Genesis 9:3-5

Revised Standard Version Catholic Edition

³ Every moving thing that lives shall be food for you; and as I gave you the green plants, I give you everything. ⁴ Only you shall not eat flesh with its life, that is, its blood. ⁵ For your lifeblood I will surely require a reckoning; of every beast I will require it and of man; of every man’s brother I will require the life of man.
