Leviticus 6:19-23

19Then the Lord said to Moses,

20“On the day Aaron and his sons are anointed, they must present to the Lord the standard grain offering of two quarts of choice flour, half to be offered in the morning and half to be offered in the evening.

21It must be carefully mixed with olive oil and cooked on a griddle. Then slice this grain offering and present it as a pleasing aroma to the Lord.

22In each generation, the high priest who succeeds Aaron must prepare this same offering. It belongs to the Lord and must be burned up completely. This is a permanent law.

23All such grain offerings of a priest must be burned up entirely. None of it may be eaten.”
