שִׂמְח֧וּ אֶת־יְרוּשָׁלִַ֛ם וְגִ֥ילוּ בָ֖הּ כָּל־אֹהֲבֶ֑יהָ שִׂ֤ישׂוּ אִתָּהּ֙ מָשׂ֔וֹשׂ כָּל־הַמִּֽתְאַבְּלִ֖ים עָלֶֽיהָ׃
你們這些愛耶路撒冷的人，都要與她一同歡喜，為她快樂；你們這些為她悲哀的人，都要與她一同歡欣雀躍。
Taanit
and the sages say, 'Anyone who does work on the Ninth of Av and does not mourn over Jerusalem will not see its rejoicing, as it is stated (Isaiah 66:10), "Rejoice with Jerusalem and be glad with her, all who love her; be gleeful with glee, all who mourn over her."' From here, they said, 'Anyone who mourns over Jerusalem will merit to see her rejoicing; and who does not mourn over Jerusalem will not see her rejoicing.'" It was similarly taught thusly, "Anyone who eats meat and drinks wine on the Ninth of Av, about him the verse states (Ezekiel 32:27), 'and whose iniquities were upon their bones.'"
