Behold I say unto you that my servant hath desired  A witness that my Servant Joseph hath got the things w hich he hath testified that he hath got and now Behold thu s shall ye say unto him I the Lord am God I have given these  things unto him & I have commanded him that he should  stand as A witness of these things nevertheless I have  caused him that he should enter into A covenant with  me that he should not show them except I Command him  & he hath no power over them e[x]cept I grant it unto him &  he hath A gift to translate the Book & I have commanded  him that he should shall pretend to no other gift for I will  grant unto him no other gift and verily I say unto you  that woe shall come unto the Inhabitents of the Earth  if they will not hearken unto my words for Behold if  they will not believe my words they would not believe  my servants if it were possible he could show them  all things O ye unbelieving ye stiffnecked Generation Beho ld I have reserved the things which have been spoken of  which I have entrusted to my servant for A wise per pose in me & it shall be made Known unto future  Generations but for this Generation they shall have  my word yea & the testimony of three of my Servan ts shall go forth with my word unto this Generation  yea three shall Know of A surety that those things are  true for I will give them power that they may Behold  & vew these things as they are & to none else will I gran t this power among this Generation & the testimony  of three Witnesses will I send forth & my word & be hold whosoever beleaveth in my word him will I visit  with the manifestations of my spirit & they shall be Born  of me & their testimony shall also go forth & thus  if the People of this Generation harden not their  hearts I will work a reformation among them & I will  put down all lieings & deceivings & Priest Craft &  envyings & strifes & Idolatries and sorceries & all ma ner of Iniquities & I will establish my Church yea  even the church which was taught by my Des iples & now if this Generation do hardon their hea rts [p. 1]
In June 1828, after JS and Martin Harris had completed 116 pages of the Book of Mormon translation, Harris convinced JS to allow him to take the manuscript to Palmyra, New York, to show to relatives. The manuscript was subsequently lost. Harris had borrowed the transcribed pages at least in part to demonstrate to his skeptical wife that he was involved in something meaningful and tangible. This revelation, dated March 1829, was directed to JS and Harris, with the opening line suggesting that Harris sought verification that JS had possession of certain “things” related to the Book of Mormon translation. Though not initially specified, a later revision, appearing in the 1835 Doctrine and Covenants, substituted “plates” for “things.”
The revelation went beyond Harris’s original intent in going to the Lord and promised that the Book of Mormon plates would be shown to three individuals, including Harris. The Book of Mormon was first published in 1830, and it included the testimony of Oliver Cowdery, David Whitmer, and Harris, confirming they had been shown the plates as promised.
Oliver Cowdery may have penned this text soon after he arrived in Harmony, Pennsylvania, early in April 1829. It was printed in the 1833 Book of Commandments.
