Leviticus 11:38-42

But if any water be put upon the seed, and any part of their carcase fall thereon, it shall be unclean unto you.

And if any beast, of which ye may eat, die; he that toucheth the carcase thereof shall be unclean until the even.

And he that eateth of the carcase of it shall wash his clothes, and be unclean until the even: he also that beareth the carcase of it shall wash his clothes, and be unclean until the even.

And every creeping thing that creepeth upon the earth shall be an abomination; it shall not be eaten.

Whatsoever goeth upon the belly, and whatsoever goeth upon all four, or whatsoever hath more feet among all creeping things that creep upon the earth, them ye shall not eat; for they are an abomination.
