“Several experiences in the Book of Mormon indicate that the law of primogeniture (where the first-born son has special rights and privileges) was part of the belief and tradition of Lehi and his colony. Note particularly the following references in this regard: 1 Nephi 18:10; 2 Nephi 5:3; Mosiah 10:11–15” (Ludlow, Companion to Your Study of the Book of Mormon, 116).
