Leviticus 7:24-34

²⁴And the fat of a beast that dieth of itself, and the fat of that which is torn by beasts, may be used for any manner of work, but ye shall in no wise eat of it.

²⁵For whosoever eateth the fat of the cattle, of which one can offer an offering made by fire unto the Lord, even the person that eateth it shall be cut off from his people.

²⁶Moreover ye shall eat no manner of blood, in any of your dwellings, whether it be of fowl or of cattle.

²⁷Whatsoever person it be that eateth any manner of blood, even that person shall be cut off from his people.

²⁸And the Lord spoke unto Moses, saying,

²⁹Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace-offering unto the Lord shall bring his oblation unto the Lord from the sacrifice of his peace-offering.

³⁰His own hands shall bring it, as the fire-offerings of the Lord: the fat with the breast shall he bring, the breast that it may be waved for a wave-offering before the Lord.

³¹And the priest shall burn the fat upon the altar; but the breast shall belong to Aaron and to his sons.

³²And the right shoulder shall ye give unto the priest for a heave-offering, of the sacrifices of your peace-offerings.

³³The one that offereth the blood of the peace-offerings and the fat, among the sons of Aaron, shall have the right shoulder for his part.

³⁴For the breast which hath been waved and the shoulder which hath been lifted up have I taken from the children of Israel from the sacrifices of their peace-offerings; and I have given them unto Aaron the priest and unto his sons as a fixed portion for ever from the children of Israel.
