And every thing whereupon any part of their carcase falleth shall be unclean; whether it be oven, or ranges for pots, they shall be broken down: for they are unclean, and shall be unclean unto you.

Anything upon which one of their carcasses falls will be unclean. If it is an oven or cooking pot, it must be smashed; it is unclean and will remain unclean for you.
