Leviticus 7:27 (KJV)

And the LORD spake unto Moses, saying,

Speak unto the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat.

And the fat of the beast that dieth of itself, and the fat of that which is torn with beasts, may be used in any other use: but ye shall in no wise eat of it.

For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto the LORD, even the soul that eateth it shall be cut off from his people.

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

And the LORD spake unto Moses, saying,

Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace offerings unto the LORD shall bring his oblation unto the LORD of the sacrifice of his peace offerings.

His own hands shall bring the offerings of the LORD made by fire, the fat with the breast, it shall he bring, that the breast may be waved for a wave offering before the LORD.

And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'.

And the right shoulder shall ye give unto the priest for an heave offering of the sacrifices of your peace offerings.
