The most common English synonym for 'Satan' is 'Devil', which descends from Middle English devel, from Old English dēofol, that in turn represents an early Germanic borrowing of Latin diabolus (also the source of 'diabolical').Abrahamic religious belief systems other than Judaism relate this term to a demon, a rebellious fallen angel, devil, minor god and idol, or as an allegory for knowledge or the enlightenment of mankind.
Micha'el or Mîkhā'ēl; Greek: Μιχαήλ, Mikhaíl; Latin: Michael or Míchaël; Arabic: ميخائيل, Mikhā'īl) is an archangel, one of the principal 50 angels in Christian and Islamic tradition. He is viewed as the field commander of the Army of God.
