Leviticus 11:29-38

“Of the small animals that scurry along the ground, these are unclean for you: the mole rat, the rat, large lizards of all kinds, the gecko, the monitor lizard, the common lizard, the sand lizard, and the chameleon. All 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. If 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. “If such an animal falls into a clay pot, everything in the pot will be defiled, and the pot must be smashed. If 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. Any 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. “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. If the carcass falls on seed grain to be planted in the field, the seed will still be considered clean. But if the seed is wet when the carcass falls on it, the seed will be defiled.
