Matthew Poole and continuators on Lamentations 4:1

1 HOw is the gold become dim! how is the most fine gold changed ! the stones of the sanctuary are poured out in the top of every street .

Though some take Gold here metaphorically as signifying the most precious things, yet the most and best interpreters take it in its native sense, for the Gold which adorned the Temple either in its cieling or in its vessels, the house of the Lord being burnt by Nebuzaradan. Ier. 52.13. the Gold in and about the Temple must needs be discoloured, How! is here a note of admiration.

That is, are tumbled down and scattered in the head of every Street about the City.
