ירמיהו, פרק כ״ז, פסוק י״ג

A stark warning is delivered to the king and the people, urging them to avoid a tragic and completely unnecessary death by sword, famine, and plague. These severe consequences are predetermined punishments for any nation that refuses to willingly accept the burden of Babylonian rule [מצודת דוד].

The impending doom is a direct decree from God, pronounced against any nation that chooses to rebel and resist this subjugation [מצודת דוד, ביאור שטיינזלץ]. By fighting the Babylonian empire instead of submitting, the people bring these divine judgments upon themselves.
