Leviticus 7:31-38

31And the priest shall offer up the fat in smoke on the altar, but 1the breast shall belong to Aaron and to his sons. 32And you shall give 2the right thigh to the priest as a 3contribution from the sacrifices of your peace offerings. 33The one among the sons of Aaron who offers the blood of the peace offerings and the fat, the right thigh shall be his as his portion. 34For I have taken from the sons of Israel 4the breast of the wave offering and the thigh of the 5contribution from the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their allotted portion forever from the sons of Israel.

35‘This is the 6allotment to Aaron and the allotment to his sons from the offerings by fire to the Lord, on that day when he presented them to serve as priests to the Lord. 367These the Lord had commanded to be given them from the sons of Israel on the day that He 8anointed them. It is their allotted portion forever throughout their generations.’”

37This is the law of the burnt offering, the grain offering, the sin offering and the guilt offering, and 9the ordination offering and the sacrifice of peace offerings, 3810which the Lord commanded Moses on Mount Sinai on the day that He commanded the sons of Israel to 11present their offerings to the Lord in the wilderness of Sinai.
