A devastating prophecy foretells the complete collapse of the defense strategies of Judah and Jerusalem, culminating in a crushing military defeat and profound disgrace. God intends to entirely nullify and ruin the plans the people have relied upon. The primary approach among commentators highlights a poetic connection to a flask mentioned in the broader context of this prophecy. Just as a flask is meant to have its contents poured out, God will break open and completely drain the plans and strategies of the nation [רש״י, מצודת ציון, מלבי״ם, ביאור שטיינזלץ]. This profound emptying represents utter desolation and destruction [רד״ק].
With their counsel completely drained, the people will be left entirely helpless. They will be unable to come up with any new advice, tactic, or solution to escape the approaching ruin [מצודת דוד].
The aftermath of this defeat brings a horrific reality, designed to show the ultimate depth of their humiliation. Those who fall by the sword will be denied the dignity of a proper burial. Instead, their bodies will be abandoned in the open, left as food for the birds of the sky and the wild beasts of the earth [מצודת דוד].
