Ezek 22:18-20

18Mortal, the house of Israel has become dross to me; all of them, silver, bronze, tin, iron, and lead. In the smelter they have become dross.19Therefore thus says the Lord GOD: Because you have all become dross, I will gather you into the midst of Jerusalem.20As one gathers silver, bronze, iron, lead, and tin into a smelter, to blow the fire upon them in order to melt them; so I will gather you in my anger and in my wrath, and I will put you in and melt you.
