The Nephilim
In order to properly gain an understanding of the events that take place in Genesis 6 just prior to the flood, We must understand the direct context surrounding the event.
Gen 1 and 2 we have the creation of the world and how it is very good in the eyes of God.
Gen 3 shows how Satan deceived Eve and thus the fall of the human race.
Gen 4 shows us the line of Cain through his descendants. Cain was not a follower of God and this is seen
through his actions. when God tried to warn Cain about his anger, Cain did not listen and killed his
brother Abel. When God punished Cain for this sin, Cain's response was to leave God altogether.
Gen 4:16 And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.
Gen 5 We have the line of Seth through Adam.
It's important then to note that the bible has made or distinguished between two groups of people on the earth. We have the line of Cain which turned from God and the line of Seth which followed God.
Let us now examine Genesis 6.
Gen 6:1 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
Let's ask ourselves, when did men begin to multiply?
We just read in chapter 4 and 5 the multiplication through the lines of Cain and Seth. but here it says that Daughters were born unto them.
Lets note a few things here. If you go and check the lines of Cain and the lines of Seth you will notice that only in the line of Cain are women mentioned. In fact the Line of Cain ends with a daughter named, Naamah.
Now this is not to say that no women or daughters were born in Seth's line, but we are now seeing the reason that women and finally a daughter are mentioned in Cain's line. This directly links the term Man in verse 1 to the line of Cain.
Men simply means mankind, and one might argue that even Seth's line was included here. the issue with that is even Noah as we will see later is excluded from this term as it is used in this chapter. Otherwise Noah would have been destroyed also. so the term mankind is deliberately used here to refer to the line of Cain.
Gen 6:2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
Notice now that the "sons of God" saw the Daughters of men. Again we know who the daughters of men are and they are not Seth's Daughters but Cain's.
Here is another issue with this passage. The expression here is not just have sex with them, but took them as partners. the issue is also that they took wives plural. Polygamy. this polygamy first showed its face where? In the line of Cain through Lamech. Again a direct link to the line of Cain and a learned evil from the line of Cain.
Could these sons of God be angels? the short answer is no. there are a number of problems with this view. Genesis has set us up with two lines. those who follow God/sons of God and those who do not follow God/men and daughters of men. Gen 6 we can see connects the men and daughters of men directly to the line of Cain. thus it is only logical and contextually sound that the sons of God are referring to the line of Seth who followed God.
This is backed by the numerous bible examples of those who follow God as being children of God, sons of God.
also we have two lines one uses female/Cain the other only male/Seth. two are seen in chapter 6, sons/male and daughters/female.
The other issue is that Jesus himself said that Angels do not marry/take wives.
Mat 22:30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
So here we have Gods people marrying women who do not follow God and also taking up their practice of polygamy. So Gods people are being influenced by evil.
Gen 6:3 And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
Notice that God says he will not strive with man, yet he did with Noah and Noah was a man. thus Man again is used in a specific way. it refers to the line of Cain who did evil and also any of Seth's line that would do evil because of their unholy union. It is pertinent to note that Gods issue here is with humanity there is no mention of angels here at all. on top of that why did Moses not use the word for angels if that was indeed the intent here. Some may say it's symbolic, then one would have to ask the question why when this clearly is not that important to know. symbols were used by God to teach important lessons that needed to be understood.
Gen 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
Now we have already been told in verse 2 that they did not simply have sex but actually took them as wives. this is a human relation that is forbidden by God. (Deut 7:3,4; Joshua 23:12,13; Ezra 9:2; Neh 13:25; 2 Cor 6:14,15).
Giants what does this mean? Many interoperate this to mean large in stature. while this can be one of the meanings applied it is less forceful in this case do to the fact that everyone was a giant in size at this time. this word has another meaning that fits the passage more fully, it means to be violent in nature. bullies etc. thus it is here a characteristic of their characters not there physical stature. (Patriarchs and Prophets show this same thing.)
This fits with verse 11 which confirms this interpretation.
Gen 6:11 The earth also was corrupt before God, and the earth was filled with violence.
Gen 6:12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.
notice again the issue is with flesh/humans not angels. there is no hint at all that these men are anything other than men.
Gen 6:5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
notice again that the issue is that their thoughts are evil all the time. thus again it is a characteristic of the people that causes the evil which God wishes to destroy.
Gen 6:6 And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
Gen 6:7 And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
Notice again that the Lord is upset that he made man on the earth. these are people that God has created. they are not some freak almost evolutionary being. They were knit in the womb by God. however the word again is mankind used here, yet even though Noah was a human he followed God and thus was not included in this description of destruction to come.
Gen 6:12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.
Gen 6:13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
God is going to destroy all flesh/humans who are evil. the flood was to destroy the people who had done these things. or as we discovered in the first few verses. the Flood was to destroy Cain's line and all those who joined with it and became evil because of this union.
In fact lets add one more bit of information to clarify this point.
We have two lines, one from Adam through Seth and another from Adam through Cain.
Did you know that from this point Cain's line disappears? After the flood Cain's line is gone but Seth's continues all the way down to Jesus.
Luk 3:23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,
Luk 3:24 Which was the son of Matthat, which was the son of Levi, which was the son of Melchi, which was the son of Janna, which was the son of Joseph,
Luk 3:25 Which was the son of Mattathias, which was the son of Amos, which was the son of Naum, which was the son of Esli, which was the son of Nagge,
Luk 3:26 Which was the son of Maath, which was the son of Mattathias, which was the son of Semei, which was the son of Joseph, which was the son of Juda,
Luk 3:27 Which was the son of Joanna, which was the son of Rhesa, which was the son of Zorobabel, which was the son of Salathiel, which was the son of Neri,
Luk 3:28 Which was the son of Melchi, which was the son of Addi, which was the son of Cosam, which was the son of Elmodam, which was the son of Er,
Luk 3:29 Which was the son of Jose, which was the son of Eliezer, which was the son of Jorim, which was the son of Matthat, which was the son of Levi,
Luk 3:30 Which was the son of Simeon, which was the son of Juda, which was the son of Joseph, which was the son of Jonan, which was the son of Eliakim,
Luk 3:31 Which was the son of Melea, which was the son of Menan, which was the son of Mattatha, which was the son of Nathan, which was the son of David,
Luk 3:32 Which was the son of Jesse, which was the son of Obed, which was the son of Booz, which was the son of Salmon, which was the son of Naasson,
Luk 3:33 Which was the son of Aminadab, which was the son of Aram, which was the son of Esrom, which was the son of Phares, which was the son of Juda,
Luk 3:34 Which was the son of Jacob, which was the son of Isaac, which was the son of Abraham, which was the son of Thara, which was the son of Nachor,
Luk 3:35 Which was the son of Saruch, which was the son of Ragau, which was the son of Phalec, which was the son of Heber, which was the son of Sala,
Luk 3:36 Which was the son of Cainan, which was the son of Arphaxad, which was the son of Sem, which was the son of Noe, which was the son of Lamech,
Luk 3:37 Which was the son of Mathusala, which was the son of Enoch, which was the son of Jared, which was the son of Maleleel, which was the son of Cainan,
Luk 3:38 Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the son of God.
There is no mention of Cain's line after the flood, it is cut off. yet Seth's line continued. but another important piece of information is that here Adam is called the son of God. Thus it is accurate that the line of Adam through Seth refer to the sons of God, those who followed God.
The Flood did exactly what God intended to do, to wipe the line of Cain out altogether. and all who perverted their ways with the Canaanites. blessings.
