The division of the people at this time is as follows, the families of Nephi, Sam, Zoram, Jacob and Joseph go with Nephi. The families of Laman, Lemuel, and Ishmael’s sons become the Lamanites. That the Ishmaelites became Lamanites is shown in Alma, the Lord God set a mark upon them, yea, upon Laman and Lemuel, and also the sons of Ishmael, and Ishmaelitish women (Alma 3:7) Nephi takes anyone who will follow the Lord—the division is not only along family lines but was divided based on allegiance to the Lord (see also Mosiah 25:22-3).
