The prophetic message rings out to the nations of the world, urging them to spread and celebrate the news of the Babylonian empire's collapse and the shattering of its belief system. This call is specifically directed at the surrounding nations because Babylon had previously destroyed and wiped out many peoples. Therefore, its downfall serves as a profound source of joy and comfort for them [רד״ק, מצודת דוד].
The news is meant to be broadcast with increasing intensity, starting as ordinary speech, escalating into a public declaration, and culminating in the raising of a flag [מלבי״ם]. This visual signal involves setting up a tall pole with a cloth attached to the top, designed to gather large crowds so they can hear the announcement [רש״י, מצודת דוד, מצודת ציון]. The messengers are commanded not to hide or withhold a single detail regarding the sheer magnitude of the destruction that has taken place [מצודת דוד, מצודת ציון, ביאור שטיינזלץ].
At the heart of this announcement is not merely a military defeat, but the total failure of Babylon's central gods, Bel and Merodach [רש״י, חומת אנך, ביאור שטיינזלץ]. These idols face deep shame and are broken, their disgrace fully exposed by their complete inability to save their worshippers from disaster [מצודת דוד, רד״ק]. In fact, the idols are referred to using a term rooted in the concept of sadness, as they ultimately bring only grief to the hearts of those who cry out to them in times of trouble and receive no answer [מצודת ציון].
The downfall of these deities is described using two distinct expressions of defeat. Some understand this simply as poetic variation, where distinct actions are initially paired with individual idols and then applied to all the statues as a whole [חומת אנך]. However, others point to a deeper, substantive distinction based on what each idol represented. Bel stood for honor, so his specific punishment is the loss of that honor, resulting in profound shame. Merodach, on the other hand, symbolized might and power. Thus, his defeat is characterized by breaking and fear, the absolute opposite of courage [מלבי״ם].
