Terrance Szink notes that as Nephi made tools and was about tho begin building the boat as the Lord had commanded him, his brothers, as was their habit, began to murmur. They were skeptical of Nephi's ability to build a seaworthy craft and of his claim that he had been instructed of the Lord. While the first doubt may have been justifiable, the second demonstrates their spiritual immaturity and poor memories. . . . Nephi responded by recounting the history of the Exodus, touching on many of the ideas he would later use in writing the story of his own wilderness journey. (See the commentary on 1 Nephi 17:26) This recapitulation of the Exodus may have been a memorized recitation that was part of the learning of his father (1 Nephi 1:1) mentioned by Nephi at the start of his record. (See S. Kent Brown, "Approaches to the Pentateuch," Studies in Scripture, Vol. 3: The Old Testament, 2:18.) Perhaps Laman and Lemuel had also learned such recitations as children, for as Nephi talked to them, he at first used the phrases "now ye know," "and ye know," "but ye know," "and ye also know," and "yea, and ye also know" when recounting the basics of the story.
