Welch has explained how this is directly relevant to the Book of Mormon. “One portion of the Nephite record was sealed; the other part was open,” he wrote. “Consistent with the ancient practices and requirements” and “for security and preservation, the plates were buried; they were both sealed and sealed up.”5 In other words, part of the Book of Mormon plates were physically sealed, and the entire set of plates were sealed up, that is, hidden in the earth for preservation, following ancient practice.
