When the sons of King Mosiah, together with the companions they had chosen to accompany them, arrived at the borders of the Land of Nephi where the main body of the Lamanites dwelt, Aaron, the eldest of the sons, went to a land which the Lamanites called Jerusalem after the place in Judea from which their fathers had come.
The Land of Jerusalem to which Aaron now journeyed was not far from the Waters of Mormon where Alma, the elder, about sixty years previously, gathered with a faithful few to worship the Lord unhindered by King Noah and his wicked priests. It was probably north and a little east of the City of Lehi-Nephi. Here, the Lamanites, Amulonites, Amalekites, and various Nephite apostates, had built a large and thriving city. (About 100 B.C.) The wickedness and abandonment of its people quickly reached their maximum; a little later, both the city and all its inhabitants were engulfed in the bowels of the earth in the dire calamities that attended the Crucifixion of our Lord. Waters came up in the place of this proud city, and a stagnant sea, akin to that which hides Sodom and Gomorrah, occupied the place where its grand palaces and rich synagogues had previously stood.
