³⁸but if water have been put on the seed, and any part of their carcase fall thereon, it shall be unclean unto you.

³⁹And if any beast which is to you for food die, he that toucheth the carcase thereof shall be unclean until the even.

⁴⁰And he that eateth of its carcase shall wash his garments, and be unclean until the even: he also that carrieth its carcase shall wash his garments, and be unclean until the even.
