Lev 7.21 Moreover the soul that shall touch any unclean thing, as the uncleanness of man, or any unclean beast, or any abominable unclean thing, and eat of the flesh of the sacrifice of peace offerings, which pertain unto the LORD, even that soul shall be cut off from his people.
Lev 15.5 And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
