יחזקאל, פרק ל״ה, פסוק ט׳

The destiny of Edom is sealed with a decree of absolute and permanent destruction. While other fallen empires might harbor hope for future revival, Edom is condemned to become an eternal wasteland. God promised ultimate restoration for other nations, such as Egypt and Ammon, but the ruin of Edom is uniquely permanent [רש"י]. Its lands are destined to remain in a perpetual state of abandonment and ruin, stretching on forever without end.

The devastation of their cities carries a dual finality. Not only will these urban centers remain entirely empty and devoid of any future inhabitants, but they are also stripped of any chance to ever return to their former glory [רד"ק, מצודת דוד, ביאור שטיינזלץ]. Any human effort to defy this decree will be futile. Even if the people attempt to rebuild from the rubble, God will dismantle their structures, ensuring the cities stay ruined forever [מלבי"ם].

This irreversible punishment serves a greater global purpose. Through the permanent collapse of Edom, God's ultimate justice becomes undeniably clear. The unending desolation stands as a lasting testament to the world, proving God's faithfulness in delivering exact retribution and holding the wicked accountable for their actions [מצודת דוד, מלבי"ם].
