'Evil Spirit' in the Bible

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

Then some of the wandering Jewish exorcists undertook to name over those who had evil spirits the name of the Lord Jesus, saying, I adjure you by that Jesus whom Paul preacheth.

And the evil spirit answering said, Jesus I knew, and Paul I well know; but who are ye?

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