Leviticus 11:24-28

24And for these ye shall be unclean: whosoever toucheth the carcase of them shall be unclean until the even.

25And whosoever beareth ought of the carcase of them shall wash his clothes, and be unclean until the even.

26The carcases of every beast which divideth the hoof, and is not clovenfooted, nor cheweth the cud, are unclean unto you: every one that toucheth them shall be unclean.

27And whatsoever goeth upon his paws, among all manner of beasts that go on all four, those are unclean unto you: whoso toucheth their carcase shall be unclean until the even.

28And he that beareth the carcase of them shall wash his clothes, and be unclean until the even: they are unclean unto you.
