God gives man permission to expand his menu. For the first time, it is now permitted to eat meat. This was not the case in paradise (see Genesis 1:29–30). Man is now allowed to eat everything he sees in creation. This also changes man’s relationship to the animals. Now man also becomes a threat to certain animals.
The only restriction imposed on man is that he may not eat the blood of an animal. The blood is equated with the soul, with the life of the animal. The prohibition against eating blood did not occur among Israel only—it is a prohibition that was in effect for all mankind, from Noah onward.
3 Every moving thing that lives shall be food for you. And as I gave you the green plants, I give you everything.
