Leviticus 6:21-25

It shall be prepared with oil on a griddle. When it is well stirred, you shall bring it. You shall present the grain offering in baked pieces as a soothing aroma to the LORD. The anointed priest who will be in his place among his sons shall offer it. By a permanent ordinance it shall be entirely offered up in smoke to the LORD. So every grain offering of the priest shall be burned entirely. It shall not be eaten.” Then the LORD spoke to Moses, saying, “Speak to Aaron and to his sons, saying, ‘This is the law of the sin offering: in the place where the burnt offering is slain the sin offering shall be slain before the LORD; it is most holy.
