Leviticus 6:19-23

19The Lord also said to Moses, 20“This is the offering Aaron and his sons are to bring to the Lord on the day he is anointed: a tenth of an ephah of the finest flour as a regular grain offering, half of it in the morning and half in the evening. 21It must be prepared with oil on a griddle; bring it well-mixed and present the grain offering broken in pieces as an aroma pleasing to the Lord. 22The son who is to succeed him as anointed priest shall prepare it. It is the Lord’s perpetual share and is to be burned completely. 23Every grain offering of a priest shall be burned completely; it must not be eaten.”
