Leviticus 6:24-27

24And the LORD spoke to Moses, saying, 25Speak to 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. 27Whatever shall touch the flesh of it shall be holy: and when there is sprinkled of its blood upon any garment, thou shalt wash that on which it was sprinkled in the holy place.
