Leviticus 11:32-36

32Also anything on which one of them falls after dying becomes unclean, whether it is an article of wood or clothing, or a skin, or a sack—any article that is used—it must be put in water, and will be unclean until the evening; then it becomes clean.

33As for any earthenware container into which any of these [crawling things] falls, whatever is in it becomes unclean, and you shall break the container.

34Any of the food which may be eaten, but on which [unclean] water falls, shall become unclean, and any liquid that may be drunk in every container shall become unclean.

35Everything that part of their carcass falls on becomes unclean; an oven, or a small stove shall be smashed; they are unclean, and shall be unclean to you.

36Nevertheless a spring or a cistern (reservoir) collecting water shall be clean; but whoever touches one of these carcasses shall be unclean.
