Leviticus 7:35-38

35This is the portion of the anointing of Aaron, and of the anointing of his sons, out of the offerings of Yhwh made by fire, in the day when he presented them to minister unto Yhwh in the priest’s office; 36Which Yhwh commanded to be given them of the children of Israel, in the day that he anointed them, by a statute for ever throughout their generations. 37This is the law of the burnt offering, of the grain offering, and of the sin offering, and of the trespass offering, and of the consecrations, and of the sacrifice of the peace offerings; 38Which Yhwh commanded Moses in mount Sinai, in the day that he commanded the children of Israel to offer their oblations unto Yhwh, in the wilderness of Sinai.
