'Clean' in the Bible

For you say, 'My doctrine is pure. I am clean in your eyes.'

Who can bring a clean thing out of an unclean? Not one.

What is man, that he should be clean? What is he who is born of a woman, that he should be righteous?

Behold, he puts no trust in his holy ones. Yes, the heavens are not clean in his sight;

Yet shall the righteous hold on his way. He who has clean hands shall grow stronger and stronger.

How then can man be just with God? Or how can he who is born of a woman be clean?

'I am clean, without disobedience. I am innocent, neither is there iniquity in me.
