Leviticus 6:25-26

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

²⁶The priest who offers it for sin shall eat it. It shall be eaten in a holy place, in the court of the Tent of Meeting.
