The bellows blow,blasting the lead with fire.The refining is completely in vain;the evil ones are not separated out.

Therefore, thus said Jehovah of Hosts: Lo, I am refining them, and have tried them, For how do I do because of the daughter of My people?

And some of the teachers do stumble for refining by them, and for purifying, and for making white -- till the end of the time, for it is yet for a time appointed.

And I have brought the third into fire, And refined them like a refining of silver, And have tried them like a trying of gold, It doth call in My name, and I answer it, I have said, 'My people it is,' And it saith, 'Jehovah is my God!'
