There is a passage in the Holy Bible (Genesis 6:1-4 - "sons of God") that is argued as being incorrectly interpreted by some Bible believers, as being angels, because in the case of this scripture they are described as having interbred with human women, which brought to the earth an angel-man hybrid species called “the Nephilim”, meaning “fallen ones” (very large beings/giants). This act of an attempt by Holy Angels, influenced by Satan to defile the bloodlines of humans, was immediately followed by God’s warning to Noah, that he would be destroying all flesh on the earth with a worldwide flood in 120 years from that point in time.
Jude 1:6-7 "And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day. Even as Sodom and Gomorrah, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
The above quoted scripture from Jude, has reasoning that needs followed through in the fact that it states these angels left their first estate and were chained under darkness. It follows immediately in the next verse saying Sodom and Gomorrah and cities around them, 'in similar manner to these' ('these' being the angels just spoken of), gave themselves over to sexual immorality and going after strange flesh (a definite comparison intended).
"Sons of God" (Genesis 6:2) is a term also used of angels in scriptures such as some Book of Job, Old Testament verses/passages: Job 1:6, Job 2:2, Job 38:7. We see in Isaiah 14:12 that the former Lucifer is referred to as "son of the morning". Daniel 3:25 Says by the mouth of Babylonian king Nebuchadnezzar, who was executing and witnessing 3 Hebrew/Jewish men in a fiery furnace of capital punishment, that a fourth man appeared in the furnace with Daniel's 3 death-sentenced friends who was "like the Son of God". Later, in Daniel 3:28 "Nebuchadnezzar spake, and said, Blessed be the God of Shadrach, Meshach, and Abednego, who hath sent HIS ANGEL, and delivered his servants..."
The NIV says in Genesis 6:2 that "sons of God saw the daughters of humans" (obvious distinction). The old, paraphrased Living Bible (TLB - paraphrased scripture) gives an even greater distinction in its passage of Genesis 6, calling Angels that interbred with human women (giving rise to the birth of "giants"), as "beings from the spirit world" who took wives from among "earth women".

The three Bible Translation's/versions of Genesis Chapter 6:1-2 that I have referenced - - -
(King James Version) - - -
"And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, that the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
(New international Version) - - -
"When human beings began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose.
(The Living Bible) - - -
Now a population explosion took place upon the earth. It was at this time that beings from the spirit world[a] looked upon the beautiful earth women and took any they desired to be their wives.

I am a graduate of Liberty University (1996) for completion of theological studies (33 college credits), and I completed "Bible Survey" with Assemblies of God - Berean College. I consider myself a "Bapticostal" (a Baptist also having Pentecostal beliefs). Bible studies are one of my most-covered book subjects. I am, however, careful to only address those subjects I believe God has given me correct revelation on. I was a Christian Youth Minister, beginning in 1983 for approximately 18 years. During, between and after youth ministries I served in other church capacities as well, including interim pastoring and retirement home ministry. MOST IMPOTANTLY, I am a redeemed man, who has received salvation by acceptance of Jesus Christ (John 3:16) and what he did for me in shedding his blood and dying for me on the cross, and in his resurrection from the dead, giving me the promise of eternal life, purely by grace; not due to anything I have done, other than to accept it freely.
