1 Nephi 1:1; 2:5; “I, Nephi, having been born of goodly parents…he did travel in the wilderness with his family, which consisted of my mother, Sariah, and my elder brothers, who were Laman, Lemuel, and Sam.”
www.josephsmith.net says this about Joseph; “Born of Goodly Parents… His other siblings, in order of age… Alvin (b. 1798), Hyrum (b. 1800), Sophronia (b. 1803), Samuel Harrison (b. 1808), Ephraim (b. 1810), William (b. 1811), Katherine (b. 1813), Don Carlos (b. 1816), and Lucy (b. 1821).”
Psalm 58:3; “The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies.”
Just another proof the Book of Mormon is about Joseph Smith, not the people of South America.
