Leviticus 6:23-26 New International Version (NIV)

23. Every grain offering of a priest shall be burned completely; it must not be eaten.”

24. The Lord said to Moses,

25. “Say to Aaron and his sons: ‘These are the regulations for the sin offering: The sin offering is to be slaughtered before the Lord in the place the burnt offering is slaughtered; it is most holy.

26. The priest who offers it shall eat it; it is to be eaten in the sanctuary area, in the courtyard of the tent of meeting.
