Chorazin is mentioned explicitly only in Matthew 11:21 and Luke 10:13. In both passages Jesus pairs it with Bethsaida and declares that if the mighty works performed in these Galilean towns had occurred in Tyre and Sidon, those pagan cities would have repented.
The statement indicates that Jesus conducted more ministry in Chorazin than the surviving Gospel narratives individually describe. The town therefore provides an important reminder that the Gospels record selected events rather than every act of Jesus' ministry.
Chorazin also illustrates the biblical theme that receiving greater revelation brings greater responsibility. Its inhabitants had witnessed extraordinary evidence yet failed to respond appropriately.
