What does Luke 10:13 mean?

'Shame on you, Chorazin! Shame on you, Bethsaida! If the miracles done in you had happened in Tyre and Sidon, those cities would have turned their lives around long ago, sitting in ashes and wearing sackcloth.' Luke 10:13 - Modern Text Bible

(Jesus rebukes towns that witnessed his miracles but didn’t change, saying even notorious pagan cities would have repented if they’d seen such things.)
