Do Not Eat Blood...and other unnatural things, Leviticus 17...

Therefore I said to the children of Israel, ‘No one among you shall eat blood, nor shall any stranger who dwells among you eat blood.’ for it is the life of all flesh. Its blood sustains its life. Therefore I said to the children of Israel, ‘You shall not eat the blood of any flesh, for the life of all flesh is its blood. Whoever eats it shall be cut off.’ You shall not lie with a male as with a woman. It is an abomination. Nor shall you mate with any animal, to defile yourself with it. Nor shall any woman stand before an animal to mate with it. It is perversion. ‘Do not defile yourselves with any of these things; for by all these the nations are defiled, which I am casting out before you.
