Leviticus 11:33-35

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

Of all meat which may be eaten, that on which such water cometh shall be unclean: and all drink that may be drunk in every such vessel shall be unclean.

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.
