Jeremiah 6:30 DBY

²⁸  They are all the most rebellious of rebels, going about with slander: they are bronze and iron; they are all corrupters.

²⁹  The bellows are burned, the lead is consumed by the fire; they have melted, and melted in vain; and the bad are not plucked away.

³⁰  Reprobate silver shall they call them, for Jehovah hath rejected them.
