Leviticus 7:35-38

35This is the allotment of Aaron and the allotment of his sons from the Lord’s gifts on the day Moses presented them to serve as priests to the Lord.

36This is what the Lord commanded to give to them from the Israelites on the day Moses anointed them – a perpetual allotted portion throughout their generations.

37This is the law for the burnt offering, the grain offering, the sin offering, the guilt offering, the ordination offering, and the peace offering sacrifice,

38which the Lord commanded Moses on Mount Sinai on the day he commanded the Israelites to present their offerings to the Lord in the wilderness of Sinai.
