Leviticus 11:34-36

Complete Jewish Bible

³⁴ Any food permitted to be eaten that water from such a vessel gets on will become unclean, and any permitted liquid in such a vessel will become unclean. ³⁵ Everything on which any carcass-part of theirs falls will become unclean, whether oven or stove; it is to be broken in pieces — they are unclean and will be unclean for you; ³⁶ although a spring or cistern for collecting water remains clean. But anyone who touches one of their carcasses will become unclean.
