Angels-Abaddon

Abaddon (Destroyer) is the Hebrew name for the Greek Apollyon,
known as the Angel of the Bottomless Pit

(Revelation 10), who ties
up the Devil for a millennium (Revelation 20).
Several sources speak of Abaddon, including The Thanksgiving
Hymns (a Dead Sea Scroll), which mentions the “Sheol of Abaddon”
and the “torrents of Belial that burst into Abaddon,” as well as the
first-century Biblical Antiquities of Philo. Abaddon is also referred to as
a place—the pit—in Milton’s Paradise Regained.
Abaddon is further identified as a demon, or the Devil himself, in
the third-century Acts of Thomas, as well as in John Bunyan’s Puritan
classic, Pilgrim’s Progress.
Elsewhere, Abaddon is invoked by Moses to bring down the rain
over Egypt, as reported by Mathers in The Greater Key of Solomon.
There is also a reference to Abaddon as the sixth lodge of the seven
lodges of hell in the work of the Cabalist Joseph ben Abraham
Gikatilla. In various sources, Abaddon is identified as an angel of
death and destruction, demon of the abyss, and chief of demons of the
underworld.
