The ruin of a wicked person is absolute and sweeping, leaving nothing but physical and spiritual emptiness in its wake. When a life is built on evil, the very home and family left behind are consumed by desolation, ending in total destruction. As the wicked man falls, something new is scattered across his dwelling, much like grain is tossed across a threshing floor [מצודת ציון, אבן עזרא, ביאור שטיינזלץ].
The primary approach among commentators is that the one left dwelling in this desolate tent is his widow. She continues to live in a home that is no longer his, simply because he has died and vanished [רש״י, מצודת דוד, ביאור שטיינזלץ]. Adding to this complete severance, the home ceases to be his because his widow will eventually marry another man [רמב ן בשם התרגום]. Other traditions view the new occupant of the tent differently. Some suggest that a wild beast will claim the abandoned structure, living where no human remains [אבן עזרא]. Alternatively, the tent itself is stolen, and the wicked man's soul remains trapped there as a captive to the robbers who seized it [רמב״ן]. Another perspective reveals that the home never truly belonged to him in the first place, as it was originally acquired through theft [רלב״ג].
Moving beyond the physical structure, some commentators interpret this dwelling in a deeply personal and spiritual light. Rather than an empty tent, the dwelling represents the human body. In this view, the wicked person's soul remains trapped within his own decaying body in the grave, acutely feeling the pain of its rot [מלבי״ם]. Another spiritual approach identifies the occupant as the evil inclination itself. Acting like a seductive force, this dark urge takes complete control of the person's home, constantly leading him into sin [אלשיך].
The final stage of the wicked person's downfall is marked by a devastating cleansing. Burning sulfur is rained down and scattered over his home, obliterating everything in its path [מצודת דוד, ביאור שטיינזלץ]. This fiery destruction extends into the spiritual realm as well. The sulfur can be seen as the soul burning in the fires of hell after death [מלבי״ם]. Alternatively, it represents the relentless assault of the evil inclination, constantly scattering sins and crimes over the person until he is swiftly and entirely destroyed [אלשיך].
