Leviticus 6:19-22

19And the Lord spoke to Moses, saying,

20“This is the offering of Aaron and his sons, which they shall offer to the Lord, beginning on the day when he is anointed: one-tenth of an ephah of fine flour as a daily grain offering, half of it in the morning and half of it at night.

21It 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.

22The 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.
