Leviticus 7:28

24 The fat of an animal found dead or mauled by wild beasts may be used for any other purpose, but you must not eat it.

25 If anyone eats the fat of an animal from which an offering made by fire may be presented to the LORD, the one who eats it must be cut off from his people.

26 You must not eat the blood of any bird or animal in any of your dwellings.

27 If anyone eats blood, that person must be cut off from his people.’”

28 Then 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.

30 With his own hands he is to bring the offerings made by fire to the LORD; he shall bring the fat, together with the breast, and wave the breast as a wave offering before the LORD.

31 The priest is to burn the fat on the altar, but the breast belongs to Aaron and his sons.

32 And you are to give the right thigh to the priest as a contribution from your peace offering.
