Commentators unanimously highlight the core tragedy of this verse: Judah witnessed the downfall of her sister nation, Israel. She saw Israel's idolatry and the resulting punishment from God—a 'bill of divorce' in the form of national exile. Yet, as Charles Spurgeon notes, instead of fearing God and repenting, Judah deliberately walked into the same fire that had consumed her sister. This serves as a solemn warning to learn from the consequences of sin we see in others.
