Leviticus 11:23-28

23But every winged crawling thing that hath four feet shall be an abomination unto you.

24And by these ye shall make yourselves unclean; whoever toucheth their carcase shall be unclean until the even.

25And whoever carrieth [ought] of their carcase shall wash his garments, and be unclean until the even.

26Every beast that hath cloven hoofs, but not feet quite split open, nor cheweth the cud, shall be unclean unto you: every one that toucheth them shall be unclean.

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

28And he that carrieth their carcase shall wash his garments, and be unclean until the even: they shall be unclean unto you.
