Leviticus 6:25-26

²⁵(6-18) Speak unto Aaron and to his sons, saying: This is the law of the sin-offering: in the place where the burnt-offering is killed shall the sin-offering be killed before the LORD; it is most holy.

²⁶(6-19) The 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.
