Leviticus 6:20-25

²⁰“This is the offering that Aaron and his sons are to present to the Lord when they're anointed: a tenth of an ephah of best flour as a usual grain offering, half in the morning and half in the evening.

²¹Cook it with olive oil on a griddle. Bring it well-kneaded and present it as a grain offering broken into pieces, to be accepted by the Lord.

²²It is to be cooked by the priest who is one of Aaron's descendants and who is to be anointed to take his place. In this case since it is permanently allocated to the Lord, it must be burned completely.

²³Every grain offering for a priest is to be burned completely. It must not be eaten.”

²⁴The Lord told Moses,

²⁵“Tell Aaron and his sons that these are the regulations for the sin offering. The sin offering is to be killed where the burnt offering is killed before the Lord, and it is most holy.
