ירמיהו, פרק נ״א, פסוק כ״ח

A massive military gathering is set in motion against the empire of Babylon. A sweeping call goes out to summon the nations and ready them for the impending attack, focusing specifically on the chain of command within the Median empire that will lead the charge. This command to prepare acts as a formal invitation, rallying the forces for the historic events about to unfold [רד״ק].

The summons is directed at the highest levels of leadership, specifically the kings of Media. This points directly to Darius and his son-in-law Cyrus, who would later inherit the throne from him [מצודת דוד]. Beyond the kings, the call reaches down through the various ranks of the government. It rallies the local rulers and senior officials, sweeping up every level of authority within the kingdom [מצודת ציון, ביאור שטיינזלץ]. Ultimately, this call to arms leaves no area untouched, encompassing all the territories and lands that fall under the vast rule of the Median king [מצודת דוד, ביאור שטיינזלץ].
