Leviticus 11:37-41

And if any part of their carcase fall upon any sowing seed which is to be sown, it shall be clean.

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.
