Leviticus 7:35-38

35This is [the portion] of the anointing of Aaron and of the anointing of his sons, from Jehovah's offerings by fire, in the day [when] he presented them to serve Jehovah as priests, 36which Jehovah commanded to be given them by the children of Israel in the day that he anointed them: [it is] an everlasting statute, throughout their generations. 37This is the law of the burnt-offering, of the oblation, and of the sin-offering, and of the trespass-offering, and of the consecration-offering, and of the sacrifice of peace-offering, 38which Jehovah commanded Moses in mount Sinai, in the day that he commanded the children of Israel to present their offerings to Jehovah, in the wilderness of Sinai.
