Greek word ἐγρήγοροι egrḗgoroi, meaning "wakeful". The Hebrew equivalent is ערים, meaning "waking", "awake". Chapter 18 presents the Grigori as countless soldiers of human appearance, "their size being greater than that of great giants". They are located in the fifth heaven and identified as "the Grigori, who with their prince Satanail rejected the Lord of light". One version of 2 Enoch adds that their number was 200 myriads (2 million). Furthermore, some "went down on to earth from the Lord's throne" and there married women and "befouled the earth with their deeds", resulting in confinement underground. The number of those who descended to earth is generally put at three, but Andrei A. Orlov, while quoting the text as saying three, remarks in a footnote that some manuscripts put them at 200 or even 200 myriads. Chapter 29, referring to the second day of creation, before the creation of human beings, says that "one from out the order of angels" or, according to other versions of 2 Enoch, "one of the order of archangels" or "one of the ranks of the archangels" "conceived an impossible thought, to place his throne higher than the clouds above the earth, that he might become equal in rank to [the Lord's] power. And [the Lord] threw him out from the height with his angels, and he was flying in the air continuously above the bottomless." Although in this chapter the name "Satanail" is mentioned only in a heading added in one manuscript, this chapter too is often understood to refer to Satanail and his angels, the Grigori. The Mercer Dictionary of the Bible makes a distinction between the Grigori and the fallen angels by stating that in fifth heaven, Enoch sees "the giants whose brothers were the fallen angels." The longer recension of 2 Enoch 18:3 identifies the prisoners of second heaven as the angels of Satanail. Book of Giants The story of the Watchers is shown also in the Book of Giants. Philo According to PrEv 1.10.1-2 of Philo of Byblos, Sanchuniathon mentioned "some living beings who had no perception, out of whom intelligent beings came into existence, and they were called Zophasemin (Heb. șōpē-šāmayim, that is, 'Watchers of Heaven'). And they were formed like the shape of an egg." Jubilees The term "Watchers" occurs in the Book of Jubilees (Jub. 4:15, 5:1). Damascus Document A reference to the "fall of the watchers from
