Asmodeus vs. Abaddon — What's the Difference?

Asmodeus (; Ancient Greek: Ἀσμοδαῖος, Asmodaios) or Ashmedai (; Hebrew: אַשְמְדּאָי, ʾAšmədʾāy), also Asmodevs, Ashema Daeva or Amias (see below for other variations), is a prince of demons, or in Judeo-Islamic lore one king of the earthly spirits called the Ars Goetia, mostly known from the deuterocanonical Book of Tobit, in which he is the primary antagonist. In Peter Binsfeld's classification of demons, Asmodeus represents lust.

The Hebrew term Abaddon (Hebrew: אֲבַדּוֹן ’Ăḇadōn, meaning "destruction", "doom"), and its Greek equivalent Apollyon (Koinē Greek: Ἀπολλύων, Apollúōn meaning "Destroyer") appear in the Bible as both a place of destruction and an archangel of the abyss. In the Hebrew Bible, abaddon is used with reference to a bottomless pit, often appearing alongside the place Sheol (שְׁאוֹל Šəʾōl), meaning the realm of the dead.

A demon appearing in the biblical book of Tobit, considered in the Talmud to be the king of demons and depicted in later Jewish tradition as a mischievous sprite.
