'Purified' in the Bible

Indeed according to the law almost everything was purified with blood, and without the shedding of blood there is no forgiveness.

So it was necessary for the sketches of the things in heaven to be purified with these sacrifices, but the heavenly things themselves required better sacrifices than these.

For otherwise would they not have ceased to be offered, since the worshipers would have been purified once for all and so have no further consciousness of sin?
