Leviticus 7:29-36

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

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 food offerings to the LORD for Aaron and his sons since the day they were presented to serve the LORD as priests. 36On the day they were anointed, the LORD commanded that this be given them by the sons of Israel. It is a permanent portion for the generations to come.
