'Clean' in the Bible

Who, being the outshining of his glory, the true image of his substance, supporting all things by the word of his power, having given himself as an offering making clean from sins, took his seat at the right hand of God in heaven;

And this is an image of the present time; when the offerings which are given are not able to make the heart of the worshipper completely clean,

For they [the gifts, sacrifices, and ceremonies] deal only with [clean and unclean] food and drink and various ritual washings, [mere] external regulations for the body imposed [to help the worshipers] until the time of reformation [that is, the time of the new order when Christ will establish the reality of what these things foreshadow—a better covenant].

For if the blood of goats and oxen, and the dust from the burning of a young cow, being put on the unclean, make the flesh clean:

How much more will the blood of Christ, who, being without sin, made an offering of himself to God through the Holy Spirit, make your hearts clean from dead works to be servants of the living God?

And by the law almost all things are made clean with blood, and without 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.

For the law, being only a poor copy of the future good things, and not the true image of those things, is never able to make the people who come to the altar every year with the same offerings completely clean.

For if this had been possible, would there not have been an end of those offerings, because the worshippers would have been made completely clean and would have been no longer conscious of sins?

let us draw near with a true heart in full assurance of faith, our hearts sprinkled clean from an evil conscience and our bodies washed in pure water.

But will not the man by whom the Son of God has been crushed under foot, and the blood of the agreement with which he was washed clean has been taken as an unholy thing, and who has had no respect for the Spirit of grace, be judged bad enough for a very much worse punishment?
