Leviticus 14:40

That they may take away the stones Some have thought the leprosy in the house was typical of the idolatry which did strangely cleave to the Jewish Church, and though some of the reforming kings took away the infected stones, yet still it broke out again, till, by the captivity in Babylon, God took down the house and carried it to an unclean land; and that proved an effectual cure of their inclination to idols, and idolatrous worship. An unclean place Where they used to cast dirt and filthy things.
