Those verses relate to the order respecting the sin-offering. The great attention that was to be shown to wash the clothes that were sprinkled, in offering the sacrifice, meant no doubt to signify the necessity of divine washing by the blood of JESUS, and the waters of regeneration. Titus 3:5-6. And in the appointment of all the males among the priests partaking of the sacrifice, is it not meant to show the privilege of the faithful in the common sacrifice of CHRIST? Hebrews 13:10.
Leviticus 6:24-30
24 And the LORD spake unto Moses, saying,
25 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 the LORD: it is most holy.
26 The priest that offereth it for sin shall eat it: in the holy place shall it be eaten, in the court of the tabernacle of the congregation.
27 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 the holy place.
28 But the earthen vessel wherein it is sodden shall be broken: and if it be sodden in a brasen pot, it shall be both scoured, and rinsed in water.
29 All the males among the priests shall eat thereof: it is most holy.
30 And no sin offering, whereof any of the blood is brought into the tabernacle of the congregation to reconcile withal in the holy place, shall be eaten: it shall be burnt in the fire.
