Jeremiah 6:29

The bellows blow fiercely ; the lead is consumed by the fire ; in vain the refining goes on , for the wicked are not removed .

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

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