Leviticus 6:27

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.

Whatsoever shall touch the flesh thereof shall be holy. It was unlawful for any one to touch the flesh of the sin offering except only the consecrated priest; and if the garment of any one was accidentally stained with the spurting of the blood, the spot had to be washed out within the precincts of the holy place. The obvious meaning of the statement is, that the flesh was so holy, only the hand of a consecrated priest might touch it, and the blood was so holy that a drop of it was not allowed to be borne without the sanctuary (Bahr). The flesh on all occasions was boiled or sodden, with the exception of the paschal lamb, which was roasted; and if an earthen vessel had been used, it being porous, and likely to imbibe some of the liquid particles, it was to be broken; if a metallic pan had been used, it was to be scoured and washed with the greatest care, not because the vessels had been defiled, but the reverse-because the flesh of the sin offering having been boiled in them, those vessels were now too sacred for ordinary use.
