Mark 1:22-27

The people were amazed at his teaching, because he taught them as one who had authority, not as the teachers of the law. Just then a man in their synagogue who was possessed by an evil spirit cried out, 'What do you want with us, Jesus of Nazareth? Have you come to destroy us? I know who you are--the Holy One of God!' 'Be quiet!' said Jesus sternly. 'Come out of him!' The evil spirit shook the man violently and came out of him with a shriek. The people were all so amazed that they asked each other, 'What is this? A new teaching--and with authority! He even gives orders to evil spirits and they obey him.' Mark 1:22-27 NIV
