Leviticus 7:35-38

35This is the anointed portion of Aaron and the anointed portion of his sons out of the offerings of Adonai made by fire, on the day when he presented them to serve Adonai in the office of kohen.

36Adonai commanded these to be given to them from Bnei-Yisrael on the day that he anointed them. It is their portion forever throughout their generations.

37This is the Torah of the burnt offering, the grain offering, the sin offering, the trespass offering, the ordination offering, and the sacrifice of fellowship offerings,

38which Adonai commanded Moses at Mount Sinai, on the day He commanded Bnei-Yisrael to present their offerings to Adonai, in the wilderness of Sinai.
