Leviticus 11:38-40

³⁸But if any water be put upon the seed, and any part of their carcase fall thereon, it shall be unclean unto you.

³⁹And if any beast, of which ye may eat, die; he that toucheth the carcase thereof shall be unclean until the even.

⁴⁰And 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.
