Remove the dross from the silver, and material ¹  for the silversmith will emerge;

My message is like a fire that purges dross! ¹  It is like a hammer that breaks a rock in pieces! ²  I, the Lord, so affirm it! ³ 

The fiery bellows of judgment burn fiercely. But there is too much dross to be removed. ¹  The process of refining them has proved useless. ²  The wicked have not been purged.
