Leviticus 7:20-32

²⁰If any one that is defiled shall eat of the flesh of the sacrifice of peace offerings, which is offered to the Lord, he shall be cut off from his people.

²¹And he that hath touched the uncleanness of man, or of beast, or of any thing that can defile, and shall eat of such kind of flesh, shall be cut off from his people.

²²And the Lord spoke to Moses, saying:

²³Say to the children of Israel: The fat of a sheep, and of an ox, and of a goat you shall not eat.

²⁴The fat of a carcass that hath died of itself, and of a beast that was caught by another beast, you shall have for divers uses.

²⁵If any man eat the fat that should be offered for the burnt sacrifice of the Lord, he shall perish out of his people.

²⁶Moreover you shall not eat the blood of any creature whatsoever, whether of birds or beasts.

²⁷Every one that eateth blood, shall perish from among the people.

²⁸And the Lord spoke to Moses, saying:

²⁹Speak to the children of Israel, saying: He that offereth a victim of peace offerings to the Lord, let him offer therewith a sacrifice also, that is, the libations thereof.

³⁰He shall hold in his hands the fat of the victim, and the breast: and when he hath offered and consecrated both to the Lord, he shall deliver them to the priest,

³¹Who shall burn the fat upon the altar, but the breast shall be Aaron’s and his sons’.

³²The right shoulder also of the victims of peace offerings shall fall to the priest for firstfruits.
