Leviticus 6:20-22

20“This is the offering that Aaron and his sons must present to the LORD on the day he is anointed: a tenth of an ephah of fine flour1 as a regular grain offering, half of it in the morning and half in the evening. 21It shall be prepared with oil on a griddle;2 you are to bring it well-kneaded and present it as a grain offering broken3 in pieces, a pleasing aroma to the LORD. 22The priest, who is one of Aaron’s sons and will be anointed to take his place, is to prepare it. As a permanent portion for the LORD, it must be burned completely.
