Capernaum is a town on the northern shore of the Sea of Galilee, with a port for its fishing industry. Jesus went there from Nazareth and found his first disciples, Peter, Andrew, James and John.
Jesus left Nazareth and made his home in Capernaum, in Peter's house, after he heard that John the Baptist had been arrested. It was there Jesus healed the Centurion's servant, Peter's mother-in-law, the paralyzed man who was lowered through the roof, a man who was possessed, and many others who gathered to see Jesus.
It was in Capernaum that Jesus directed Peter to catch a fish with a coin in its mouth to pay the Temple tax. On leaving Capernaum, Jesus condemned it along with other cities that had not heeded his call to repentance.
