Narrative analysis: Nephi's response to his brothers is a marvel of condemning logic. Nephi knows that for all of their complaints against himself and their father, that Laman and Lemuel are in the very least cultural children of Abraham and Moses. He uses their assumptions of the way their world is constructed to place them in a position where they must see themselves as similar to the children of Moses who complained at times against him. By so placing them, Nephi also highlights to them the futility of their position in denying the power of God. It is a very calculated speech.
Nephi sets up his discourse with a rhetorical question. He asks if they believe that the children of Moses could be led from Egypt had they not headed the counsel of the Lord. Nephi is setting up his brothers by requiring from them an admission they cannot withhold. Of course they believe that the children of Israel were led from Egypt by the hand of God. Of course it required their God to lead them. To believe anything else would be to deny their conception of who they were in history. While Laman and Lemuel might deny Lehi and Nephi, they could not deny Moses.
By choosing this particular example, Nephi sets in motion an argument that is first undeniable, and secondly parallel to their own, and hence directly aimed at Laman and Lemuel.
