pages & then shalt thou stop for a season even untill  I command thee again. then thou mayest translate & excep  thou do this Behold thou shalt have no more gift & I will  take away the things which I have entrusted with thee &  now because I foresee the lieing in wait to destroy  thee yea I foresee that if my Servant humbleth not  himself & receive a witness from my hand that he will  fall into transgression & there are many that lie in wait  to destroy thee off the face of the Earth & for this cause  that thy Days may be prolounged I have given unto you  these Commandments Yea for this Cause have I said  stop & stand still untill I Command thee & I will pro vide means whereby thou mayest Accomplish the  thing I have Commanded thee & if thou art faithful  in Keeping my Commandments ye shall be lifted  up at the last Day [p. 3]
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.
