Fallen Angels and Satan

In the Jewish tradition, Satan isn’t a “fallen” angel; he’s an angel whose occupation is tempting men to sin, as illustrated in Ch.1 of Job. “Satan” means something like “adversary”; it’s used in that generic sense in Num.22:22. Satan’s proper name is Samael. He guided the serpent in the Garden of Eden to tempt Eve. The angels who fell in Enoch’s time were tempted by human women, as told in Gen.6:1-4. Their leaders were Uza (or Shemchazai) and Azael; the names Uza and Azael may be related to the Azazel of Lev.Ch.16. The Midrash (end of Devarim Rabbah) says that Uza and Azael were punished by being suspended between heaven and earth.
