Leviticus 6:21-25

It shall be made in a pan with oil. When it is mixed, you shall bring it in. The baked pieces of the grain offering you shall offer for a sweet aroma to the LORD. The priest from among his sons, who is anointed in his place, shall offer it. It is a statute forever to the LORD. It shall be wholly burned. For every grain offering for the priest shall be wholly burned. It shall not be eaten.” Also 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 killed, the sin offering shall be killed before the LORD. It is most holy.
