'Demon' in the Bible

In the synagogue was a man who had a demon. He screamed with a loud voice,

But Jesus rebuked him. "Be quiet," he said, "and come out of him!" At this, the demon threw the man down in the middle of the synagogue and came out of him without hurting him.

Because John the Baptist has come neither eating bread nor drinking wine, yet you say, "He has a demon!'

because Jesus was in the process of ordering the unclean spirit to come out of the man. On many occasions the unclean spirit had seized the man, and though he was kept under guard and bound with chains and shackles, he would break the chains and be driven by the demon into deserted places.

Even while the boy was coming, the demon knocked him to the ground and threw him into convulsions. But Jesus rebuked the unclean spirit, healed the boy, and gave him back to his father.

Jesus was driving a demon out of a man who was unable to talk. When the demon had gone out, the man began to speak, and the crowds were amazed.
