'Be Clean' in the Bible

“In your filthiness are lewdness and outrage.Therefore I would have cleansed you,Yet you were not [willing to be] cleansed,You will not be cleansed from your filthiness againUntil I have satisfied My wrath against you.

Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your uncleanness and from all your idols.

‘On the second day you shall offer a male goat without blemish for a sin offering, and they shall cleanse the altar as they cleansed it with the bull.
