Leviticus 11:34-40

³⁴And all food that is eaten, on which water shall come from such a vessel, shall be unclean; and every beverage which is drunk in any such vessel, shall be unclean.

³⁵And every thing on which there shall fall of their dead bodies shall be unclean; ovens and stands for jars shall be broken down: these are unclean, and they shall be unclean to you.

³⁶Only if the water be of fountains of water, or a pool, or confluence of water, it shall be clean; but he that touches their carcases shall be unclean.

³⁷And if one of their carcases should fall upon any sowing seed which shall be sown, it shall be clean.

³⁸But if water be poured on any seed, and one of their dead bodies fall upon it, it is unclean to you.

³⁹And if one of the cattle die, which it is lawful for you to eat, he that touches their carcases shall be unclean till evening.

⁴⁰And he that eats of their carcases shall wash his garments, and be unclean till evening; and he that carries any of their carcases shall wash his garments, and bathe himself in water, and be unclean till evening.
