Leviticus 14:42

And they shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house.

They shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house.

and they shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house.

and they have taken other stones, and brought `them' in unto the place of the stones, and other clay he taketh and hath daubed the house.

So different stones must be obtained to replace the contaminated ones, as well as additional mortar to replaster the house.
