Ezekiel 22:18-20 NIV

[18] “Son of man, the people of Israel have become dross to me; all of them are the copper, tin, iron and lead left inside a furnace. They are but the dross of silver. [19] Therefore this is what the Sovereign LORD says: ‘Because you have all become dross, I will gather you into Jerusalem. [20] As silver, copper, iron, lead and tin are gathered into a furnace to be melted with a fiery blast, so will I gather you in my anger and my wrath and put you inside the city and melt you.
