Mark 1:21-24

They went into Capernaum, and immediately on the Sabbath Jesus went into the synagogue and began to teach. [Luke 4:31-37] They were completely amazed at His teaching; because He was teaching them as one having [God-given] authority, and not as the scribes. Just then there was a man in their synagogue with an unclean spirit; and he cried out [terribly from the depths of his throat], saying, “What business do You have with us, Jesus of Nazareth? Have You come to destroy us? I know who You are—the Holy One of God!”
