'Demon' in the Bible

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

But Jesus rebuked him: "Silence! Come out of him!" Then, after the demon threw the man down in their midst, he came out of him without hurting him.

For John the Baptist has come eating no bread and drinking no wine, and you say, 'He has a demon!'

For Jesus had started commanding the evil spirit to come out of the man. (For it had seized him many times, so he would be bound with chains and shackles and kept under guard. But he would break the restraints and be driven by the demon into deserted places.)

As the boy was approaching, the demon threw him to the ground and shook him with convulsions. But Jesus rebuked the unclean spirit, healed the boy, and gave him back to his father.

Now he was casting out a demon that was mute. When the demon had gone out, the man who had been mute began to speak, and the crowds were amazed.
