The Hebrew term Abaddon (Hebrew: אֲבַדּוֹן Avaddon, meaning “doom”), and its Greek equivalent Apollyon (Greek: Ἀπολλύων, Apollýōn) appear in the Bible as both a place of destruction and an angel of the abyss. In the Hebrew Bible, abaddon is used with reference to a bottomless pit, often appearing alongside the place שְׁאוֹל (Sheol), meaning the realm of the dead.
In the New Testament Book of Revelation, an angel called Abaddon is described as the king of an army of locusts; his name is first transcribed in Greek (Revelation 9:11—”whose name in Hebrew is Abaddon, The Angel of Death.”) as Ἀβαδδὼν, and then translated (“which in Greek means the Destroyer”, Ἀπολλύων, Apollyon). The Latin Vulgate and the Douay Rheims Bible have additional notes (not present in the Greek text), “in Latin Exterminans”, exterminans being the Latin word for “destroyer”. According to the Brown Driver Briggs lexicon, the Hebrew abaddon (Hebrew: אבדון; abaddon) is an intensive form of the Semitic root and verb stem abad (אָבַד) “perish” (transitive “destroy”), which occurs 184 times in the Hebrew Bible. The Septuagint, an early Greek translation of the Hebrew Bible, renders “Abaddon” as “ἀ απώλεια”, while the Greek Apollyon comes from apollymi (ἀ απόλλυμι), “to destroy”. The Greek term Apollyon (Ἀ απολλύων, “the destroyer”), is the active participle of apollymi (ἀπόλλυμι, “to destroy”).
