29 The fiery bellows of judgment burn fiercely. But there is too much dross to be removed. The process of refining them has proved useless. The wicked have not been purged.

Darby

29 The bellows are burned^D5214, the lead is consumed by the fire^D5215; they have melted, and melted in vain; and the bad are not plucked away.

Darby Bible Notes

burned - * i.e. so that the current of air, needed to cause the lead to carry off the dross, ceased, leaving unrefined (reprobate) silver. It might read 'the bellows puff.' fire - Others, 'out of their fire [cometh] lead.'

KJV

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