Redaction: The time of preparation is four years. While the time for preparation of the Nephites is not given explicitly, it may be calculated. It was four years. (See the commentary following Mormon 6:5). This correspondence in the amount of time given for the preparation of a final battle at the hill Ramah/Cumorah must be more than a coincidence, and once again may be laid at the feet of Moroni’s structuring of the events of the Jaredite destruction to parallel those of the Nephites.
