Leviticus 11:23 (KJV)

And the swan, and the pelican, and the gier eagle,

And the stork, the heron after her kind, and the lapwing, and the bat.

All fowls that creep, going upon all four, shall be an abomination unto you.

Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth;

Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.

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.

The 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.

And 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.

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