Leviticus 6:19-28

19 The Lord gave Moses the following regulations
20 for the ordination of an Aaronite priest. On the day he is ordained, he shall present as an offering to the Lord two pounds of flour (the same amount as the daily grain offering), half in the morning and half in the evening.
21 It is to be mixed with oil and cooked on a griddle and then crumbled and presented as a grain offering, an odor pleasing to the Lord.
22 For all time to come this offering is to be made by every descendant of Aaron who is serving as High Priest. It shall be completely burned as a sacrifice to the Lord.
23 No part of a grain offering that a priest makes may be eaten; all of it must be burned.
24 The Lord commanded Moses
25 to give Aaron and his sons the following regulations for sin offerings. The animal for a sin offering shall be killed on the north side of the altar, where the animals for the burnt offerings are killed. This is a very holy offering.
26 The priest who sacrifices the animal shall eat it in a holy place, the courtyard of the Tent of the Lord's presence.
27 Anyone or anything that touches the flesh of the animal will be harmed by the power of its holiness. If any article of clothing is spattered with the animal's blood, it must be washed in a holy place.
28 Any clay pot in which the meat is boiled must be broken, and if a metal pot is used, it must be scrubbed and rinsed with water.
