Mythology Links - Abaddon
"The Hebrew term Abaddon (Hebrew: אֲבַדּוֹן, 'Ǎḇaddōn), an intensive form of the word "destruction", appears as a place of destruction in the Hebrew Bible.
In a vision in the New Testament Book of Revelation, an angel called Abaddon is shown as the king of an army of locusts; his name is first transcribed in Greek as "whose name in Hebrew Abaddon" (Ἀβαδδὼν), and then translated as, "which in Greek means the Destroyer" (Apollyon, Ἀπολλύων). The Latin Vulgate, as well as the Douay Rheims Bible, has an additional note (not present in the Green text), "in Latin Exterminans", exterminans being the Latin word for "destroyer"."
