Martin Harris reaffirms his testimony as a BoM witness; says an angel showed him the plates.
Martin Harris, Letter to H. B. Emerson, November 23, 1870, rep. Saints' Herald 22, no. 20 (October 15, 1875): 630
Smithfield, Utah, Nov. 23, 1870
Mr. Emerson, Sir:—I received your favor. In reply I will say concerning the plates, I do say that the angel did show to me the plates containing the Book of Mormon. Further, the translation that I carried to Prof. Anthon was copied from these same plates; also, that the Professor did testify to it being a correct translation. I do firmly believe and do know that Joseph Smith was a prophet of God; for without I know he could not had that gift; neither could he have translated the same. I can give if you require it one hundred witnesses to the proof of the Book of Mormon. I defy any man to show me any passage of Scripture that I am not posted on or familiar with. I will answer any question you feel like asking to the best of my knowledge, if you can rely on my testimony of the same. In conclusion, I can say that I arrived in Utah safe, in good health and spirits, considering the long journey. I am quite well at present and have been, generally speaking, since I arrived.
With many respects I remain your humble friend,
MARTIN HARRIS
