Leviticus 7:18-28

18 And the Lord spoke to Moses, saying,
19 Thou shalt also speak to the children of Israel, saying, He that offers a sacrifice of peace-offering, shall bring his gift to the Lord also from the sacrifice of peace-offering.
20 His hands shall bring the burnt-offerings to the Lord; the fat which is on the breast and the lobe of the liver, he shall bring them, so as to set them for a gift before the Lord.
21 And the priest shall offer the fat upon the altar, and the breast shall be Aaron's and his sons,
22 and ye shall give the right shoulder for a choice piece to the priest of your sacrifices of peace-offering.
23 He that offers the blood of the peace-offering, and the fat, of the sons of Aaron, his shall be the right shoulder for a portion.
24 For 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 from the children of Israel.
25 This is the anointing of Aaron, and the anointing of his sons, of the burnt-offerings of the Lord, in the day in which he brought them forward to minister as priests to the Lord;
26 as the Lord commanded to give to them in the day in which he anointed them of the sons of Israel, a perpetual statute through their generations.
27 This 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;
28 as the Lord commanded Moses in the mount Sina, in the day in which he commanded the children of Israel to offer their gifts before the Lord in the wilderness of Sina.
