Jeremiah 6:28-30

Amplified Bible, Classic Edition

²⁸ They are all the worst [kind] of rebels and utter and total revolters against God, going about publishing slander. They are [not gold and silver ore, but] bronze and iron; they are all corrupters.

²⁹ The bellows blow fiercely, the lead is consumed by the fire; in vain do they continue refining, for the wicked [the dross] are not removed.

³⁰ Men will call them reprobate and rejected silver [only dross, without good metal], because the Lord has rejected them.
