Leviticus 7:23-32

23“Tell the Israelites: You are not to eat any fat of an ox, a sheep, or a goat.

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

25If anyone eats animal fat from a food offering presented to the Lord, the person who eats it is to be cut off from his people.

26Wherever you live, you must not eat the blood of any bird or animal.

27Whoever eats any blood is to be cut off from his people.”

28The Lord spoke to Moses:

29“Tell the Israelites: The one who presents a fellowship sacrifice to the Lord is to bring an offering to the Lord from his sacrifice.

30His own hands will bring the food offerings to the Lord. He will bring the fat together with the breast. The breast is to be presented as a presentation offering before the Lord.

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

32You are to give the right thigh to the priest as a contribution from your fellowship sacrifices.
