Leviticus 6:25-26

CAB(i) 25 Speak to Aaron and to his sons, saying, This is the law of the sin-offering: in the place where they slay the whole burnt offering, they shall slay the sin-offerings before the Lord: they are most holy. 26 The priest that offers it shall eat it; in a holy place it shall be eaten, in the court of the tabernacle of witness.
