This verse leaves the impression that Lehi had been commanded of the Lord to see that his sons were properly married. The antecedent of Nephi’s expression that he had been “blessed of the Lord exceedingly” seems to have been his marriage.
If this is the case, it is a touching tribute to his wife, who, according to Hebrew tradition, remains unnamed. (The Book of Mormon, like the Bible, is in the Hebrew tradition a patriarchal narrative.)
This seems especially likely when it is remembered that Nephi was writing thirty years after his marriage.
