Jeremiah 6:27-30 - Jeremiah Appointed As An Examiner
27 I have made thee a trier and a fortress among my people; that thou mayest know and try their way. 28 They are all grievous revolters, going about with slanders; they are brass and iron: they all of them deal corruptly. 29 The bellows blow fiercely; the lead is consumed of the fire: in vain do they go on refining; for the wicked are not plucked away. 30 Refuse silver shall men them, because Jehovah hath rejected them.
