'Demon' in the Bible

Now the woman was a Gentile (Greek), a Syrophoenician by nationality. And she kept pleading with Him to drive the demon out of her daughter.

And He said to her, “Because of this answer [reflecting your humility and faith], go [knowing that your request is granted]; the demon has left your daughter [permanently].”

And returning to her home, she found the child lying on the couch [relaxed and resting], the demon having gone.
