Leviticus 6:20; Leviticus 6:21

20 "This is the offering that Aaron and his sons shall offer to the LORD on the day when he is anointed: a tenth of an ephah of fine flour as a regular grain offering, half of it in the morning and half in the evening.

21 It shall be made with oil on a griddle. You shall bring it well mixed, in baked pieces like a grain offering, and offer it for a pleasing aroma to the LORD.
