Nephilim are a hybrid between a human female and a fallen angel.
Nephilim – Hebrew – “The Fallen Ones” Greek - Septuagint – gigantes = giants
Gigas = “Earth Born”
Picture of Fallen Angel with a Human Female
King James Version
Gen. 6:4 There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.
America Standard Version
Gen. 6:4 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.
Why did Satan have fallen angels co-habit with human females?
It was Satan’s plan to defile the pure Adamite bloodline with these Nephilim. The why of this is plain as it can be. Jesus was a pure descendant of Adam via Noah and others. Look at the first chapter of Matthew to see a listing of all the lineage of Jesus. When Noah and the other seven were on the ark, God was just wiping the slate clean. But, the 400 years between then and Moses gave Satan time to re-defile the land with Nephilim.
Gen. 6:9 ¶ This is the genealogy of Noah. Noah was a just man, perfect in his generations. Noah walked with God.
Perfect - Tamiym = “without blemish, sound, healthful, without spot, unimpairted”
In Numbers 13 Moses sends in the 12 spies to check out the Promised Land.
Num. 13:33 And there we saw the Nephilim, the sons of Anak (the sons of Anak are part of the Nephilim), who come of the Nephilim: and we were in our own sight as grasshoppers, and so we were in their sight.
It has also been suggested that daemons are the Nephilim spirits that are left after one of them are killed.
It has also been suggested that modern day Nephilim are the aliens that people seem to encounter. Being ½ angel, they have knowledge and access to the 2nd Heaven that the Bible says Satan now has control over. The Bible refers to Satan has the God of the Air, or 2nd Heaven. They are not from outer space, but are doing some sort of Hyper-dimensional travel back and forth from the 2nd Heaven.
This would make sense to many of the sightings where the craft they are in are reported to “just disappear” in the blink of an eye.
Luke 17:26 And as it was in the days of Noah, so shall it be also in the days of the Son of man.
There were Nephilim in the Days of Noah, could it not mean also that the Nephilim are not going to return in the last days?
I know that what I have read in the Bible where it talks about daemons, and the description of aliens given by those who have seen them; sure do sound very similar to me. This just may the answer that many have been looking for.
