Leviticus 6:24-27

24And the Lord spake unto Moses, saying, 25Speak 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. 26The 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. 27Whatsoever 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.
