Lamanites, Amalekites and Amulonites

1. Alma 21: 2-3
     2 Now the Lamanites and the Amalekites and the people of Amulon had built a great city, which was called Jerusalem.
     3 Now the Lamanites of themselves were sufficiently hardened, but the Amalekites and the Amulonites were still harder; therefore they did cause the Lamanites that they should harden their hearts, that they should wax strong in wickedness and their abominations.
2. Alma 23: 14
     14 And the Amalekites were not converted, save only one; neither were any of the Amulonites; but they did harden their hearts, and also the hearts of the Lamanites in that part of the land wheresoever they dwelt, yea, and all their villages and all their cities.
3. Alma 24: 1, 28-29
     1 And it came to pass that the Amalekites and the Amulonites and the Lamanites who were in the land of Amulon, and also in the land of Helam, and who were in the land of Jerusalem, and in fine, in all the land round about, who had not been converted and had not taken upon them the name of Anti-Nephi-Lehi, were stirred up by the Amalekites and by the Amulonites to anger against their brethren.

     28 Now the greatest number of those of the Lamanites who slew so many of their brethren were Amalekites and Amulonites, the greatest number of whom were after the order of the Nehors.
     29 Now, among those who joined the people of the Lord, there were none who were Amalekites or Amulonites, or who were of the order of Nehor, but they were actual descendants of Laman and Lemuel.
