Leviticus 7:29-32

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 out of the sacrifice of his peace offerings.

³⁰With his own hands he shall bring the offerings of the LORD made by fire. He shall bring the fat with the breast, that the breast may be waved for a wave offering before the LORD.

³¹The priest shall burn the fat on the altar, but the breast shall be Aaron’s and his sons’.

³²The right thigh you shall give to the priest for a heave offering out of the sacrifices of your peace offerings.
