(a-bad'don),or Apollyon,(Heb. destruction), (Gr. in Rev. ix: 1 1, where it is rendered by the Greek, ap-ol-loo' ohn, destroyer).

The former is the Hebrew name, and the latter the Greek name, ascribed (Rev. ix:n) to the angel of the abyss, or Tartarus, i. e., the angel of death. He is represented as the king and head of the Apocalyptic locusts under the fifth trumpet (Rev. ix:ii). In the Bible, the word Abaddon means destruction (Job xxxi:i2) or the place of destruction, i. e., the subterranean world, Hades, the region of the dead (Job xxvi:6; xxviii:22; Prov. xv:ll). There is a general connection with the destroyer — referred to in I Chron. xxi 115. It is in fact the second of the seven names which the Rabbins apply to that region; and they deduce it particularly from Ps. lxxxviii:n. 'Shall thy loving kindness be declared in the grave, or thy faithfulness in (abaddon) destruction?' (See HADES; LOCUST.)
