21 It shall be made with oil in a griddle. When it is soaked, you shall bring it in. You shall offer the meal offering in baked pieces for a pleasant aroma to Yahweh. 22 The anointed priest that will be in his place from among his sons shall offer it. By a statute forever, it shall be wholly burnt to Yahweh. 23 Every meal offering of a priest shall be wholly burned. It shall not be eaten.”

24 Yahweh spoke to Moses, saying, 25 “Speak to Aaron and to his sons, saying, ‘This is the law of the sin offering: in the place where the burnt offering is killed, the sin offering shall be killed before Yahweh. It is most holy. 26 The priest who offers it for sin shall eat it. It shall be eaten in a holy place, in the court of the Tent of Meeting. 27 Whatever shall touch its flesh shall be holy. When there is any of its blood sprinkled on a garment, you shall wash that on which it was sprinkled in a holy place. 28 But the earthen vessel in which it is boiled shall be broken; and if it is boiled in a bronze vessel, it shall be scoured, and rinsed in water. 29 Every male among the priests shall eat of it: it is most holy. 30 No sin offering, of which any of the blood is brought into the Tent of Meeting to make atonement in the Holy Place, shall be eaten: it shall be burned with fire.

Matthew Henry's Commentary on Leviticus 6:21-30

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.
