בֵּ֧ית קָדְשֵׁ֣נוּ וְתִפְאַרְתֵּ֗נוּ אֲשֶׁ֤ר הִֽלְל֙וּךָ֙ אֲבֹתֵ֔ינוּ הָיָ֖ה לִשְׂרֵ֣פַת אֵ֑שׁ וְכָל־מַחֲמַדֵּ֖ינוּ הָיָ֥ה לְחָרְבָּֽה׃
Tus santas ciudades están desiertas, Sión es un desierto, Jerusalem una soledad.
Nefesh HaChayim
Similarly, any sin or transgression of a Jew when he permits the entrance of anger or evil thoughts/lusts into his heart ח''ו it is as if he brought an alien fire upon the altar. Meaning to say: A man in actuality through his thoughts and deeds brings a devouring fire to His house, which was our glory and splendor, May the Merciful One save us, May he be Blessed.
