Jesus teaches with confidence in the synagogue in Capernaum, surprising the congregation with his forthright style unlike the usual religion scholars who quibble and quote. When a man with an unclean spirit interrupts and yells at Jesus, Jesus rebukes the spirit and it leaves the man. The people are amazed at Jesus' new teaching and authority over evil spirits. After leaving the synagogue, Jesus heals Simon's mother-in-law of a fever and that evening heals many sick and afflicted people who come to him, commanding the demons not to speak because they knew his true identity.
