Question: Did Joseph Smith attempt to "cover up" Oliver Cowdery's work with a divining rod by changing the wording of the revelation that became Doctrine and Covenants 8:6–8?

The edits to this portion of the revelation were actually performed by Sidney Rigdon, likely with Joseph's approval

A revelation received by Joseph praised Oliver Cowdery's gift of using divining talents. The revelation was published in the Book of Commandments in its original form, then subsequently modified in the Doctrine and Covenants. We do not know why Sidney Rigdon chose to alter the wording of the revelation, but he is the one that actually changed the wording to "rod of nature."

We know based upon the text of the revelation that Oliver possessed a gift of working with something alternately referred to as a "sprout," "thing of nature," or "rod of nature." We also know that the Lord approved of Oliver's use of this gift. The reference was later changed to the "gift of Aaron," but we can only speculate as to the exact reason why. According to the Church History website, the "rod" referred to by Sidney Rigdon when he edited the revelation was likely a divining rod. It is possible that "gift of Aaron" was substituted as the revelatory device because if carried fewer negative connotations than "divining rod." However, a "cover up" is not usually done by committee, and it is clear that multiple individuals assisted in editing the revelations before they were to be published in the Doctrine and Covenants. It is also difficult to claim a "cover up" since "rod of nature" was to be published in the Book of Commandments in 1833, only two years before change to "gift of Aaron" was published in the 1835 Doctrine and Covenants.

We do know that Oliver's gift had to do with receiving revelation, and that Oliver attempted to employ it during the period in which the Book of Mormon was being translated. We also know that Oliver's experience in attempting to translate produced one of the lasting lessons which continues to be taught in Church even today—the knowledge that one must study things out in their mind in order to know the truth of something.
