'Cleansed' in the Bible

In fact, under the Law almost everything is cleansed with blood, and without the shedding of the blood there is no forgiveness.

Thus it was necessary for these earthly copies of the things in heaven to be cleansed by these sacrifices, but the heavenly things themselves are made clean with better sacrifices than these.

Otherwise, would they not have stopped offering them, because the worshipers, cleansed once for all, would no longer be aware of any sins?

For by the one offering He has perfected forever and completely cleansed those who are being sanctified [bringing each believer to spiritual completion and maturity].

let us approach [God] with a true and sincere heart in unqualified assurance of faith, having had our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
