עובדיה, פרק א׳, פסוק ו׳

The fall of Edom is marked by a complete and unprecedented plundering, leaving absolutely nothing behind. The sheer thoroughness of this looting sparks deep astonishment, as even the nation's most heavily guarded and deeply hidden treasures are laid bare. Repeated emphasis is used to highlight the absolute ruin of the nation [רד״ק, מצודת דוד]. The homes of Esau face a thorough search, with every secret hiding spot and heavily protected vault targeted by the invaders [מצודת ציון, שטיינזלץ, צאינה וראינה].

The primary approach among commentators is that the enemies conduct a careful, demanding hunt for loot. At the same time, this process involves the physical exposure and unearthing of everything that was once kept safely out of sight [רש״י, מלבי״ם].

The shock of this event raises questions about how such a complete robbery could even take place. One perspective highlights the deep humiliation of the nation. Normal thieves operate in a rush, driven by the fear of being caught. In this case, however, the invaders act with complete ease. They take their time searching every hidden corner, entirely unafraid that the Edomites might stand up and defend their property [מלבי״ם]. Another perspective focuses on how the invading forces could possibly know the exact locations of Esau's deepest secrets and hidden wealth. The answer lies in betrayal. Esau’s closest allies and trusted confidants, who are intimately familiar with these secret locations, are the very ones who surrender the nation and its treasures directly to the enemy [אברבנאל].
