Leviticus 6:24

"And Jehovah spake unto Moses, saying, Speak unto Aaron and 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. The priest that offereth it for sin shall eat it: in a holy place shall it be eaten, in the court of the tent of the meeting. 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 a holy place. But the earthen vessel wherein it is boiled shall be broken; and if it be boiled in a brazen vessel, it shall be scoured and rinsed in water. Every male among the priests shall eat thereof: it is most holy. And no sin-offering whereof any of the blood is brought into the tent of meeting to make atonement in the holy place, shall be eaten: it shall be burnt with fire."

These instructions cover about the same ground as Leviticus 4, with the exception of the provision for any blood that goes astray. Since it is the blood that sanctifies, it must not be spilled on objects not commanded to be sprinkled with it; and if it should happen accidentally, it must be washed off if possible; and in cases (as in that of the earthen vessel) where stains could not be removed, the vessel had to be destroyed.

Among the prohibitions here was that forbidding a priest to eat of any sin-offering brought by himself, or for the whole congregation of Israel, as upon the Day of Atonement, etc.
