Leviticus 11:27-31

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.

These also shall be unclean unto you among the creeping things that creep upon the earth; the weasel, and the mouse, and the tortoise after his kind,

And the ferret, and the chameleon, and the lizard, and the snail, and the mole.

These are unclean to you among all that creep: whosoever doth touch them, when they be dead, shall be unclean until the even.
