Leviticus 6:22-26

²²The son of the high priest who is becoming the new high priest from among his sons will offer it. As commanded forever, all of it shall be burned to Yahweh.

²³Every grain offering of the priest will be completely burned up. It must not be eaten.”

²⁴Yahweh spoke to Moses again, saying,

²⁵“Speak to Aaron and to his sons, saying, 'This is the law of the sin offering: The sin offering must be killed at the place where the burnt offering is killed before Yahweh. It is most holy.

²⁶The priest who offers it for sin will eat it. It must be eaten in a holy place in the courtyard of the tent of meeting.
