לַ֤יְלָה וְיוֹמָם֙ לֹ֣א תִכְבֶּ֔ה לְעוֹלָ֖ם יַעֲלֶ֣ה עֲשָׁנָ֑הּ מִדּ֤וֹר לָדוֹר֙ תֶּחֱרָ֔ב לְנֵ֣צַח נְצָחִ֔ים אֵ֥ין עֹבֵ֖ר בָּֽהּ׃
It shall not be quenched night nor day, The smoke thereof shall go up for ever; From generation to generation it shall lie waste: None shall pass through it for ever and ever.
Read kabbalistic (mystical) interpretation of Isaiah 34:10: and classical mystical sources.
