Mark 1:23-28

Just then a man with an unclean spirit was in their synagogue. He cried out,  “What do you have to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are — the Holy One of God!” Jesus rebuked him saying, “Be silent, and come out of him!” And the unclean spirit threw him into convulsions, shouted with a loud voice, and came out of him. They were all amazed, and so they began to ask each other, “What is this? A new teaching with authority! He commands even the unclean spirits, and they obey him.” At once the news about him spread throughout the entire vicinity of Galilee.
