The Book Of Mormon

Now when Ammon and his brethren separated themselves in the borders of the land of the Lamanites, behold Aaron took his journey towards the land which was called by the Lamanites, Jerusalem, calling it after the land of their fathers' nativity; and it was away joining the borders of Mormon.

Now the Lamanites and the Amalekites and the people of Amulon had built a great city, which was called Jerusalem.
