Leviticus 7:35-38

35This is the portion of the food offerings to the LORD for Aaron and his sons since the day they were presented to serve the LORD as priests. 36On the day they were anointed, the LORD commanded that this be given them by the sons of Israel. It is a permanent portion for the generations to come.

37This is the law of the burnt offering, the grain offering, the sin offering, the guilt offering, the ordination offering, and the peace offering, 38which the LORD gave Moses on Mount Sinai on the day He commanded the Israelites to present their offerings to the LORD in the Wilderness of Sinai.
