I have heard of thee - I have now such a discovery of thee as I have never had before. I have only heard of thee by tradition, or from imperfect information; now the eye of my mind clearly perceives thee, and in seeing thee, I see myself; for the light that discovers thy glory and excellence, discovers my meanness and vileness.
I have heard of thee by the hearing of the ear - Referring to the indistinct views which we have of anything by merely hearing of it, compared with the clear apprehension which is furnished by sight. Job had had such views of God as one may obtain by being told of him; he now had such views as are furnished by the sight. The meaning is, that his views of God before were dark and obscure.
But now mine eye seeth thee - We are not to suppose that Job means to say that he actually “saw” God, but that his apprehensions of him were clear and bright “as if” he did. There is no evidence that God appeared to Job in any visible form. He is said, indeed, to have spoken from the whirlwind, but no visible manifestation of Yahweh is mentioned.
