Here is the scriptural account...
1 Now the serpent [Satan
having come down in human form and seducing Eve using the tactics of a snake]
proved to be the most cautious of all the wild beasts of the field [he
became the most cunning of the angels who reject outright God's authority]
that Jehovah God had made. So it began to say to the woman [Eve]:
Is it really so that God said you must not eat from every tree of the garden?
2 At this the woman said to the serpent: Of the fruit of the trees of the garden we may eat.
3 But as for [eating] of the fruit of the tree that is in the middle of the garden, God has said, 'You must not eat from it, no, you must not touch it that you do not die.'
4 At this the serpent said to the woman: You [plural] positively will not die.
5 For God knows that in the very day of your eating from it your eyes are bound to be opened and you are bound to be like God, knowing good and bad.
6 Consequently the woman saw that the tree was good for food [the literal tree and tasty literal food upon it] and that it was something to be longed for to the eyes [the tree and its fruit were good looking], yes, the tree was desirable to gain wisdom [literally eating would give her wisdom] [lykXh]. So she began taking of its fruit and eating it. Afterward she gave some also to her husband when with her and he began eating it.
7 Then the eyes of both of them became opened [they understood the game that Satan had played with them and they woke up sexually too] and they began to realize that they were naked [both physically, since they had discovered the power of the lower regions and spiritually since they began to appreciate their moral naivety]. Hence they sewed fig leaves together and made loin coverings for themselves (Genesis 3).
43 Why is it you do not know what I am
speaking? Because you cannot listen to my word.
44 you are from your father the Devil, and you wish to do the desires of your father. That one was a manslayer [he did not murder Eve because she also had an angelic body. He did kill her human body, so he was a manslayer] when he began, and he did not stand fast in the truth, because truth is not in him [although he was in the truth until he turned to the lie]. When he speaks the lie, he speaks according to his own disposition, because he is a liar and the father of [the lie] (John 8).
Now the trees in the garden were real trees and Eve was a real woman. But the snake was plainly not a real snake because real snakes cannot talk or have sex with human women. The first naive solution to this problem is to say that the snake was used as a ventriloquists dummy by Satan. But the Gnostic writing below shows that Satan committed adultery with Eve, something that he could not have achieved as a snake. Furthermore Eve declaring that she had produced Cain with Jehovah and not with Adam, and Cain not being Adam's seed but Abel being such confirms that Cain was a physical son of Satan, begotten by Satan and Eve.
1 And the man knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man with [the help of] Jehovah. (Genesis 4 ASV)
1 Now Adam had intercourse with Eve his wife and she became pregnant. In time she gave birth to Cain and said: I have produced a man with the aid of Jehovah. (Genesis 4 NWT)
1 And the man knew Eve his wife, and she conceiveth and beareth Cain, and saith, 'I have gotten a man by Jehovah;' (Genesis 4 YLT)
The words 'the aid of' are added in the NWT as the ASV correctly indicates. The YLT even more correctly just omits them. Jehovah turned on her reproductive organs so that she could procreate sexually (something that pre-adamics could not do). But there is more... Satan was the mediator of the first holy spirit covenant. He was the head of God's first wife. He therefore was God's flesh. So he firstly committed adultery with Eve (being married directly to Jehovah). He secondly committed bestiality with Eve, since she was a lower life form than him. Then he further caused God's flesh to commit incest and adultery. So he not only defiled God's flesh, but also broke pretty much every rule in the book of Moses by that one act.
Here is some extra information from the Gospel of Philip (a Gnostic text)...
