As these parallels are seen, it helps illuminate Nephi’s careful and very conscious choice of Isaiah passages. The use of Isaiah 48–49 in 1 Nephi 20–21 does not appear to be random. It is unlikely that these chapters were sloppily inserted as irrelevant filler. They seem to be deliberately selected prophetic passages used by someone who was intimately familiar with their specific relevance to the personal experiences of Lehi’s family.
