EXORCIST

one who pretends to expel evil spirits by conjuration, prayers and ceremonies. Exorcism was frequently practiced among the Jews. (Matthew 12:27; Acts 19:13) David, by playing skillfully on a harp, procured the temporary departure of the evil spirit which troubled Saul. (1 Samuel 16:23) The power of casting out devils was bestowed by Christ while on earth upon the apostles, (Matthew 10:8) and the seventy disciples (Luke 10:17-19) and was, according to his promise, (Mark 16:17) exercised by believers after his ascension. (Acts 16:18)
