It sufficeth me to say that we are descendants of Joseph.
In the last chapter, Lehi's family spoke in a certain manner of language. In this chapter,
Nephi says nothing at all.
He's not going to say anything about the plates that he murdered Laban for,
except to say that he and his family are descendants of Joseph.
Nephi is trying to use as few words as possible, since he is writing on metal plates.
It mattereth not to him that he is particular to give a full account of all the things, etc., etc., etc.
So he's not going to write pleasing things; he's going to give commandment unto his seed.
"Wherefore, the things which are pleasing unto the world I do not write ... I shall give commandment unto my seed."
they are not of the world. John 17:14
