Ibn Ezra on Genesis 1:29/אבן עזרא על בראשית א׳:כ״ט

1AND GOD SAID: BEHOLD I HAVE GIVEN YOU. God permitted mankind and every living thing to eat all herbs. He also permitted man to eat the fruits of the trees and limited the animals and creeping things to green herbs. At this point in time the consumption of flesh was not permitted. That came after the flood.
