Earlier I noted that the story of the acquisition of the brass plates served as a turning point in the narrative of the events of the Lehite exodus, primarily the shift from the story of Lehi to the story of Nephi. Note how this verse continues the transition. While the initial revelation to leave Jerusalem is clearly Lehi's story (and Nephi treats it as such) at this point in time Nephi equates himself in narration with his father. He notes that "thus fair I and my father had kept the commandments." From a narrative standpoint (probably not from a spiritual or social standpoint - at least not at this time in the story) Nephi is now on equal footing with is father.
