The question this raises is:
If Noah, his sons or any of their wives
had been Nephilim, the text would have certainly mentioned it, and
the Nephilim would have been treated more positively.
It seems that Nephilim were
generated from human stock, not just once but often and separately,
and not only before the flood but also after. The Bible basically
states that biology allows that human females may be and have indeed
been impregnated by spirit beings, a fact of course made ultimately
evident in the conception of Jesus Christ.
The word for children that is used in Numbers 13:28 is (yalad) and means 'born ones,' that means of regular birth and not of some 'son of Elohim.'
The name of the father of Anak is Arba, and his city, Hebron, is given to Caleb (Joshua 15:13). Caleb subsequently drives out the three sons (perhaps again three subdivisions of the Anakim) of Anak, whose names are,
Deuteronomy 2:10 speaks of Emim, a people as great, numerous and tall as the Anakim.
Deuteronomy counts both the Anakim (who are Nephilim) and the Emim among the so-called Rephaim, but in Genesis 14:5 the Rephaim and the Emim are listed separate.
Genesis 14:5 also lists the Zuzim, which
are likely the same as the Zamzuzim of Deuteronomy 2:20, who are a
people like the Anakim and also counted among Rephaim.
First of all, the word nephilim is a plural and the single form, (npl), does not occur in the Bible (which by itself is not at all unusual). In another context, however, the word (nepel) means untimely birth or abortion.
It comes from the verb
(napal), fall, lie down, be cast down, fail. The plural word
means 'fallen ones,' mostly by the sword, and occurs in Joshua 8:25,
Judges 20:46, 2 Kings 25:11, Psalm 145:14, Jeremiah 39:9, 52:15,
Ezekiel 32:22 and 24.
This latter verb is one of many for
prayer and other interventions, and in search of origins of this
particular verb some scholars end up right back at
(napal), to fall (i.e. to prostrate oneself). This becomes
especially compelling when we remember that the name Rephaim has to
do with a verb that means to sink, let drop, fall slack.
