Tragically, the hope for national repentance voiced by Yirmiyahu in earlier prophecies does not bear any fruits in perek 5. Severe immorality and betrayal of God have seeped into every layer of society, from the simplest of men to the loftiest of leaders. Yerushalayim's destruction quickly approaches...

In perek 6 Yirmiyahu's attempts to reform the nation through prophetic warnings are unsuccessful.  In a continuation to the description of the destruction in perek 4, this perek also discusses the destruction set to arrive from the north. Yirmiyahu's hopes for national improvement have dwindled. Calls for repentance have been replaced with intensified emphasis on God's wrath and the impending destruction.
