Martin Harris is reported to have told Ole A. Jensen that he saw the plates and the angel; voice of God told him that the translation was true.
Ole A. Jensen, "Testimony of Martin Harris," 2, MS 5569, Church History Library
The Prophet and Oliver Cowdery, David Whitmer and myself went into a little grove to pray, to obtain a promise that we should behold it with our own eyes. That we could testify to the world We prayed two or three times, and at length the angel stood befor Oliver and David, and showed them the plates, But, Behold I had gone myself to pray and in my desperation I asked the Prophet to kneel down with me, and pray for me, that I may see the plates. and we did so and immediately the angel stood before me and said 'look' and when I glanced at him I fell, But I stood on my feet and saw the angel turn the golden leaves over, and I said "it is enough, my Lord and my God! Then I heard the voice of God say the book is true, and translated correctly. He then turned himself as though he had no more to say; and we made ready to go.
