The dwelling place chosen by a wicked and arrogant person often serves as a mirror, reflecting his power, his deep fears, or his bitter end. The primary approach among commentators is that this choice of residence highlights pure arrogance in the present world. Driven by pride and an intense desire to leave a lasting legacy, a wicked individual will pour his vast wealth into rebuilding ancient, desolate ruins. These are places so thoroughly destroyed over time that their walls have completely crumbled into mounds of stones, and no ordinary person would ever consider settling them.
Alternatively, this choice of dwelling stems not from pride, but from extreme fear and greed [מלבי״ם]. Overwhelmed by the constant dread that his wealth will be stolen, the wicked person flees to these ruined, isolated places. He hides in caves and dilapidated structures entirely unfit for human living, hoping to remain undiscovered. His deep stinginess further prevents him from spending money to build a proper, permanent home.
Regardless of his motivation, his efforts are ultimately doomed to fail. The cities he attempts to revive are destined to fall into ruin once more. When inevitable disaster strikes, these houses will be left completely empty, turning back into lifeless piles of rubble [רמב״ן].
On a deeper, spiritual level, these dwellings do not refer to physical structures of stone, but rather to a person's final destination after death. The ancient ruins symbolize the graveyard. This serves as a stark warning to those who take pride in their material wealth, reminding them that their ultimate home is the grave. Furthermore, these are places where no one truly lives, because the souls of the wicked do not find rest there. Instead, they are condemned to hell while their physical bodies decay. The only things left standing are the mounds of dirt and tombstones, serving as silent witnesses to their ultimate ruin and loss [אלשיך].
