Leviticus 7:30-36

7:30 With his own hands he must bring the Lord’s gifts. He must bring the fat with the breast to wave the breast as a wave offering before the Lord, 7:31 and the priest must offer the fat up in smoke on the altar, but the breast will belong to Aaron and his sons. 7:32 The right thigh you must give as a contribution offering to the priest from your peace offering sacrifices. 7:33 The one from Aaron’s sons who presents the blood of the peace offering and fat will have the right thigh as his share, 7:34 for the breast of the wave offering and the thigh of the contribution offering I have taken from the Israelites out of their peace offering sacrifices and have given them to Aaron the priest and to his sons from the people of Israel as a perpetual allotted portion.’”

7:35 This is the allotment of Aaron and the allotment of his sons from the Lord’s gifts on the day Moses presented them to serve as priests to the Lord. 7:36 This is what the Lord commanded to give to them from the Israelites on the day Moses anointed them – a perpetual allotted portion throughout their generations.
