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.
Jewish Publication Society of America Version (JPS1917) - Leviticus 11:35 >And every thing whereupon any part of their carcass falleth shall be unclean; whether oven, or range for pots, it shall be broken in pieces; they are unclean, and shall be unclean unto you.