He who has been created is beautiful [any angelic birth, any child born to judicially living parents], but you would <not> find his sons [begotten sons such as the Nephilim, produced not angelically but by sexual reproduction] noble creations. If he were not created, but begotten [by sexual reproduction], you would find that his seed was noble [Abraham was begotten and his seed is noble]. But now he was created (and) he begot [Satan was created angelically and he had sex with Eve. He did what the demons later did with human women. Eve could only beget after she sinned, since begetting by sexual reproduction is the preserve of the dead. God allows people to have children without his consent only if these children are dead. So first Satan enticed Eve to sin and die as a human (start ageing) but not as an angel. Then he slept with her and made her pregnant then he conspired with her to murder Adam who lost his human soul and his angelic soul. Eve never lost her angelic soul and so was not murdered, although she did lose her human soul. Actually Eve did not die, she was raptured when her human body gave out, since she had an angelic soul and was not baptized into a covenant that required death]. What nobility is this? First, adultery came into being, afterward murder [Satan first seduced Eve and committed adultery with her not because she was married to or engaged to Adam, but because he was married to God as the mediator of the 1HSC]. And he [Cain] was begotten in adultery, for he was the child of the Serpent [Satan came down in human form to seduce Eve, and Cain was carried and delivered by Eve]. So he became a murderer/manslayer, just like his father, and he killed his brother [Abel]. Indeed, every act of sexual intercourse which has occurred between those unlike one another is 'adultery'/necrozoan bestiality [Satan mating with Eve was adultery and was bestiality. It was also a living being having illegal procreative sex with a dead being. The dead beget within marriage, the living create within a child rearing agreement. The two should not cross fertilise each other]. (Gospel of Philip - gnostic writings)
Angels are created by divine consent. Humans are begotten by mutual consent and by sexual reproduction. When a created being begets i.e. has sex with a ageing human, he commits bestiality. Satan seduced Eve for Cain. The demons seduced any other women they fancied for the Nephilim. Cain and the Nephilim were all murderers.
Now human marriage is an institution for the dead, so Adam and Eve were not married in the garden, and actually they could not have procreated in the garden they could only have created a child on God's behalf since both were living. So Satan did not sin against Adam in adultery, but he did sin against the first holy spirit covenant which he mediated. So he was unfaithful as God's wife. That was his adultery. This actually destroyed the first holy spirit covenant and God lost his first wife as so many humans do today.
He also committed what we call necrozoan bestiality with Eve, since he was judicially living and she was judicially dead as a human at the time that they begat Cain, and the living should not beget, they must create on behalf of God.
This of course was the great attraction to Satan. He was not interested in giving God any more children, he wanted children of his own, to whom he could be God. So he needed Eve to sin in order that she would be able to beget, to procreate without a consent being required from an angelic priesthood. Satan would then become the father of a human race through Cain, rather than God being their father through Adam. So he persuaded Eve to sin, then he persuaded her to sleep with him, and then she persuaded Adam to sin by sleeping with her.
So Satan began as an adulterer and as a manslayer of Eve, not a murderer of her, since he killed her human body but she had a second angelic body at her disposal. And he began as a liar, telling her that 'they' would not die. Actually Eve did not die judicially since she had no idea that she was committing adultery and since she was deceived by Satan who lied to her.
44 you are from your father the Devil, and you wish to do the desires of your father. That one was a manslayer when he began, and he did not stand fast in the truth, because truth is not in him. When he speaks the lie, he speaks according to his own disposition, because he is a liar and the father of [the lie] (John 8).
14 Also, Adam was not deceived, but the woman was thoroughly deceived and came to be in transgression (1 Timothy 2).
Eve herself was only under the law of do not eat from the tree, so she was not guilty of adultery. Her law did not say do not sleep with angles in humans acting like snakes! And in any event she had no idea what adultery was since marriage had not yet ever occurred since no human had yet died judicially. So she was absolutely nowhere with this stuff, and must have been well surprised when she discovered that sex lead to pregnancy, something that was not the case with pre-adamics.
But Adam did die in both of his bodies as a result of his sin, so since Satan told Eve that both of them would positively not die, he lied in respect of Adam.
44 you are from your father the Devil, and you wish to do the desires of your father. That one was a manslayer when he began, and he did not stand fast in the truth, because truth is not in him. When he speaks the lie, he speaks according to his own disposition, because he is a liar and the father of [the lie]. (John 8 NWT).
So Satan started as a manslayer of Eve (a womanslayer in fact). He did not murder her since being deceived she did not lose her angelic soul. Then he became a bestial adulterer with Eve with whom he begot Cain, the first Nephilim. Then he conspired with Eve to kill Adam. When Eve went through with Satan's plan for Adam, Satan became his murderer, since he lost both of his souls, because he was not deceived. He knew precisely what he was doing when he sinned.
Now Cain was therefore a cross breed really, the first Nephilim. But he could procreate...
17 And Cain had intercourse with his wife and she became pregnant and gave birth to Enoch. Then he engaged in building a city and called the city's name by the name of his son Enoch. (Genesis 4 NWT).
This brings us nicely to the weird wording of Genesis 6:4...
3 After that Jehovah said: My spirit shall not act toward man indefinitely in that he is also flesh. Accordingly his days shall amount to 120 years.
