AZAZIL (عزازل).  Arabic name meaning "removed, separated."  It is the same as Hebrew Azazel (עֲזָאזֵל). 

AZAZIL.  In Milton's Paradise Lost, Azazil is the standard-bearer of the infernal host.  According to the Koran, when God commanded the angels to worship Adam, Azazil replied, "Why should the son of fire fall down before a son of clay?" and God cast him out of heaven.  His name was then changed to Eblis, which means "despair."
    "Then straight commands that at the warlike sound / Of trumpets loud, and clarions, be upreared / His mighty standard; that proud honour claimed / Azazil, as his right, a cherub tall."—Milton: Paradise Lost, book i. 531-4. (Dictionary of Phrase and Fable, Brewer, 1905)

    The Etymology which Kimky, Pomarius and Aquinas have given this word, is uncertain, and contrary to the Rules of Grammar; making it a compound of Aaz, a Goat, and Azel, put back; because the one is of the Feminine Gender, and the other of the Masculine.  But 'tis certain that the Verb Azal signifies to put back or to remove, and that 'tis usual with the Hebrews to double the first Syllable of their Nouns to denote the Superlative.  The learned Bochart is of opinion, that the word Hazazel, is the same with the Arabick word Azazil, which signifies separated or removed; And others in fine think that the Goat was so called, from a Mountain of that name near Sinai, whither it was to be sent...
