'Unclean Spirit' in the Bible

And amazement came upon all, and they spoke one to another, saying: "What teaching is this? for with authority and power he commands the unclean spirits, and they come out.

For he had O; commanded the unclean spirit to come out of the man. For it had often seized upon him, and he had been bound with chains and fetters, and kept in confinement; and he broke the bonds, and was driven by the demon into the deserts.

And while he was coming, the demon cast him to the ground, and threw him into convulsions; but Jesus rebuked the unclean spirit, and restored the child to health, and gave him back to his father.

"When the unclean spirit has gone out of a man, he goes through dry places, seeking rest; and finding none, he says, I will return to my house out of which I came.
