Noah, city in the land of Zarahemla, near Ammonihah. Its defenses were strengthened against attack by Moroni. When Lamanites tried to break through the heavily fortified banks of earth surrounding Noah, they were unable to penetrate the city and were slain, filling the ditches with their bodies.
Amalickiah marches toward Noah, Alma 49:12–13
is strengthened by Moroni, Alma 49:14–15
12 Therefore they retreated into the wilderness, and took their camp and marched towards the land of Noah, supposing that to be the next best place for them to come against the Nephites.
13 For they knew not that Moroni had fortified, or had built forts of security, for every city in all the land round about; therefore, they marched forward to the land of Noah with a firm determination; yea, their chief captains came forward and took an oath that they would destroy the people of that city. (Alma 49)
14 But behold, to their astonishment, the city of Noah, which had hitherto been a weak place, had now, by the means of Moroni, become strong, yea, even to exceed the strength of the city Ammonihah.
15 And now, behold, this was wisdom in Moroni; for he had supposed that they would be frightened at the city Ammonihah; and as the city of Noah had hitherto been the weakest part of the land, therefore they would march thither to battle; and thus it was according to his desires. (Alma 49)
