The answer is: Trees for meat

Deut 20:19-20

When the Israelites surrounded a city, they were commanded not to destroy the trees that produced fruit, particularly those deemed valuable for food—or “trees for meat.” This prohibition showcases an intellectual understanding of sustainability and respect for creation. Instead of claiming all resources recklessly, the Israelites were prompted to think long-term: preserving trees meant ensuring nourishment regardless of conflict.

Interestingly, this reflects a deeper biblical principle: the value of life in all its forms. Trees provide habitat, oxygen, and a refreshment of spirit, just as sacred texts invite us to honor God's creation collectively. In the natural world, trees symbolize growth, vitality, and renewal—a perfect metaphor for the ongoing journey of faith.

Additionally, this echoes ecological principles we continue to learn today. That ancient plea not to destroy resources frivolously resonates with modern conversations about conservation and responsibility toward the earth. The ethos extends beyond politics or economics to align with the care of the world we inhabit.

Looking at Israelite history, the land was believed to flow with "milk and honey," lush and bounteous in provision. Trees were essential—dates, olives, and pomegranates, to name a few. Paying heed to such agricultural wisdom may have contributed directly to the identity and welfare of the community. So, beyond warring strategies, these choices of wisdom invite reflection on gentleness and prudence in our own stewardship over the world today.
