Leviticus 6:20-25

²⁰This is the offering which Aaron and his sons are to make to the Lord on the day when he is made a priest: the tenth part of an ephah of the best meal for a meal offering for ever; half of it in the morning and half in the evening.

²¹Let it be made with oil on a flat plate; when it is well mixed and cooked, let it be broken and taken in as a meal offering, for a sweet smell to the Lord.

²²And the same offering is to be given by that one of his sons who takes his place as priest; by an order for ever, all of it is to be burned before the Lord.

²³Every meal offering offered for the priest is to be completely burned: nothing of it is to be taken for food.

²⁴And the Lord said to Moses,

²⁵Say to Aaron and his sons, This is the law for the sin-offering: the sin-offering is to be put to death before the Lord in the same place as the burned offering; it is most holy.
