This haftarah continues directly from where the previous one left off, with God asking through Jeremiah what wrong the ancestors actually found in Him that they wandered so far away, recalling how He led them through a wilderness of drought and deep darkness into a fruitful land, only to have that same land defiled once they settled it, priests, rulers and prophets alike failing in their responsibilities.
Jeremiah then charges the nation with an offense he treats as almost unprecedented, exchanging their glory, the living God, for something that cannot even help itself, worthless idols, an act the prophet compares unfavorably even to the nations who at least remain loyal to their own gods, however powerless those gods actually are. He describes Israel as a vine planted from choice seed that has degenerated into something wild and worthless.
The haftarah closes urging the people to call out to God as their father even now, despite everything just described, a brief note of possible reconciliation appended to what has otherwise been an extended and severe indictment of the nation's unfaithfulness across its own settled history in the land.
The comparison of Israel to a vine planted from choice seed that has degenerated into something wild is one of several agricultural images Jeremiah returns to across this stretch of his prophecy, treating the nation's decline less as a sudden fall than as a slow corruption of something originally cultivated with care.
