'Cleansed' in the Bible

Son of man, say unto her, Thou art a land that is not cleansed, nor rained upon in the day of indignation.

In thy filthiness is lewdness: because I have cleansed thee and thou wast not cleansed, thou shalt not be cleansed from thy filthiness any more, till I have caused my wrath toward thee to rest.

And after he is cleansed, they shall reckon unto him seven days.
