'Evil Spirit' in the Bible

so that even handkerchiefs or aprons were brought from his body to the sick, and the diseases lest them, and evil spirits went out of them.

Then some of the vagabond Jews, exorcists, took upon them to name the name of the Lord Jesus over those that had evil spirits, saying, "We adjure you by Jesus, whom Paul preacheth."

But the evil spirit answered and said, Jesus I know, and Paul I know, but who are ye?

And the man in whom the evil spirit was, leapt upon them, and mastered them, and prevailed against them, so that they fled out of that house naked and wounded.
