Enoch - We don't know a lot about Enoch. But, it is my view, that he was one of the two godliest men of the pre-flood era. Noah was one of those two men. And we are told in 2 Peter 2:5, that he was a "preacher of righteousness," back before the flood came. As such, Noah was sort of like, the John the Baptist of the Old World. In Matthew 3:2, we are told John preached, "Repent, for the Kingdom of heaven is at hand". But Noah preached, “Repent, for the Judgment of God, is at hand.” Mark 1:4 says, John the Baptist preached, “Repent, and be Baptized". But Noah preached, "Repent or be baptized permanently."
But, if Noah was the John the Baptist of the Old World, then Enoch was the Elijah of the Old World. And like Enoch, Elijah was also, "translated" straight from the earth to heaven, never to experience death!
“And all the days of Enoch were three hundred sixty and five years: And Enoch walked with God: and he was not; for God took him.” Genesis 5:23- 24
“By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.” Hebrews 11:5
What a testimony! So, Enoch and Elijah, were the only two people on earth, who ever lived, to have experienced such a privilege. So, to say Enoch was a special man, I think is quite an understatement. And as an afterthought here, Enoch's translation up to heaven is a picture of the Rapture of the church, before God's coming judgment on this earth during the Great Tribulation. So, also, Noah's Ark is a picture of God carrying Israel through the Great Tribulation, and preserving his people, through the coming judgment of this world.
And apparently, Enoch was preaching the same repentance message Noah preached before God carried Enoch away leaving Noah as the only real messenger of God to close out the dispensation of the world which then was.
Also, apparently, Enoch wrote a book of messages, and of prophecies, to the people who were then on the earth in his day telling them of things yet to come warning them to repent and to turn from their wicked ways. So, in Enoch's book, we see how God revealed Himself to the Old World, through His Word, much like he has done through our Bible of this current age.
There is a book called, The Book of Enoch in the Apocrypha. But, I believe it is a counterfeit because like the rest of the Apocryphal books, it simply does not measure up to the standards of the accepted canon of the divinely inspired scriptures.
Taking a cursory look at the text up through Chapter 59, I found the following false doctrines. (I may be off on one here or there, but it should be sufficient to get my point across.)
1:1 Implies restoration during tribulation - not congruent with scriptures.
1:8 In conflict with the doctrine that peace was made at the cross. Also, in the last days tribulation will increase for the righteous - this "verse" seems to dispute that.
2:2-3 Appears to contradict 2 Pet 3:3-7
5:4 Is an admonition to some unknown party - this is very irregular relative to the scriptures (i.e. authentic ancient writings by God-fearing Jews)
6:3 Semjaza seems to be listed as the leader of the angels, which is not scriptural
6:3,8 None of these angels are mentioned in the Bible
8:1 Azazel isn't even listed in 6:8 as one of the angels that fornicated with women
8:3 Araqiel and Shamsiel aren't listed in 6:8 either
10:2 Enoch allegedly wrote about Noah, even though the Bible teaches that Enoch was taken up to heaven years before Noah was born.
10:4-6,12 Implies angels can be bound & hid in holes under rocks. This is contrary to scripture.
10:8 Ascribes all the sin of the fallen angels to one named Azazel - not scriptural.
10:15-11:2 Seems to imply that permanent restoration took place after the flood - clearly not true. It seems the true author of this book confused scriptures pertaining to the future restoration.
13:5-6,14:4-5,7 Implies fallen angels can't talk to God - this contradicts Job. Also implies that angels were repentant, but weren't received back by God - very strange doctrine.
14 Gives a very strange description of Heaven that conflicts with many scriptures
15:8-10 Very strange doctrine about "evil spirits" proceeding from unredeemable giants
17-18,21,23 Gives a very strange description of the earth & universe which is clearly not true. Also alludes to the ancient model of astronomy that held that there were 7 stars (the closest planets) which burned like the sun (they don't.)
19:3 Discredits all other prophecies about the consummation of the ages.
20 Lists strange angels not in scripture, and incorrectly assigns the roles of Michael (the warrior) and Gabriel (the messenger)
21:7-10 Seems to contradict Biblical descriptions of the present & final judgment places for the fallen angels
22 Contradicts the Biblical descriptions of past, present & future dwelling places for the righteous who die
32:2-6 Seems to imply the Garden of Eden was still in existence after the Flood
33:1-2 Says Heaven rests on a foundation that is at the Eastern edge of the earth
33:3 He claims he counted the stars & individually mapped them, which is impossible scripturally (& scientifically)
34 Says the winds come out of a "portal" at the Northern edge of the earth
36:3 Says the stars come out of portals at the Eastern edge of the earth & move West
38:5-6 Contradicts Daniel & other prophecies about the Millennial Reign
39:1-2 Very strange implications here about the "seed" of angels dwelling with men at the end... this contradicts the scriptures
40:7 Talks about the "Satans" - plural, different than the Bible, who gives that name to only one fallen angel. Also, implies Satan can't stand in God's presence, contrary to Job.
40:9 Once again mixes up the roles of the 2 Archangels & adds more names. Michael's role in scripture is related to conquering nations & fighting spiritual wars, while Gabriel's relates to bringing messages & visions to people.
41:1-2 Says the Kingdom of God is divided - it's not & can't be scriptural. Also describes sinners being repelled from a mansion, which is also not scriptural, unless you look at a parable Jesus told, which was not intended to be literal.
41:4-5 Says the sun, moon, winds, etc. are stored in chambers & released at appointed times.
41:6-7 Implies the sun & moon move opposite of each other
43:1-3,44 Very weird model of the nature of stars & lightning
47:4 Says God requires the blood of the saints... very strange
51:1 Says Sheol & Hell will give back to the earth, which isn't scriptural - also Hell is an NT term, not OT
51:2 Disputes the Biblical doctrine that we are chosen. (We don't have to wait until Christ's return to be chosen.) This isn't scriptural.
General: Seems to imply Enoch came back down to earth after being taken up to Heaven, which is not scriptural.

However, we do not know what became of the authentic Book of Enoch. It may have perished in the flood. Noah may have had a copy of it on his Ark, but we simply do not know. But, apparently, if Noah took any books or manuscripts onto the ark, they have either perished through time or, they are hidden away somewhere waiting to be revealed perhaps during the Great Tribulation.
There is a theory, or a rumor, that many of those ancient writings, along with the ashes of the Red Heifer, and the Ark of the Covenant, are hidden somewhere beneath the Temple Mount, which would mean currently under the Dome of the Rock mosque.
And this theory seems like a plausible one to me. Because the ashes of the Red Heifer, and the Ark of the Covenant, must be found, in order to validate the coming Tribulation Temple, which we are told will be rebuilt in Jerusalem, during the Great Tribulation. But that is a rabbit I need to stop chasing, here and now!
So, the only thing we really know about Enoch's prophecies is given to us in what I think is one of the most remarkable books in the Bible, which is, the little one chapter, Book of Jude.
