Ezekiel 22:18-20

18“Son of man, the house of Israel has become dross to Me; they are all bronze, tin, iron, and lead, in the midst of a furnace; they have become dross from silver.

19Therefore thus says the Lord God: ‘Because you have all become dross, therefore behold, I will gather you into the midst of Jerusalem.

20As men gather silver, bronze, iron, lead, and tin into the midst of a furnace, to blow fire on it, to melt it; so I will gather you in My anger and in My fury, and I will leave you there and melt you.
