The Amalekite convert is the single Amalekite said to have accepted the gospel during the mission of the sons of Mosiah among the Lamanites. When the record lists the Lamanite cities and lands whose people were converted and laid down their weapons, it notes that the Amalekites were not converted “save only one,” and that none of the Amulonites were converted (Alma 23:14).
The Amalekites were Nephite dissenters who had joined the Lamanites, and along with the Amulonites they hardened their own hearts and the hearts of the Lamanites in the lands where they lived (Alma 23:14). Mormon explicitly confirms that among all those who joined the people of the Lord at that time, none were Amalekites, Amulonites, or of the order of Nehor—only actual descendants of Laman and Lemuel (Alma 24:29). He adds the doctrinal observation that those once enlightened who fall into transgression become more hardened than those who never knew, making their state worse (Alma 24:30). The single Amalekite convert thus stands against the sharpest gradient the text describes. The text gives no name, history, or further detail about this one convert beyond the fact of the exception.
