Leviticus 6:19-22

19And the Lord spake unto Moses, saying, 20This is the offering of Aaron and of his sons, which they shall offer unto the Lord in the day when he is anointed; the tenth part of an ephah of fine flour for a meat offering perpetual, half of it in the morning, and half thereof at night. 21In a pan it shall be made with oil; and when it is baken, thou shalt bring it in: and the baken pieces of the meat offering shalt thou offer for a sweet savour unto the Lord. 22And the priest of his sons that is anointed in his stead shall offer it: it is a statute for ever unto the Lord; it shall be wholly burnt.
