Mondo shtuff from around the internet, all about ABADDON!
My botty best at summarizing from Wikipedia: in the Hebrew Bible, abaddon is used with reference to a bottomless pit . its Greek equivalent Apollyon appears as both a place of destruction and an angel of the abyss . the the Biblical Antiquities (misattributed to Philo) mentions Abaddon as a place (destruction) rather than an individual . Proverbs 27:20: Hell (Sheol) and Destruction ( in Revelation 9:11, abaddon is described as “Destroyer”, the angel of the abyss . Protestant commentator Matthew Henry (1708) believed Abaddon to be the Antichrist . the angel having “the key of the abyss” is actually shown to be a representative of God . Revelation 20:1-3 concludes that “abaddon” is another name for Jesus after his resurrection . abbaton was promised that any who venerated him in life could be saved . he is also said to have a prominent role in the Last Judgement . described in the Apocalypse of Bart The Oxford Companion to the Bible.
