Apocryphal Books and Nephilim
The subject of the Sons of God and the Nephilim is also discussed in unscriptural apocryphal writings, particularly the books of Enoch, Jubilees, and Jasher. They are not helpful, but they are of interest to scholars because they tell us the beliefs that were current at the time they wrote. Here is a short list of works that talk about the Nephilim and their fathers who are the Sons of God.
The book of Enoch is most often cited as having useful information about the Sons of God and their off-spring. In Enoch the giant offspring, the Nephilim, are 3000 ells tall which is 300 cubits or about 450 feet tall. Any person of that height would not have the muscular ability to lift his own bones to a sitting position, much less stand or walk. Enoch also wrote that the Sons of God are angels (refuted by Hebrews 1:5).
Another work, the book of Jubilees contributes almost nothing which is not in the biblical record:
“,,, the angels of God saw them on a certain year of this jubilee, that they were beautiful to look upon; and they took themselves wives of all whom they chose, and they bare unto them sons and they were giants.”
• Jubilees 5:1
The Jewish historian Josephus also discusses the giants, the Nephilim, telling the beliefs among the Jews of the 1st century:
“for many angels of God accompanied with women, and begat sons that proved unjust, and despisers of all that was good, on account of the confidence they had in their own strength; for the tradition is, that these men did what resembled the acts of those whom the Greeks call giants.”
• Josephus, Antiquities of the Jews 1:73
The Book of Jasher is often cited as a source, but there are several works with this title. The origin of this work has a very uncertain origin. It also says angels mated with the daughters of men. An extremely well educated and sophisticated 1st century Jewish philosopher, Philo of Alexandria, wrote a book titled “On Giants.” He largely allegorizes the entire episode in Genesis 6: –4. Philo also believed angels married the daughters of men.
“On what principle it was that giants were born of angels and women? … But he [supposedly Moses] relates that these giants were sprung from a combined procreation of two natures, namely, from angels and mortal women; for the substance of angels is spiritual: …”
• Questions in Genesis 1:92
Philo also believed Nimrod was a giant (Questions in Genesis 1.92). Elsewhere he identified the giants with an elder group of Greek gods, the Titans:
“… rather like a giant born of the earth, prefers earthly to heavenly things, and thus appears to verify the ancient fable of the giants and Titans;”
• Questions in Genesis 2:82
These and other sources are discussed and analyzed by the 1,250,000+ internet websites and hundreds of books regarding the origin of the Nephilim and their sires, the Sons of God. See “Notes on the Nephilim: The Giants of Old,” compiled by Lambert Dolphin. In this compilation, seven authors attempt to present biblical evidence of the three theories I mentioned above. They give the clearest possible presentations and conclusions from an evangelical Christian perspective — and each one is biblically erroneous.
