Matthew Poole and continuators on John 5:37

37 And the Father himself which hath sent me, hath born witness of me ; Ye have neither heard his voice at any time, nor seen his shape .

Not onely in my Baptism, and at my Transfiguration by an audible Voice from Heaven, but by the Voice of his Prophets, by whom he spoke to your Fathers.

You have no knowledge of kim, nor any acquaintance with him. It is expounded, v. 38. Ye have not his word abiding in you: For tho indeed God appeared to the Iews in no shape or similitude; yet they (that is, their Fore-fathers) had heard his Voice, Deut. 4.12. speaking out of the midst of the fire, v. 33. God being an incorporeal Being, hath no such organs of Speech as we have, by which we declare our minds unto others; but God had formed an audible Voice, by which he revealed his will unto the Iews: So as it could onely be said of the Iews of that Generation and their Forefathers, from the time of giving the Law, that they had not heard his Voice; for Exod. 20.19. they then desired that Moses might speak to them, and that God would speak no more immediately. Accordingly, he did by the Prophets speak to them, Heb. 1.3. but they would not believe them; no, not when he spake to them by his Son, who knew his will.
