'Demon' in the Bible

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

And Jesus rebuked him, saying, "Be silent and come out of him!" And [after] throwing him down in their midst, the demon came out of him without hurting him at all.

For John the Baptist has come not eating bread or drinking wine, and you say, 'He has a demon!'

For he had commanded the unclean spirit to come out of the man. (For it had seized him many times, and he was bound with chains and shackles [and] was guarded, and breaking the bonds he would be driven by the demon into the deserted places.)

And [while] he was still approaching, the demon threw him down and convulsed [him]. But Jesus rebuked the unclean spirit and healed the boy, and gave him back to his father.

And he was expelling a mute demon. Now it happened that [when] the demon came out, the man who had been mute spoke, and the crowds were astonished.