4 The Nephilim proved to be in the earth in those days, and also after that, when the sons of the [true] God had relations with the daughters of men and they bore sons to them, they were the mighty ones who were of old, the men of fame. (Genesis 6 NWT - corrected from the Hebrew).
3 And Jehovah said, My spirit shall not strive with man for ever, for that he also is flesh: yet shall his days be a hundred and twenty years.
4 The Nephilim were in the earth in those days, and also after that, when the sons of God came unto the daughters of men, and they bare children to them: the same were the mighty men that were of old, the men of renown. (Genesis 6 ASV)
So the Nephilim already existed before the sons (plural) of God came unto the daughters of men. These were the line from Cain, a line of fertile Nephilim. Whereas the second group of Nephilim from materialised demons were infertile being heavenly-earthly cross breeds like the mule. It was Jehovah who made them infertile because they were born from adultery according to the gnostic gospel of Philip. But Genesis 6:4 proves that Cain was Satan's son since the Nephilim (who are the cross breed children of demons and humans) pre-existed the ones produced by the descent of the demons. And Satan was the only descended angel around prior to that. Satan was identical to Adam in human form since they were both direct first generation sons of God. So he could procreate by sexual reproduction with a dead in the flesh Eve, just as Adam could and make fertile children just as Adam did. But the demons who descended and copied the perverted activities of their leader produced infertile Nephilim (presumably God prevented them multiplying and ruining the human line). This brings us nicely to Numbers 13:33 which says...
33 And there we saw the Nephilim, the sons of Anak, who are from the Nephilim; so that we became in our own eyes like grasshoppers, and the same way we became in their eyes. (Numbers 13 NWT)
33 And we saw the giants there, the sons of Anak, of the giants. and we were in our own eyes as grasshoppers, and so we were in their eyes. (Numbers 13 GLT)
33 and there we saw the Nephilim, sons of Anak, of the Nephilim; and we are in our own eyes as grasshoppers; and so we were in their eyes.' (Numbers 13 YLT)
For the grasshopper is a strange metaphor to use for a smallness of size. The locust is know for its ability to swarm and to jump very high and to consume everything. That has been the activity of sexually reproducing mankind. We have swarmed on the planet, we have consumed everything and we have reached for the stars with our machines and our minds. It is as the cryptic masterpiece says...
15 Even there fire will devour you. A sword will cut you off. It will devour you like the locust species. Make yourself heavy in numbers like the locust species; make yourself heavy in numbers like the locust. (Nahum 3 NWT)
The reason that we look like locusts to the Nephilim is that they cannot swarm or make themselves heavy in numbers, because they are infertile mules. Now Anak is said to be the son of Arba the founder of Hebron which used to be named after him as Kiriath Arba
2 So Sarah died in Kiriath-arba, that is to say, Hebron, in the land of Canaan, and Abraham came in to bewail Sarah and to weep over her. (Genesis 23 NWT)
13 And to Caleb the son of Jephunneh he gave a share in the midst of the sons of Judah at the order of Jehovah to Joshua, namely, Kiriath-arba
[meaning the city of Arba, meaning the city of
4 or 4th] the father of Anak, that is to say, Hebron.
14 So Caleb drove away from there the 3 sons of Anak, namely, Sheshai and Ahiman and Talmai, those born of Anak. (Joshua 15 NWT).
10 So Judah marched against the Canaanites who were dwelling in Hebron now the name of Hebron before that was Kiriath-arba, and they went striking down Sheshai and Ahiman and Talmai. (Judges 1 NWT)
So Arba was around at the time of Abraham and was the ancestral father of Anak but not his immediate father. The Anakim were Nephilim. So Anak was possessed (not materialized since he had a human father). Judah killed the 3 sons of Anak. But there still remained some other sons of Anak in Gath and Gaza and Ashdod...
21 Furthermore, at that particular time Joshua went and cut off the Anakim from the mountainous region, from Hebron, from Debir, from Anab and from all the mountainous region of Judah and from all the mountainous region of Israel. Along with their cities Joshua devoted them to destruction.
22 No Anakim were left in the land of the sons of Israel. It was only in Gaza, in Gath and in Ashdod that they remained. (Joshua 11 NWT).
This then was Satan's attempt to do to the post flood system what he did to the pre flood system. He wanted to corrupt the promised land with his awful cross breed sons. But he could not use his edenic human body. He had to possess Anak. Again these angelic human cross breeds were made infertile by God.
