Mark 1:22-24

And they were astonished at his doctrine: for he taught them as one that had authority, and not as the scribes. And there was in their synagogue a man with an unclean spirit; and he cried out, saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art, the Holy One of God.
