'Evil Spirit' in the Bible

In that hour he cured many of diseases and plagues and evil spirits; and to many who were blind he gave sight.

and certain women who had been healed of evil spirits and infirmities: Mary who was called Magdalene, from whom seven demons had gone out;

so that even handkerchiefs or aprons were carried away from his body to the sick, and the evil spirits went out.

But some of the itinerant Jews, exorcists, took on themselves to invoke over those who had the evil spirits the name of the Lord Jesus, saying, "I adjure you by Jesus whom Paul preaches."

The evil spirit answered, "Jesus I know, and Paul I know, but who are you?"

The man in whom the evil spirit was leaped on them, and overpowered them all, and prevailed against them, so that they fled out of that house naked and wounded.
