Genesis 1:29

ולכל חית הארץ AND TO EVERY BEAST OF THE EARTH — Scripture places cattle and beasts on a level with them (human beings: that is, it places all alike in the same category) with regard to food, and did not permit Adam to kill any creature and eat its flesh, but all alike were to eat herbs. But when the era of the “Sons of Noah” began He permitted them to eat meat, for it is said, (Genesis 9:3) “every moving thing that lives should be for food for yourselves … “even as the herb” that I permitted to the first man, so do “I give to you everything” (Sanhedrin 59b).

וַיֹּ֣אמֶר אֱלֹהִ֗ים הִנֵּה֩ נָתַ֨תִּי לָכֶ֜ם אֶת־כׇּל־עֵ֣שֶׂב ׀ זֹרֵ֣עַ זֶ֗רַע אֲשֶׁר֙ עַל־פְּנֵ֣י כׇל־הָאָ֔רֶץ וְאֶת־כׇּל־הָעֵ֛ץ אֲשֶׁר־בּ֥וֹ פְרִי־עֵ֖ץ זֹרֵ֣עַ זָ֑רַע לָכֶ֥ם יִֽהְיֶ֖ה לְאׇכְלָֽה׃

And God said, Behold I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, on which is the fruit yielding seed; to you it shall be for food.
