'Cleansed' in the Bible

According to the law, nearly everything is cleansed with blood, and apart from shedding of blood there is no remission.

It was necessary therefore that the copies of the things in the heavens should be cleansed with these; but the heavenly things themselves with better sacrifices than these.

Or else wouldn't they have ceased to be offered, because the worshippers, having been once cleansed, would have had no more consciousness of sins?
