Leviticus

And for these ye shall be unclean: whosoever toucheth the carcase of them shall be unclean until the even.

And whosoever beareth ought of the carcase of them shall wash his clothes, and be unclean until the even.

And if any beast, of which ye may eat, die; he that toucheth the carcase thereof shall be unclean until the even.

And he that eateth of the carcase of it shall wash his clothes, and be unclean until the even: he also that beareth the carcase of it shall wash his clothes, and be unclean until the even.

And the priest shall look on him again the seventh day: and, behold, if the plague be somewhat dark, and the plague spread not in the skin, the priest shall pronounce him clean: it is but a scab: and he shall wash his clothes, and be clean.
