'Pure' in the Bible

'Shall mortal man be more just than God? Shall a man be more pure than his Maker?

If you were pure and upright, surely now he would awaken for you, and make the habitation of your righteousness prosperous.

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

Although there is no violence in my hands, and my prayer is pure.

Behold, even the moon has no brightness, and the stars are not pure in his sight;

The topaz of Ethiopia shall not equal it, Neither shall it be valued with pure gold.
