Angels-NEPHILIM

The biblical term Nephilim, which in Hebrew means “the fallen ones”
or “those who fell,”

refers to the offspring of the sons of God (traditionally
interpreted as angels) and mortal women mentioned in Gen.
6:1–4. A fuller account is preserved in the apocryphal Book of Enoch,
which recounts how a group of angels left heaven to mate with
women and taught humanity such heinous skills as the art of war. The
chief distinguishing characteristic of the Nephilim was their gigantic
size. These giants are mentioned a number of times in both the Scriptures
and the noncanonical books. There is a particularly vivid image
in the book of Numbers, at a point where the wandering Israelites
come upon a land occupied by giants. The Hebrew scouts give the following
report:
[A]ll the people that we saw in it are men of great stature.
And there we saw the Nephilim (the sons of Anak, who come
from the Nephilim); and we seemed to ourselves like
grasshoppers, and so we seemed to them. (Num. 13:33)
Other groups of exceptionally tall people who appear to have
been descendants of the Nephilim, such as the Anakim and the
Rephaim, are mentioned in the books of Deuteronomy (2:11; 2:20;
3:11; 3:13) and Joshua (12:4; 13:12; 15:8; 17:15; 18:16).
There were still descendants of the Nephilim during King David’s
time. Four enormous members of the Philistine army are mentioned in
2 Samuel and in parallel verses in 1 Chronicles. These passages
observe that at least one of these four men had six fingers on each
hand and six toes on each foot, traits that may have marked the entire
race. The author of 2 Samuel also notes that “these four were descended
from the giants in Gath” (21:22)—which was the homeland of
Goliath, the most famous giant in the Bible.
There are other allusions to the descendants of the Nephilim in
the apocryphal books of Judith (16:6), Sirach (16:7), Baruch
(3:26–28), and the Wisdom of Solomon (14:6).
