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.’”
35This is the portion of the offerings made by fire to the LORD for Aaron and his sons since the day they were presented to serve the LORD as priests.
— Leviticus 7:31-35
