Jeremiah 6:29

The bellows are burned, in the long process which was intended to purify the people and produce some amount of gold, the lead is consumed of the fire, or, "out of its fire comes lead," instead of the precious metal which the Lord had a right to expect; the founder melteth in vain, there were no such results as one might have expected; for the wicked are not plucked away, the great mass of the people are dross, worthless metal.
