"The copy made by Joseph C. Kingsbury is a true and correct copy of the original in every respect. The copy was carefully preserved by Bishop Whitney, and but few knew of its existence until the temporary location of the Camps of Israel at Winter Quarters, on the Missouri River, in 1846. * * * * *

"Salt Lake City, Feb. 16th, 1874."
On May 22, 1886, Joseph C. Kingsbury made the following statement before Charles W. Stayner, a notary public, in Salt Lake City:
"In reference to the affidavit of Elder William Clayton, on the subject of the celestial order of patriarchal marriage, published in the Deseret Evening News of May 20th, 1886, and particularly as to the statement made therein concerning myself, as having copied the original revelation written by Brother Clayton at the dictation of the Prophet Joseph, I will say that Bishop Newel K. Whitney, handed me the revelation above referred to either on the day it was written or the day following, and stating what it was, asked me to take a copy of it. I did so, and then read my copy of it to Bishop Whitney, we compared it with the original which he held in his hand while I read to him. When I had finished reading, Bishop Whitney pronounced the copy correct, and Hyrum Smith coming into the room at the time to fetch the original, Bishop Whitney handed it to him. I will also state that this copy, as also the original are identically the same as that published in the present edition [1886] of the Book of Doctrine and Covenants.
"I will add that I also knew that the Prophet Joseph Smith had married other women besides his first wife, Emma; I was well aware of the fact of his having married Sarah Ann Whitney, the eldest daughter of Bishop Newel K. Whitney and Elizabeth Ann Whitney, his wife. And the Prophet Joseph told me personally that he had married other women, in accordance with the revealed will of God, and spoke concerning the principle as being a command of God for holy purposes.

II.
Authorship of the Revelation.
In addition to the testimony of these affidavits as to the authorship of the revelation, and many more on file in the Church Historian's office, equally positive and unimpeachable, which might be quoted, there is another sort of evidence as to the authorship, not before used, so far as I know, to which I desire to appeal, and which is even more certain and convincing on this subject than the testimony of any affidavit by whomsoever given. I refer to the internal evidence that Joseph Smith, under the inspiration of God, of course, is the author of it. The revelation carries with it so many characteristics of his style found in other revelations given through him, that to doubt his authorship of it is impossible. Let us consider these characteristics.
