This describes Jerusalem as a woman who sinned, while it also stands for the inhabitants of Jerusalem. AT: "The people of Jerusalem sinned greatly" (See: [[rc://en/ta/man/translate/figs-personification]] and [[rc://en/ta/man/translate/figs-metonymy]])
"her naked." Jerusalem is described as a woman whose private parts have been exposed to everyone to shame her. (See: [[rc://en/ta/man/translate/figs-personification]])
