Leviticus 7:20-34

20But if anyone who is unclean eats meat from the peace offering that belongs to the LORD, that person must be cut off from his people. 21If one touches anything unclean, whether human uncleanness, an unclean animal, or any unclean, detestable thing, and then eats any of the meat of the peace offering that belongs to the LORD, that person must be cut off from his people.”

22Then the LORD said to Moses, 23“Speak to the Israelites and say, ‘You are not to eat any of the fat of an ox, a sheep, or a goat. 24The fat of an animal found dead or mauled by wild beasts may be used for any other purpose, but you must not eat it.

25If anyone eats the fat of an animal from which a food offering may be presented to the LORD, the one who eats it must be cut off from his people. 26You must not eat the blood of any bird or animal in any of your dwellings. 27If anyone eats blood, that person must be cut off from his people.’”

28Then the LORD said to Moses, 29“Speak to the Israelites and say, ‘Anyone who presents a peace offering to the LORD must bring it as his sacrifice to the LORD. 30With his own hands he is to bring the food offerings to the LORD; he shall bring the fat, together with the breast, and wave the breast as a wave offering before the LORD.

31The priest is to burn the fat on the altar, but the breast belongs to Aaron and his sons. 32And you are to give the right thigh to the priest as a contribution from your peace offering. 33The son of Aaron who presents the blood and fat of the peace offering shall have the right thigh as a portion.

34I have taken from the sons of Israel the breast of the wave offering and the thigh of the contribution of their peace offerings, and I have given them to Aaron the priest and his sons as a permanent portion from the sons of Israel.’”
