Leviticus 7:35-38

35‘This is the 1allotment to Aaron and the allotment to his sons from the offerings by fire to the Lord, on that day when he presented them to serve as priests to the Lord. 362These the Lord had commanded to be given them from the sons of Israel on the day that He 3anointed them. It is their allotted portion forever throughout their generations.’”

37This is the law of the burnt offering, the grain offering, the sin offering and the guilt offering, and 4the ordination offering and the sacrifice of peace offerings, 385which the Lord commanded Moses on Mount Sinai on the day that He commanded the sons of Israel to 6present their offerings to the Lord in the wilderness of Sinai.
