'Clean' in the Bible

For you say, 'My teaching [is] pure, and I am clean in your sight.'

"Who can bring a clean [thing] from an unclean [thing]? No one!

"What [is] a human being, that he can be clean, or that [one] born of a woman can be righteous?

Look, he does not trust his holy ones, and [the] heavens are not clean in his eyes.

But [the] righteous holds on to his way, and {he who has clean hands} increases in strength.

'I [am] clean, without transgression; I [am] pure, and [there is] no guilt in me.
