The downfall of a once-proud city is marked not just by physical destruction, but by profound public humiliation. The punishment continues a harsh metaphor that compares the city to a disgraced, immoral woman. The physical imagery of dirt and ugliness serves as a symbol for the complete shattering of the society. As the enemy invades, they will spread total ruin, strip away the city's former beauty, and drag its people into captivity. This defeat will be steeped in such deep shame that the city will become entirely despised by the rest of the world [רד״ק, מצודת דוד, מלבי״ם].
God will actively cast foul and repulsive things upon the city. Commentators differ on the exact nature of this filth. One approach suggests that He will hurl harsh words and public condemnations designed to tear down the city's glamorous image [רד״ק]. Conversely, another view ties this action directly back to the metaphor of the disgraced woman, explaining that God will cover her in soiled, dirty garments to ensure she appears utterly repulsive [רש״י].
The process of bringing disgrace upon the city involves intense pollution and the casting of permanent flaws. This concept of defilement is so severe that it is linked to the decay and impurity of a dead carcass, emphasizing a total loss of life and beauty [מלבי״ם, מצודת ציון, ביאור שטיינזלץ].
The climax of this punishment is the ultimate public degradation. The city will be reduced to the status of absolute filth and raw waste. The primary approach among commentators notes that the concept here mirrors the waste parts removed from a bird offering described in the Book of Leviticus, representing pure refuse. Ultimately, God will transform the city into something so deeply polluted and ugly that it will physically repel anyone who looks at it [רד״ק].
