Leviticus 11:24-28

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

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

26Every beast which parteth the hoof, and is not clovenfooted, nor cheweth the cud, is unclean unto you: every one that toucheth them shall be unclean.

27And whatsoever goeth upon its paws, among all beasts that go on all four, they 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.
