And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean; and ye shall break it.

And every thing whereupon any part of their carcass 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.
