27 ‘I have made you a tester of metalsand my people the ore,that you may observeand test their ways.
28 They are all hardened rebels,going about to slander.They are bronze and iron;they all act corruptly.
29 The bellows blow fiercelyto burn away the lead with fire,but the refining goes on in vain;the wicked are not purged out.
30 They are called rejected silver,because the Lord has rejected them.’
