In 1999, the Zarahemla Research Foundation (RLDS) finished an exhaustive review of all known manuscripts and editions of the Book of Mormon in order to restore the text "to its purity." The result was the Restored Covenant Edition of the Book of Mormon. One of their "restorations" involves the proper name "Pahoran" (Helaman 1:2), which they have changed to read "Pahoron." [Zarahemla Research Foundation, "Selected Concordance" in The Book of Mormon: Restored Covenant Edition, p. 940]
Note* This must be considered tentative subject to the verification of Royal Skousen, director of the Book of Mormon manuscript project, who will not comment at this time relative to such changes. [Personal communication, 11/22/1999]
