Webster(i)
11 Then set it empty upon its coals, that the brass of it may be hot, and may burn, and that the filthiness of it may be melted in it, that the scum of it may be consumed.
12 She hath wearied herself with lies, and her great scum went not forth out of her: her scum shall be in the fire.
13 In thy filthiness is lewdness: because I have purged thee, and thou wast not purged, thou shalt not be purged from thy filthiness any more, till I have caused my fury to rest upon thee.
