The grand appearance of a capital city often hides a harsh moral reality, where rapid development and construction are achieved at the expense of the weak. The prophet strips away this glorious exterior to expose the corrupt foundations supporting the nation's leadership. The primary approach among commentators is that the blame falls directly on the leaders, military officers, and the wealthy elite. These individuals construct their private homes and fund city projects through ruthless exploitation and extortion [אבן עזרא, רד״ק, מצודת דוד, ביאור שטיינזלץ]. Another perspective frames the prophet's message as a sharp rhetorical question directed at these corrupt officials. It challenges the absurd idea that God, the true builder of the city, would ever construct His home using violence and crime. This view mocks the dangerous illusion held by the leaders, who believe they can pervert justice, accept bribes, and oppress the poor, while still relying on God and trusting that His presence will shield them from disaster [מלבי״ם, אברבנאל].
The violence fueling this urban expansion takes several forms. In a metaphorical sense, the shedding of blood represents extreme economic oppression, robbery, and violence against the poor. Stripping a destitute person of the very resources they need to survive is equated to actual murder [רד״ק, אבן עזרא]. On a more literal level, the building is funded by actual murder committed to seize the victims' property [מצודת דוד, ביאור שטיינזלץ]. It also involves the practice of accepting bribes and ransom money from murderers and using those funds for construction projects [רד״ק], or even engaging in other grave sins such as idolatry [אברבנאל]. Beyond bloodshed, the city is built on a foundation of everyday injustice, relying on fraud, dishonest business practices, extorted money, and a corrupted legal system [מצודת דוד, ביאור שטיינזלץ].
A distinct line is drawn between different parts of the capital. Zion represents the seat of government and the core of royal power, and it is built upon the most severe crimes of murder and violence. Jerusalem, on the other hand, represents the wider city where the general public lives. In these ordinary neighborhoods, the daily routine is defined by a constant stream of deceit, fraud, and general dishonesty [מלבי״ם].
