Ezekiel 22:18-20

18“Son of man, the people of Israel have become worthless to me. All of them are like copper, tin, iron, and lead in a smelting furnace. They are like the impurities left from silver.

19This is what the Almighty Lord says: All of you have become worthless. That is why I’m going to gather you in Jerusalem.

20People gather silver, copper, iron, lead, and tin together in a smelting furnace to melt them with a fiery blast. In the same way, in my anger and fury I will gather you and put you in the city. I will melt you there.
