the earth. And the Lord of Spirits gave commandment to the angels who were going forth, that they should not cause the waters to rise but should hold them 3 in check; for those angels were over the powers of the waters. And I went away from the presence of Enoch.
[Chapter 91]
1 And now, my son Methuselah, call to me all thy brothers
And gather together to me all the sons of thy mother;
For the word calls me,
And the spirit is poured out upon me,
That I may show you everything
That shall befall you for ever.'
2 And there upon Methuselah went and summoned to him all his brothers and assembled his relatives.
3 And he spake unto all the children of righteousness and said:
'Hear, ye sons of Enoch, all the words of your father,
And hearken aright to the voice of my mouth;
For I exhort you and say unto you, beloved:
4 Love uprightness and walk therein.
And draw not nigh to uprightness with a double heart,
And associate not with those of a double heart,
But walk in righteousness, my sons.
And it shall guide you on good paths,
And righteousness shall be your companion.
5 For I know that violence must increase on the earth,
And a great chastisement be executed on the earth,
And all unrighteousness come to an end:
Yea, it shall be cut off from its roots,
And its whole structure be destroyed.
6 And unrighteousness shall again be consummated on the earth,
And all the deeds of unrighteousness and of violence
And transgression shall prevail in a twofold degree.
7 And when sin and unrighteousness and blasphemy
And violence in all kinds of deeds increase,
And apostasy and transgression and uncleanness increase,
A great chastisement shall come from heaven upon all these,
And the holy Lord will come forth with wrath and chastisement
To execute judgement on earth.
8 In those days violence shall be cut off from its roots,
And the roots of unrighteousness together with deceit,
And they shall be destroyed from under heaven.
9 And all the idols of the heathen shall be abandoned,
And the temples burned with fire,
And they shall remove them from the whole earth,
And they (i.e. the heathen) shall be cast into the judgement of fire,
And shall perish in wrath and in grievous judgement for ever.
10 And the righteous shall arise from their sleep,
And wisdom shall arise and be given unto them.
And after that the roots of unrighteousness shall be cut off, and the sinners shall be destroyed by the sword . . . shall be cut off from the blasphemers in every place, and those who plan violence and those who commit blasphemy shall perish by the sword.]
18 And now I tell you, my sons, and show you
The paths of righteousness and the paths of violence.
Yea, I will show them to you again
That ye may know what will come to pass.
19 And now, hearken unto me, my sons,
And walk in the paths of righteousness,
And walk not in the paths of violence;
For all who walk in the paths of unrighteousness shall perish for ever.'
