EXORCIST
People who sought to cast out evil spirits and ward off their pernicious influence, with the help of certain verbal formulas or magical spells.
Paul found traveling Jews in Ephesus who claimed to exorcise the possessed, but they were nothing more than impostors (Acts 19:13-19).
The case of the Lord Jesus and his disciples is very different, who cast out evil spirits by divine authority, and without resorting at all to the procedures of exorcism.
