Leviticus 11:38-40

³⁸soothly if any man sheddeth out the seed with water, and afterward the water is touched with dead bodies by themselves, it shall be defouled anon. (but if anyone poureth out the seed with water, and afterward the seed is touched by their dead bodies, at once it shall be defiled, or unclean.)

³⁹If a beast is dead, which it is leaveful to you to eat, (or If a beast dieth naturally, which it is lawful for you to eat), he that toucheth the dead body thereof shall be unclean till to eventide;

⁴⁰and he that eateth thereof anything, either beareth it, shall wash his clothes, and shall be unclean till to eventide.
