The downfall of Babylon is a profound and intensely public humiliation, accompanied by absolute divine vengeance from which there is no escape. Babylon is stripped of her dignity; her garments are torn away, leaving her completely exposed and revealing what ought to remain covered [מצודת ציון, מלבי״ם]. This exposure is a source of deep shame and disgrace. It will not be hidden away in secret, but rather put on display for the entire world to witness [רד״ק, מצודת דוד, מלבי״ם].
Beyond this public disgrace, God declares that He will take vengeance. The primary approach among commentators is that this is a direct divine retribution for the evil and immense suffering that Babylon inflicted upon the people of Israel [רד״ק, מצודת דוד, מלבי״ם, שד״ל].
The absolute nature of this vengeance is understood in several distinct ways. One approach views God's action as entirely independent; He will personally carry out the retribution without needing to ask or rely on any human to act on His behalf [רש״י, מלבי״ם]. Conversely, God will absolutely refuse any pleas, appeasements, or begging from anyone attempting to seek mercy for Babylon to halt the punishment [מצודת דוד, רד״ק, אבן עזרא].
Another perspective focuses on the unstoppable force of this event. God will not encounter anyone capable of standing in His way or stopping the punishment [שד״ל, אבן עזרא]. Unlike the people of Israel, who have a redeemer, Babylon will have no one to save her [שד״ל]. Furthermore, God will not encounter a single person who does not actively rejoice in Babylon's ultimate collapse [אבן עזרא].
Finally, looking at the nature of the strike itself, the punishment will not be a typical blow delivered by a human, but rather a uniquely divine retribution [רד״ק]. An alternative view suggests that this specific vengeance will uniquely unfold without the shedding of blood [ביאור שטיינזלץ].
