שִֽׁמְמ֤וֹת עוֹלָם֙ אֶתֶּנְךָ֔ וְעָרֶ֖יךָ לֹ֣א תישבנה [תָשֹׁ֑בְנָה] וִֽידַעְתֶּ֖ם כִּֽי־אֲנִ֥י יְהוָֽה׃
Я сделаю тебя вечным опустошением, и твои города не вернутся; и узнаете, что Я Господь.
Rashi
The enemy has been destroyed for the swords of hatred are perpetually upon him like a sharp sword. Another explanation: חרבות לנצח that enemy, the swords of whose hatred were upon us forever. That is the one concerning whom it is stated (in Amos 1:11): “and kept their fury forever.” Another explanation: חרבות is an expression of destruction, and this is its interpretation: The enemy has been destroyed; his ruins are perpetual. And so it is stated (in Ezek. 35:9): “I will make you perpetual desolations, and your cities shall not be restored.”
