Leviticus 7:35-38

35This is the anointing-portion of Aaron, and the anointing-portion of his sons, out of the offerings of Jehovah made by fire, in the day when he presented them to minister unto Jehovah in the priest’s office; 36which Jehovah commanded to be given them of the children of Israel, in the day that he anointed them. It is their portion for ever throughout their generations.

37This is the law of the burnt-offering, of the meal-offering, and of the sin-offering, and of the trespass-offering, and of the consecration, and of the sacrifice of peace-offerings; 38which Jehovah commanded Moses in mount Sinai, in the day that he commanded the children of Israel to offer their oblations unto Jehovah, in the wilderness of Sinai.
