The Fallen Watchers ~ Grigori
There is a group 
called the Watchers or Grigori. This is the group that this 
passage speaks of. They are said to look like human male, but taller/larger, 
they never slip and they are silent. In Jewish legend/lore it is said that 
there are good and evil watchers, the good watchers residing in the 5th 
Heaven, while the evil ones reside in the 3rd Heaven.
The mysterious eighth order of angels, the gentle Grigori were 
created by God to be Earthly shepherds of the first humans. The Grigori were 
both physically and spiritually gigantic, at least by the standards of the 
people who later wrote about them. They served early humanity as vast 
reservoirs of information concerning the finer points of civilization, and 
their selflessness was beyond compare. They were also called the Watchers, 
as it was their job to observe humanity, lending a helping hand when 
necessary but not interfering in the course of human development.
In the Book Of 
Enoch, it describes that God had sent a legion of angels to earth in order 
to watch over and assist man during the beginning of civilization. These 
angels taught man sciences which were forbidden by God such as the magic in 
herbs, reading the stars, divination and sorcery. 
Enoch goes on to 
say:..but they chose husbands and wives from among the humans and led greatly 
debauched lives, neglecting their heavenly duties...This angered God 
greatly and he banished the fallen & Sadly these 
angels were not suited to this job and instead of playing a positive role 
they began to teach man sciences that God had deemed to be forbidden.
These subjects included astrology, divination, herb craft and magic. 
To compound this, they also began to lust after some of the women they were 
supposed to be guiding. In order to cohabitate with these women they even 
assumed physical forms. Although the church might argue that angels have no 
gender and therefore are unable to procreate anyway, the following excerpt 
from Genesis 6:4, points out that "the sons of God went to the daughters of 
men and had children by them . The resulting half-breeds were named as the
Nephilim This kind of bad 
angelic behavior could not be tolerated and as a result the Grigori were 
taken from their posts and imprisoned in a layer of heaven. Although they 
appealed to Enoch to speak on their behalf to God, they remained bound for 
70 generations. As for the Nephilim, it has been suggested that one of the 
main reasons for the great flood, was not only to punish man, but to cleanse 
the earth of the half-bred creatures created from the union of fallen spirit 
and flesh. Among the Strega 
the Watchers are called the Grigori. Originally there were 4 royal stars or 
Lords and they were called the Watchers. Each of these Lords ruled over one 
of the 4 cardinal points...North, South, East, West.
North - Formalhaut - who marked Winter Solstice
South - Regulus - who marked Summer Solstice
East - who marked the Vernal Equinox
West - who marked Autumn Equinox
In the Strega 
Mythos, the Watchers were Gods who guarded the Heavens and Earth. Over time 
the Greeks made them Gods of the 4 winds, and the Christians made them 
creatures of the Air. In Stregheria we call the elements from the altar. The 
Grigori are of a higher realm and guard the portals to the gods.
In A Dictionary of Angels by Gustav Davidson, the good Watchers are 
portrayed as a high order of Angels, (Archangels), also known as Grigori or
Irin
Chief of the 
Good Grigori are Archangels: 
Uriel, Raphael, Raguel, Michael, Zerachiel, Gabriel, and Remiel
