Leviticus 6:20-22

20“This is the offering which Aaron and his sons are to present to the Lord on the day when he is anointed: the tenth of an ephah of fine flour as a regular grain offering, half of it in the morning and half of it in the evening.

21It 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 sweet and soothing aroma to the Lord.

22The priest from among the sons of Aaron who is anointed in his place shall offer it. By a permanent statute it shall be entirely offered up in smoke to the Lord.
