Leviticus 6:21

17It shall not be baked with yeast. I have given it as their portion of my offerings made by fire. It is most holy, as are the sin offering and the trespass offering.

18Every male among the children of Aaron shall eat of it, as their portion forever throughout your generations, from the offerings of the LORD made by fire. Whoever touches them shall be holy.’”

19The LORD spoke to Moses, saying,

20“This is the offering of Aaron and of his sons, which they shall offer to the LORD in the day when he is anointed: one tenth of an ephah of fine flour for a meal offering perpetually, half of it in the morning, and half of it in the evening.

21It shall be made with oil in a griddle. When it is soaked, you shall bring it in. You shall offer the meal offering in baked pieces for a pleasant aroma to the LORD.

22The anointed priest that will be in his place from among his sons shall offer it. By a statute forever, it shall be wholly burned to the LORD.

23Every meal offering of a priest shall be wholly burned. It shall not be eaten.”

24The LORD spoke to Moses, saying,

25“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.
