Leviticus 7:36

³⁴For I have taken the wave breast and shoulder of separation from the children of Israel from the sacrifices of your peace offerings, and I have given them to Aaron the priest and his sons, a perpetual ordinance due from the children of Israel.

³⁵This is the anointing of Aaron, and the anointing of his sons, their portion of the burnt offerings of the Lord, in the day in which he brought them forward to minister as priests to the Lord;

— Leviticus 7:36 —

³⁷This is the law of the whole burnt offerings, and of sacrifice, and of sin offering, and of offering for transgression, and of the sacrifice of consecration, and of the sacrifice of peace offering;

³⁸as the Lord commanded Moses in the Mount Sinai, in the day in which he commanded the children of Israel to offer their gifts before the Lord in the wilderness of Sinai.
