Leviticus 7:24-33

²⁴The fat of an animal that died without being a sacrifice, or the fat of an animal torn by wild animals, may be used for other purposes, but you must certainly not eat it.

²⁵Whoever eats the fat of an animal that men can offer as a sacrifice by fire to Yahweh, that person must be cut off from his people.

²⁶You must eat no blood whatsoever in any of your houses, whether it is from a bird or an animal.

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

²⁸So Yahweh spoke to Moses and said,

²⁹“Speak to the people of Israel and say, 'He who offers the sacrifice of a peace offering to Yahweh must bring part of his sacrifice to Yahweh.

³⁰The offering for Yahweh to be made by fire, his own hands must bring it. He must bring the fat with the breast, so that the breast may be waved as a wave offering before Yahweh.

³¹The priest must burn the fat on the altar, but the breast will belong to Aaron and his descendants.

³²You must give the right thigh to the priest as an offering presented out of the sacrifice of your peace offerings.

³³The priest, one of Aaron's descendants, who offers the blood of the peace offerings and the fat—he will have the right thigh as his share of the offering.
