And it came to pass that my father, Lehi, also found upon the plates of brass a genealogy of his fathers; wherefore he knew that he was a descendant of Joseph; yea, even that Joseph who was the son of Jacob, who was sold into Egypt, and who was preserved by the hand of the Lord, that he might preserve his father, Jacob, and all his household from perishing with famine. And they were also led out of captivity and out of the land of Egypt, by that same God who had preserved them. And thus my father, Lehi, did discover the genealogy of his fathers.
