'Cleansed' in the Bible

And according to the Law, one may almost say, all things are cleansed with blood, and without shedding of blood there is no forgiveness.

Therefore it was necessary for the copies of the things in the heavens to be cleansed with these, but the heavenly things themselves with better sacrifices than these.

Otherwise, would they not have ceased to be offered, because the worshipers, having once been cleansed, would no longer have had consciousness of sins?
