Azael is one of the principal evil angels who lived with mortal women. The name Azael means "who God strengthens" not to be mixed up with the angel Azazel, whose name means "God strengthens".
According to lore, Azael slept with Naamah and spawned Assyrian guardian spirits known as sedim, invoked in the exorcism of evil spirits. As punishment, Azael is chained in a desert until Judgement Day. In magical lore, he guards hidden treasure.
