When Amalickiah invaded and attacked the city of Moroni, the people "fled" and "came to the city of Nephihah" (Alma 51:24). Apparently, the city of Nephihah was more secure. Maybe Moroni's army was closer to Nephihah. Perhaps the city of Nephihah was nearer to the city of Moroni than the city of Moroni was to the city of Lehi. Perhaps the city of Nephihah was somewhat out of the invasion path.
