¹⁸ “Human, the people of Israel have become useless like scum to me. They are like the copper, tin, iron, and lead left in the furnace when silver is purified. ¹⁹ So this is what the Lord God says: ‘Because you have become useless like scum, I am going to put you together inside Jerusalem. ²⁰ People put silver, copper, iron, lead, and tin together inside a furnace to melt them down in a blazing fire. In the same way I will gather you in my hot anger and put you together in Jerusalem and melt you down.
