Leviticus 11:31-38

31All these small animals are unclean for you. If any of you touch the dead body of such an animal, you will be defiled until evening.

32If such an animal dies and falls on something, that object will be unclean. This is true whether the object is made of wood, cloth, leather, or burlap. Whatever its use, you must dip it in water, and it will remain defiled until evening. After that, it will be ceremonially clean and may be used again.

33“If such an animal falls into a clay pot, everything in the pot will be defiled, and the pot must be smashed.

34If the water from such a container spills on any food, the food will be defiled. And any beverage in such a container will be defiled.

35Any object on which the carcass of such an animal falls will be defiled. If it is an oven or hearth, it must be destroyed, for it is defiled, and you must treat it accordingly.

36“However, if the carcass of such an animal falls into a spring or a cistern, the water will still be clean. But anyone who touches the carcass will be defiled.

37If the carcass falls on seed grain to be planted in the field, the seed will still be considered clean.

38But if the seed is wet when the carcass falls on it, the seed will be defiled.
