21 It 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 . 22 In 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. 23 All such grain offerings of a priest must be burned up entirely. None of it may be eaten."
24 Then the Lord said to Moses, 25 "Give Aaron and his sons the following instructions regarding the sin offering. The animal given as an offering for sin is a most holy offering, and it must be slaughtered in the Lord 's presence at the place where the burnt offerings are slaughtered. 26 The priest who offers the sacrifice as a sin offering must eat his portion in a sacred place within the courtyard of the Tabernacle. 27 Anyone or anything that touches the sacrificial meat will become holy. If any of the sacrificial blood spatters on a person's clothing, the soiled garment must be washed in a sacred place. 28 If a clay pot is used to boil the sacrificial meat, it must then be broken. If a bronze pot is used, it must be scoured and thoroughly rinsed with water. 29 Any male from a priest's family may eat from this offering; it is most holy. 30 But the offering for sin may not be eaten if its blood was brought into the Tabernacle as an offering for purification in the Holy Place. It must be completely burned with fire.

Commentary on Leviticus 6:14-23
(Read Leviticus 6:14-23)
The law of the burnt-offerings put upon the priests a great deal of care and work; the flesh was wholly burnt, and the priests had nothing but the skin. But most of the meat-offering was their own. It is God's will that his ministers should be provided with what is needful.
Commentary on Leviticus 6:24-30
(Read Leviticus 6:24-30)
The blood of the sin-offering was to be washed out of the clothes on which it should happen to be sprinkled, which signified the regard we ought to have to the blood of Christ, not counting it a common thing. The vessel in which the flesh of the sin-offering was boiled must be broken, if it were an earthen one; but if a brazen one, well washed. This showed that the defilement was not wholly taken away by the offering; but the blood of Christ thoroughly cleanses from all sin. All these rules set forth the polluting nature of sin, and the removal of guilt from the sinner to the sacrifice. Behold and wonder at Christ's love, in that he was content to be made a sin-offering for us, and so to procure our pardon for continual sins and failings. He that knew no sin was made sin (that is, a sin-offering) for us, Romans 8:3.
