Leviticus 11:31–38

³¹These are unclean for you among all that swarm; whoever touches one of them when they are dead shall be unclean until the evening. ³²And anything upon which any of them falls when they are dead shall be unclean, whether an article of wood or cloth or leather or sackcloth, any article that is used for any purpose; it shall be dipped in water, and it shall be unclean until the evening, and then it shall be clean.^{* 33}And if any of them falls into any clay vessel, all that is in it shall be unclean, and you shall break the vessel.^{* 34}Any food that could be eaten shall be unclean if water from any such vessel comes upon it, and any liquid that could be drunk shall be unclean if it was in any such vessel. ³⁵Everything on which any part of the carcass falls shall be unclean; whether an oven or stove, it shall be broken in pieces; they are unclean and shall remain unclean for you. ³⁶But a spring or a cistern holding water shall be clean, while whatever touches the carcass in it shall be unclean. ³⁷If any part of their carcass falls upon any seed set aside for sowing, it is clean, ³⁸but if water is put on the seed and any part of their carcass falls on it, it is unclean for you.
