Hello Apostolicman,
Most English versions of the Bible do not attempt to translate, but rather transliterate "Nephilim" from the Hebrew נְפִילִים because its meaning is uncertain. The KJV renders it "giants," probably because of the description in Numbers 13:33, but the language of Genesis 6:4 indicates that the offspring of "the sons of God" and "the daughters of men" were mortal men. They were "famous
men" (NET) or "
men of renown" (KJV, ASV, RSV, ESV), and the Hebrew word for men, אנושׁ (
enosh), in Genesis 6:4 properly means
mortals. That means the offspring were not angels.
These men were apparently all destroyed in the flood (Gen 7:21-23; 1 Pet 3:20). As the meaning of "Nephilim" is uncertain, the term could be descriptive--meaning something like 'mighty' or 'powerful'--rather than being a designation for a race of super beings (assuming that the sons of God in Genesis 6:4 were angels). If that is the case, the perceived observation of Nephilim in Numbers 13:33 does not mean that the offspring identified as Nephilim in Genesis 6:4 survived the flood. The Nephilim of Numbers 13 may have been so described simply because they were big and powerful. It's also possible that the Israelite spies figuratively identified the giants whom they saw in Canaan with the antediluvian Nephilim because of their large size even though there was no biological connection. But the Bible is clear that only Noah and his family (including his sons' wives) survived the flood and it is improbable that any of them were Nephilim, particularly since the Nephilim were associated in Genesis 6 with the evil and wickedness that God sought to wipe out through the flood. How then could your wife be descended from a population that was destroyed in the flood?
If the "sons of God" in Genesis 6:4 were angels, then it appears that Jude speaks of them.
Jude 1:6-7 6 You also know that
the angels who did not keep within their proper domain
but abandoned their own place of residence, he has kept
in eternal chains
in utter
darkness, locked up
for the judgment of the great Day.
7 So also
Sodom and Gomorrah and the neighboring towns,
since they indulged in sexual immorality and pursued unnatural desire
in a way similar to
these angels,
are now displayed as an example by suffering the punishment of eternal fire.
Context (NET) Clearly God disapproved of what these angels did and he punished them for their actions. And since he so disapproved of what they did, the Nephilim could hardly have been God's greatest creation. Nor could it have been God's will for the angels to do what they did.
Your wife's beliefs are certainly unscriptural. But telling her that may not help since she does not respect the scriptures as God's word to man. IMO, there are two likely explanations for her aberrant beliefs. One is that she has a mental problem of some kind, in which case, you should seek professional help. The other is that she has indeed been having conversations, but not with God's holy angels. We are told that Satan disguises himself as an angel of light (2 Cor 11:14), and it is possible that your wife has been listening to a lying spirit and has been deceived by it. In that case you are faced with a spiritual battle, and I would encourage you to fast and pray together with others you know that the deception might be broken.
