Leviticus 7:30-33

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.
