Jer.6.29

The bellows are burned, the lead is consumed of the fire; the founder melteth in vain: for the wicked are not plucked away.

Jer.6.29

Refining fires are cranked up to white heat, but the ore stays a lump, unchanged. It's useless to keep trying any longer. Nothing can refine evil out of them.

Jer.6.29

The bellows blow fiercely to burn away the lead with fire, but the refining goes on in vain; the wicked are not purged out.

Jer.6.29

The bellows blow fiercely, The lead is consumed by the fire; The smelter refines in vain, For the wicked are not drawn off.
