Leviticus 7:35-38

35‘This is the consecrated portion from the offerings by fire to the Lord that was designated for Aaron and his sons on the day he presented them to serve as priests to the Lord.

36The Lord commanded this to be given to the priests by the Israelites on the day that He anointed them. It is their portion perpetually throughout their generations.’ ”

37This is the law of the burnt offering, the grain offering, the sin offering, the guilt offering, the consecration (ordination) offering, and the sacrifice of peace offerings,

38which the Lord commanded Moses at Mount Sinai on the day He commanded the Israelites to present their offerings to the Lord, in the Wilderness of Sinai.
