The vision of the ultimate future offers a profound picture of peace, where the violent laws of nature are entirely rewritten. The primary approach among commentators is that this represents a literal transformation in the animal kingdom [אבן עזרא, מלבי״ם]. Natural predators will abandon their hunting instincts and adopt a plant based diet. Wolves and lambs will graze side by side in harmony [שטיינזלץ, מצודת דוד], and lions will eat straw just like cattle, completely losing their need for meat [רש״י, מלבי״ם].
Amidst this broad transformation, the snake experiences a different reality. It will continue to consume dust, fulfilling the original decree placed upon it at the dawn of creation [מצודת דוד, אבן עזרא]. Because dust is endlessly abundant, the snake will be fully satisfied and will no longer seek to bite humans [רש״י, שד״ל]. Offering a slightly different conceptual angle, [רד״ק] explains that because the Israelites will be filled with the knowledge of God, they will no longer be spiritually equated with dust. As a result, the snake will have no power to control or harm them. Ultimately, all creatures will cease to cause pain or ruin. A precise distinction is drawn regarding this new peaceful state: predators, which previously caused harm simply to feed themselves, will no longer do bad things, while the snake, which bit purely for the sake of destruction, will no longer destroy [מלבי״ם]. This newfound peace among the animals also serves as a reflection of human society, indicating that people will finally stop harming one another [שד״ל]. Commentators agree that these promises are destined to unfold specifically within the Land of Israel [אבן עזרא, רד״ק, מצודת דוד, שד״ל].
Beyond the literal meaning, another approach reads the animals as a deep historical and national metaphor. One perspective suggests they represent the reunified tribes of Israel. The wolf, symbolizing Benjamin, and the lion, representing Judah and Dan, will live in perfect peace with the other tribes, who are compared to the lamb and the cattle, representing Joseph. Alternatively, the imagery illustrates how the mighty tribes of Israel will consume their enemies, such as Esau, who are likened to mere straw [רש״י, אברבנאל].
The most comprehensive symbolic approach views this harmony as the ultimate destiny of the world empires [אברבנאל]. Historical enemies will finally find peace together, with the wolf representing Persia and the lamb representing Greece. The lion, symbolizing Babylon and Ishmael, will come to share common beliefs with the cattle, which represents the people of Israel. However, while Israel will consume the nourishing grain itself, the lion will settle for the lesser straw. Once again, the snake stands apart, representing Edom and Rome. While other nations will experience global peace, Edom, which sought to destroy Israel and dominate the world, will be excluded from this blessing. Its ultimate punishment will be eternal disgrace, a complete loss of its wisdom, and a continuous diet of dust as it remains trapped in its false beliefs [אברבנאל].
