'Demon' in the Bible

But in the synagogue there was a man possessed by the spirit of a foul demon. In a loud voice he cried out,

But Jesus rebuked the demon. "Silence!" He exclaimed; "come out of him." Upon this, the demon hurled the man into the midst of them, and came out of him without doing him any harm.

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

For already He had been commanding the foul spirit to come out of the man. For many a time it had seized and held him, and they had repeatedly put him in chains and fetters and kept guard over him, but he used to break the chains to pieces, and, impelled by the demon, to escape into the Desert.

On once occasion He was expelling a dumb demon; and when the demon was gone out the dumb man could speak, and the people were astonished.
