Proverbs 25:4

Take away the dross from the silver
By putting it into the furnace, and purging it from it: and there shall come forth a vessel for the finer;
not out of the furnace, a vessel formed and shaped, but pure silver shall come out of it for the refiner; of which a vessel may be made, very honourable, beautiful, and fit for use: the application of it is in ( Proverbs 25:5 ) .
