'Demon' in the Bible

And in the synagogue there was a man, that had a spirit of an unclean demon; and he cried out with a loud voice,

And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the demon had thrown him down in the midst, he came out of him, having done him no hurt.

For John the Baptist is come eating no bread nor drinking wine; and ye say, He hath a demon.

For he was commanding the unclean spirit to come out from the man. For oftentimes it had seized him: and he was kept under guard, and bound with chains and fetters; and breaking the bands asunder, he was driven of the demon into the deserts.

And as he was yet a coming, the demon dashed him down, and tare him grievously. But Jesus rebuked the unclean spirit, and healed the boy, and gave him back to his father.

And he was casting out a demon that was dumb. And it came to pass, when the demon was gone out, the dumb man spake; and the multitudes marvelled.
