Continuation of Chapter 3 - Who were the Nephilim ?

According to Hebrew writings and other apocryphal books (such as the book of Enoch), the Nephilim were a race of giants and super - heroes, who committed acts of great evil. Their great size and power seemed to come from the mixture of their demonic DNA and human genetics. All the Bible says directly about them is that they were “mighty men which were of old, men of renown". (Genesis 6 verse 4) The Nephilim were not aliens, as many people often think, they were literally physical beings produced by the union of the “sons of God” (fallen angels) and daughters of men. 

The Nephilim were one of the main reasons for the great flood in Noah's time . Immediately after the Nephilim are mentioned, the word of God tells us that, " When the Lord saw how wicked everyone on earth was and how evil their thoughts were all the time, he was sorry that he had ever made them and put them on the earth. He was so filled with regret that he said, “I will wipe out these people I have created, and also the animals and the birds, because I am sorry that I made any of them.”(Genesis 6 verses 5-7) So God proceeded to flood the world, killing all and everyone, including the race of giants, saving only Noah and his family, and the animals within the ark (Genesis 6:11-22).

The bible tells us that “Noah had no faults and was the only good man of his time.”…in other words, Noah was not contaminated with the DNA of the Nephilim.

Related to the fact that Angels had relations with human woman, it is interesting to note a text of the book of Job, the oldest book of the bible:

This book is written by the patriarch Job, who lived close to the time of the flood, thus the references to angels reflect this. There is a passage that states directly that certain angels were indeed involved in illicit relations with human women. It occurs when Eliphas, one of Job’s three friends who are trying to encourage him over the loss of his family, shares a Divine vision he had:

 We read in Job 4 verses 13 -18: “Now a thing was secretly brought to me, and mine ear received a little thereof.  In thoughts from the visions of the night, when deep sleep falleth on men, Fear came upon me, and trembling, which made all my bones to shake.  Then a spirit passed before my face; the hair of my flesh stood up:  It stood still, but I could not discern the form thereof: an image was before mine eyes, there was silence, and I heard a voice, saying,  Shall mortal man be more just than God? Shall a man be more pure than his maker?  Behold, he put no trust in his servants; and his angels he charged with folly”.

The word “folly” in the Old Testament is used to describe sexual sin.

We can see that also in other places such as in Genesis 34: 7 (“because he had wrought folly in Israel in lying with Jacob's daughter”) and also in 2 Samuel 13 verse 12 (“And she answered him, Nay, my brother, do not force me; for no such thing ought to be done in Israel: do not thou this folly”).

These and other passages in the bible give us more and more the guarantee that the giants (nephilim) were indeed beings, produced by the union of the “sons of God”, (fallen angels), and daughters of men. They have no relation whatever with the so-called “aliens”, that many people wrongly believe, are visiting us from outer space.
