Matthew Henry Commentary Leviticus 6:24-30

"And Jehovah spake unto Moses, saying, Speak unto Aaron and to his sons, saying, This is the law of the sin-offering: in the place where the burnt-offering is killed shall the sin-offering be killed before Jehovah: it is most holy. The priest that offereth it for sin shall eat it: in a holy place shall it be eaten, in the court of the tent of meeting. Whatsoever shall touch the flesh thereof shall be holy; and when there is sprinkled of the blood thereof upon any garment, thou shalt wash that whereon it was sprinkled in a holy place. But the earthen vessel wherein it is boiled shall be broken; and if it be boiled in a brazen vessel, it shall be scoured, and rinsed in water. Every male among the priests shall eat thereof: it is most holy. And no sin-offering, whereof any of the blood is brought into the tent of meeting to make atonement in the holy place, shall be eaten: it shall be burnt with fire." — Leviticus 6:24-30 (ASV)

The blood of the sin-offering was to be washed out of the clothes on which it happened to be sprinkled. This signified the regard we should have for 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 was an earthenware one; but if a bronze one, it must be well washed.

This showed that the defilement was not completely taken away by the offering, but the blood of Christ thoroughly cleanses from all sin. All these rules demonstrate 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 willing to be made a sin-offering for us, and so secure our pardon for continual sins and failings.

He that knew no sin was made sin (that is, a sin-offering) for us (2 Corinthians 5:21). Therefore, we have pardon, and not only pardon, but also power against sin (Romans 8:3).
