13 And it came to pass that the Nephites began the foundation of a city, and they called the name of the city ^aMoroni; and it was by the east sea; and it was on the south by the line of the possessions of the Lamanites.

  22 Behold, it came to pass that while ^aMoroni was thus breaking down the wars and contentions among his own people, and subjecting them to peace and civilization, and making regulations to prepare for war against the Lamanites, behold, the Lamanites had come into the land of Moroni, which was in the borders by the seashore.

  9 And the city of ^aMoroni did ^bsink into the depths of the sea, and the inhabitants thereof were drowned.
