In Alma 30:59 we find that Korihor went forth among "a people who had separated themselves from the Nephites and called themselves Zoramites, being led by a man whose name was Zoram." As the reader will soon find, this separation of the Zoramites was not only geographical (Alma 31:3) and spiritual (Alma 31:8-11), but political as well (Alma 31:4). Therefore, the land of Antionum (where the Zoramites lived) might have been located outside the general land of Zarahemla, although within the control at this time of the Nephites. Going to this land might have symbolically been the farthest that Korihor could distance himself from Alma (or the Lord), and yet he was still run over and trampled by these people who thought themselves better than anyone else.
