Mark 1:21-28

They went into Capernaum, and right away he entered the synagogue on the Sabbath and began to teach. They were astonished at his teaching because he was teaching them as one who had authority, and not like the scribes. 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.
