Ezekiel 22:18-20

18“Son of man, the house of Israel has become merely dross to me. All of them are copper, tin, iron, and lead inside the furnace; they are just dross from silver.

19Therefore, this is what the Lord God says: Because all of you have become dross, I am about to gather you into Jerusalem.

20Just as one gathers silver, copper, iron, lead, and tin into the furnace to blow fire on them and melt them, so I will gather you in my anger and wrath, put you inside, and melt you.
