Leviticus 7:23-32

23“Speak to the children of Israel, saying, ‘You shall not eat any fat from an ox, a sheep, or a goat.

24The fat of an animal which dies [of natural causes] and the fat of one which is torn [to pieces by a predator] may be put to any other use, but under no circumstances are you to eat it.

25For whoever eats the fat of the animal from which an offering by fire is presented to the Lord, that person who eats shall be cut off from his people [excluding him from the atonement made for them].

26Moreover, you are not to eat any blood [of any kind], whether of bird or animal, in any of your dwelling places.

27Whoever eats any blood, that person shall be cut off from his people.’ ”

28Then the Lord spoke to Moses, saying,

29“Speak to the children of Israel, saying, ‘He who offers the sacrifice of his peace offerings to the Lord shall bring his offering to the Lord from the sacrifice of his peace offerings.

30With his own hands he is to bring offerings by fire to the Lord; he shall bring the fat with the breast, so that the breast may be presented as a wave offering before the Lord.

31The priest shall offer up the fat in smoke on the altar, but the breast shall be for Aaron and his sons.

32You shall give the right thigh to the priest as a contribution from the sacrifices of your peace offerings.
