Yahweh uses this rhetorical question to emphasize that no one should mourn for Jerusalem. This question can be written as a statement. Alternate translation: "No one should have compassion on you, Jerusalem. No one should mourn for your destruction." (See: [[rc://en/ta/man/translate/figs-rquestion]])
Here "Jerusalem" refers to the people who live there. Alternate translation: "for you people who live in Jerusalem" (See: [[rc://en/ta/man/translate/figs-metonymy]])
