ישעיהו, פרק י״ד, פסוק כ״א

A dramatic turning point occurs as the nations of the world issue a unified call to completely wipe out the Babylonian royal dynasty. Their target is specifically Belshazzar and his household, who are held accountable for the severe sins committed by his father and his grandfather, Nebuchadnezzar [אבן עזרא]. The nations urge one another to prepare a place of slaughter for the king's sons [מצודת ציון].

This call for total elimination stems from two main motives. First, it serves as a direct punishment for the past sins of their ancestors, who brought ruin to the world. Second, it is a necessary measure to prevent future danger. There is a deep fear that if the sons survive, they will follow in the wicked footsteps of their fathers, claim ownership of the land through their royal inheritance, and unleash further devastation [רד״ק, מלבי״ם]. Therefore, they must be killed to ensure they never rise to power.

The ultimate goal of stopping these heirs is tied to a warning about what will eventually fill the world. Commentators offer different perspectives on the exact nature of this outcome. One approach suggests that if the king's sons were to take power, they would stir up deep hatred and fill the world with enemies, oppression, and destruction [רש״י, רד״ק, אבן עזרא]. Such a rise to power would simply invite more ruin [ביאור שטיינזלץ].

However, the primary approach among commentators understands this outcome in terms of actual physical cities. Within this view, there are differing opinions on whether filling the world with cities is a positive or negative result. Most agree that it represents a positive vision that can only be achieved by destroying the royal bloodline. With the heirs removed and unable to inherit the land, exiled populations will finally be able to return home. The world will once again be filled with settled, flourishing cities, reversing the legacy of the Babylonian ancestors who turned the world's settlements into wastelands [רש״י, רד״ק, מצודת דוד, מלבי״ם, אבן עזרא]. Conversely, a unique perspective argues that filling the world with cities is exactly the negative outcome the nations wish to avoid. According to this view, if these arrogant kings were to rise and take the land, they would steal the properties of countless families simply to build unnecessary cities named after themselves, driven purely by vanity and pride [שד״ל].
