Commentators unanimously highlight that the punishments in this verse directly counteract the goals of the people's sin. They cheated to get more, but God curses their efforts so they "eat, but not be satisfied." Scholars like John Calvin explain this isn't just a lack of food, but God supernaturally removing its ability to nourish. This demonstrates that any gain acquired through injustice is ultimately futile and unsatisfying because God Himself will oppose it.
