'Evil Spirits' in the Bible

In that hour he cured many of diseases and plagues and evil spirits; and on many that were blind he bestowed sight.

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

insomuch that unto the sick were carried away from his body handkerchiefs or aprons, and the evil spirits went out.

But certain also of the strolling Jews, exorcists, took upon them to name over them that had the evil spirits the name of the Lord Jesus, saying, I adjure you by Jesus whom Paul preacheth.
