Jesus speaks as if the people of the cities of Chorazin and Bethsaida were there listening to him, but they were not. (See: [[rc://en/ta/man/translate/figs-apostrophe]])
"How terrible it will be for you." Here "you" is singular and refers to the city. If it is more natural to refer to the people instead of a city, you could translate with a plural "you." (See: [[rc://en/ta/man/translate/figs-you]])
The names of these cities are used as metonyms for the people living in these cities. (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/translate-names]])
This can be translated with active forms. AT: "If I had done the mighty deeds among the people of Tyre and Sidon that I have done among you" (See: [[rc://en/ta/man/translate/figs-activepassive]])
Here the "you" is plural and refers to Chorazin and Bethsaida. If it is more natural for your language, you could use a dual "you" to refer to the two cities, or a plural "you" to refer to the people of the cities. (See: [[rc://en/ta/man/translate/figs-you]])
Here "Tyre and Sidon" refers to the people who live there. AT: "God will show more mercy to the people of Tyre and Sidon in the day of judgment than to you" or "God will punish you more severely at the day of judgment than the people of Tyre and Sidon" (See: [[rc://en/ta/man/translate/figs-metonymy]])
The implied information can be made explicit. AT "than for you, because you did not repent and believe in me, even though you saw me do miracles" (See: [[rc://en/ta/man/translate/figs-explicit]])
