According to the Latter-day Saint faith, the 11 witnesses of the Book of Mormon, including the "Three Witnesses" (Oliver Cowdery, Martin Harris, and David Whitmer), all died of natural causes, with
none of them publicly denying their testimonies about the golden plates even though several eventually left the Church due to disagreements with Joseph Smith and other leadership issues; however, some like Oliver Cowdery and Martin Harris later sought to rejoin the Church before their deaths.
Key points about the witnesses' deaths:
- No public denial:
Despite leaving the Church, none of the witnesses ever publicly denied their testimony about seeing the golden plates.
- Causes of death:
All the witnesses died from natural causes, with details depending on the individual's life circumstances.
- Different paths after leaving:
While some like David Whitmer founded their own church, others like Oliver Cowdery and Martin Harris eventually sought to be rebaptized into the LDS Church before their deaths.
Even on their death beds, they never denied what they saw and witnessed with the Gold Plates and the Book of Mormon. Many of them were persecuted after Joseph Smith was murdered. Yet, they never denied their testimonies.
