Leviticus 6:24-27

24And Jehovah 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 Jehovah: it is most holy. 26The 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. 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 a holy place.
