Leviticus 11:38-40

³⁸But if water be put upon the seed, and aught of their carcass fall thereon, it is unclean unto you.

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

⁴⁰And he that eateth of the carcass of it shall wash his clothes, and be unclean until the even; he also that beareth the carcass of it shall wash his clothes, and be unclean until the even.
