Revelation, April 1829–D [D&C 9]

no thought, save it was to ask me; but behold I say  unto you, that you must study it out in your mind;  then you must ask me if it be right, and if it is right,  I will cause that your bosom shall burn within you:  therefore, you shall feel that it is right; but if it be  not right, you shall have no such feelings, but you  shall have a stupor of thought, that shall cause you  to forget the thing which is wrong: therefore, you  cannot write that which is sacred, save it be given  you from me.
4 Now if you had known this, you could have  translated: nevertheless, it is not expedient that you  should translate now. Behold it was expedient  when you commenced, but you feared and the time  is past, that it is not expedient now: for, do you not  behold that I have given unto my servant Joseph  sufficient strength, whereby it is made up? and nei ther of you have I condemned.
5 Do this thing which I have commanded you,  and you shall prosper. Be faithful, and yield to no  temptation. Stand fast in the work wherewith I  have called you, and a hair of your head shall not  be lost, and you shall be lifted up at the last day:  Amen. [p. 21]
Although Oliver Cowdery had been granted the opportunity to translate a portion of the ancient record, his attempt did not turn out as he hoped. The introductory note to the earliest extant partial text of this revelation states that it was given because Cowdery “was desirous to know the reason why he could not translate.” After words of reassurance and counsel, Cowdery was promised that he would yet assist in the translation of other records.
Copied into Revelation Book 1 by John Whitmer, this revelation was initially dated 1829. Subsequently, Cowdery added “April 1829” to the introductory heading. Though Revelation Book 1 provides the earliest text, it is incomplete due to the loss of several pages from the manuscript book. This text is drawn from the 1833 Book of Commandments, “given to Oliver, in Harmony, Pennsylvania, April, 1829.”
