Leviticus 6:18-21
English Standard Version
19The Lord spoke to Moses, saying,
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.
21It 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.
