'Clean' in the Bible

Her priests have done violence to my law, and have profaned my holy things: they have made no distinction between the holy and the common, neither have they caused men to discern between the unclean and the clean, and have hidden their eyes from my Sabbaths, and I am profaned among them.

I will sprinkle clean water on you, and you shall be clean: from all your filthiness, and from all your idols, will I cleanse you.

Then he said to me, Son of man, these bones are the whole house of Israel: behold, they say, Our bones are dried up, and our hope is lost; we are clean cut off.

They shall teach my people the difference between the holy and the common, and cause them to discern between the unclean and the clean.
