1 And Uri’el said to me: 'Here shall stand the angels who have connected themselves with women, and their spirits assuming many different forms are defiling mankind and shall lead them astray into sacrificing to demons as gods, (here shall they stand,) till the day of the great judgment in which they shall be judged till they are made an end of.
2 And the women also of the angels who went astray shall become sirens.'
3 And I, Chanoch, alone saw the vision, the ends of all things: and no man shall see as I have seen
29 And Yeshua answered and said to them, "You do err, not knowing the Scriptures, nor the power of Elohim.
30 For in the resurrection they marry not, neither are they betrothed, but are as the angels of Elohim in heaven.
I submit to you that just because there are male and female, does not mean there is marriage in the kingdom or in the resurrection. Yeshuah gave no indication of gender neutrality, but gave an explanation of a social state within the Kingdom which is different for those having immortal life or life that can extend for thousands of years. Chanoch, in verse 2, identified that there were female watchers as well as the males identified in verse 1. The punishment for the females was a little different but not substantially so, as both are pending the time of their final judgement. This further supports the ideas of the genetic blending that Jasher and Enoch describe, and Genesis appears to elude to. So Yeshua's statement about marriage in the Kingdom may have no relevance as to the existance of male and female gender among angels (watchers), this is a filter we put on in our limited concepts of culture. It is important to remember that animals are male and female and are not given or taken in marriage (Taking on a life partner) for the most part.
Bereshit (Genesis) 1:
27 And Elohim created man in His own image, in the image of Elohim created He him; male and female created He them.
Even in Genesis, mankind is made after the image of Elohim - male and female.
Although many do not believe that a second incursion has occurred or will, but rather believe the same net effect comes about through other means (Genetic manipulation). I am not shutting out that possibility. There appears to be some scriptural evidence that a second incursion (post-flood) may have occurred:
Bereshit (Genesis) 6:
4 The N’filim were on the earth in those days, and also after that, when the sons of Elohim (B'nai Elohim) came in unto the daughters of men, and they bore children to them; the same were the mighty men that were of old, the men of renown.
A plain reading of the above indicates that the B'nay Elohim, a term consistently used to refer to the angels, came to the daughters of men during the antideluvian era, and after that... Implying that they did it at least twice and that their offspring were mighty men. In mythology they would be Titans, or sons of the gods - people like Hercules, Daphne, Peneus, Achilles, and many others.
6 And the angels who did not keep their first estate, but left their own habitation, He has reserved in everlasting chains under darkness for the judgment of the great day;
7 as S’dom and ‘Amora and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.
In the above passage, the sins of the fallen angels (Watchers) are referenced, and notice that the sins of S'dom and 'Amora are equivocated? Both are as going after "strange flesh" or flesh which is not their natural desire for procreation. This may have been why the two angels that went to see Lot were so attractive to these people, they were two angels which were new to them. This lusting for relations with angels was all they needed to confirm that the there was indeed a genetic contamination in these cities that needed to be purged. Notice that in preceding verses in Genesis regarding Lot that he, nor his family, had not been raped or attacked by the citizens of the city, neither was Abraham - before or after his rescue of Lot - or any of his household. Abraham didn't even appear to have a direct issue with the people of those cities but was instead trying to negotiate on their behalf with those that had recently attacked them. This tells me that our understanding of the sins of those cities may not be as we have been taught or assumed. We must remain open to other understandings - especially as new information is uncovered, or old information is identified as being related, as in Genesis, Jude, and Chanoch.
You may ask, "why is this important?"
37 And as it was in the days of Noach, so will it be at the coming of the Son of Man.
We know from this passage in Matthew that when the Messiah comes, it will be like it was in the days of Noach. We know from the previous passages documenting these incidents and events that the information is important to future generations. We also know from Chanoch's testimony that the information is being transferred to the generation of the end of days for a reason. We see genetic modifications taking place in plants and animals by our modern science. We see attempts at cloning and blending of species. The side effects and outcomes of these experiments are unpredictable as we barely understand the genomes that are being manipulated. We hear stories of interactions with beings that are "alien". All these things tie together and when ancient myth is placed in a modern context we can see a direct relationship between those myths and Biblical history, and a tie to practices and events that are ocurring today. It is important to know and understand these things as they tell us of the times we live in. That understanding helps us to prepare on a physical and spiritual level for the time of tribulation.
