Leviticus 7:30-32

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.
