Warning: Using contemporary science and philosophy to explain the Torah may soon render your interpretation obsolete.

In the creation story, God tells humans to eat plants. Only after the flood, does God permit them to eat animals. Interpreters have understood this to mean that vegetarianism was God’s original plan for humanity. Gersonides found the claim that God changed His mind scandalous, but this is more about countering Christian claims than the simple meaning of the text.
