'Unclean Spirits' in the Bible

Then they were all amazed, so they began to argue with one another, saying, “What is this? A new teaching with authority! He commands even the unclean spirits, and they obey Him.”

Whenever the unclean spirits saw Him, those possessed fell down before Him and cried out, “You are the Son of God!”

And He gave them permission. Then the unclean spirits came out and entered the pigs, and the herd of about 2,000 rushed down the steep bank into the sea and drowned there.

He summoned the Twelve and began to send them out in pairs and gave them authority over unclean spirits.
