Leviticus 7:21-33

²¹And whatsoever soul shall touch any unclean thing, either of the uncleanness of a man, or of unclean quadrupeds, or any unclean abominable thing, and shall eat of the flesh of the sacrifice of the peace-offering, which is the Lord's, that soul shall perish from his people.

²²And the Lord spoke to Moses, saying,

²³Speak to the children of Israel, saying, Ye shall eat no fat of oxen or sheep or goats.

²⁴And the fat of such animals as have died of themselves, or have been seized of beasts, may be employed for any work; but it shall not be eaten for food.

²⁵Every one that eats fat off the beasts, from which he will bring a burnt-offering to the Lord—that soul shall perish from his people.

²⁶Ye shall eat no blood in all your habitations, either of beasts or of birds.

²⁷Every soul that shall eat blood, that soul shall perish from his people.

²⁸And the Lord spoke to Moses, saying,

²⁹Thou shalt also speak to the children of Israel, saying, He that offers a sacrifice of peace-offering, shall bring his gift to the Lord also from the sacrifice of peace-offering.

³⁰His hands shall bring the burnt-offerings to the Lord; the fat which is on the breast and the lobe of the liver, he shall bring them, so as to set them for a gift before the Lord.

³¹And the priest shall offer the fat upon the altar, and the breast shall be Aaron's and his sons,

³²and ye shall give the right shoulder for a choice piece to the priest of your sacrifices of peace-offering.

³³He that offers the blood of the peace-offering, and the fat, of the sons of Aaron, his shall be the right shoulder for a portion.
