'Purer' in the Bible

Shall mortal man be more just than +God? Shall a man be purer than his Maker?

Her Nazarites were purer than snow, whiter than milk; they were more ruddy in body than rubies, their figure was as sapphire.

Thou art of purer eyes than to behold evil, and canst not look on mischief: wherefore lookest thou upon them that deal treacherously, and keepest silence when the wicked swalloweth up a man more righteous than he?
