I have looked at the Stack Exchange comments on Genesis 6:4 but have not found the following opinion expressed.
Could someone schooled in Hebrew please comment on my use of the word "Owlam" (Strong's #5769) in this context.
The conclusion that I draw to explain Gen 6:1-4 is that the Demonic Spirits saw that women were fair. The spirits then bore offspring by/through the women.
The offspring or result of the union of a spirit and a human would be a possessed human in Biblical terminology.
The resultant offspring are referred to as Nephilim in some circles and are men or mortals of "Owlam" in Gen 6:4.
(CLV) Gn 6:4 As for the distinguished, they were on earth in those days and also afterward, when the sons of the elohim were coming to the daughters of the human, and they bore them offspring. They were the masterful ones, who were from the eon, mortals of renown.
They were mortals from the eon. Eon is the way the CLV (Concordant Literal Version) chose to translate the Hebrew word “Owlam”. "Owlam" means forever or eternity, and is translated as "of Old" in most versions of the Bible.
I feel that the product of the union between the Sons of God and the Daughters of men were “Men” with eternal spirits inhabiting them.
The word "eternal" is used here to describe the demonic spirits because angels are not subject to death, hence the Demonic spirits were not subject to death either.
This concept is based upon the verse stating that Jesus was made a little lower than the angels for the suffering of death, Heb 2:9.
