Leviticus 6:22-26

²²And the priest who is anointed of his sons in his stead shall prepare it: it is an everlasting statute; it shall be wholly burned to Jehovah.

²³And every oblation of the priest shall be wholly burned; it shall not be eaten.

²⁴And Jehovah spoke to Moses, saying,

²⁵Speak unto Aaron and to his sons, saying, This is the law of the sin-offering. At the place where the burnt-offering is slaughtered shall the sin-offering be slaughtered before Jehovah: it is most holy.

²⁶The priest that offereth it for sin shall eat it: in a holy place shall it be eaten, in the court of the tent of meeting.
