Leviticus 7:36

He among the sons of Aaron who offers the blood of the peace offerings, and the fat, shall have the right thigh for a portion.

For the waved breast and the heaved thigh I have taken from the children of Israel out of the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their portion forever from the children of Israel.’”

This is the consecrated portion of Aaron, and the consecrated portion of his sons, out of the offerings of the LORD made by fire, in the day when he presented them to minister to the LORD in the priest’s office;

This is the law of the burnt offering, the meal offering, the sin offering, the trespass offering, the consecration, and the sacrifice of peace offerings

which the LORD commanded Moses in Mount Sinai in the day that he commanded the children of Israel to offer their offerings to the LORD, in the wilderness of Sinai.
