Nephi suggests that the servant go with them into the wilderness. Now, at last, we learn that the servant is Zoram. Only after the crisis has ended would this information have been exchanged. Now, as Zoram is to become essentially part of the family, it is now relevant.
Why would Zoram go? He probably understood that were he to return to Jerusalem and to a dead master, with the plates of brass missing, that the one who had held the keys would also hold the blame. Although he would not understand the nature of his future with Lehi’s family, it would be preferable to the probable execution he would face in Jerusalem. Once he received the oath that they would treat him as a free man, it is probable that the option to join Lehi’s group was seen as the much better choice.
Nephi also clarifies the reason that they made this offer. They feared that those in Jerusalem might believe Zoram’s story and seriously pursue the brothers. That could have been disastrous for the entire family. Thus, it was beneficial for Zoram, and beneficial to Lehi’s family.
Nephi signals that another episode of the story has ended because they travel “unto the tent of our father.” That literary device continues to mark the bounds of parts of the story. However, even though it is an ending, and even though it ends a modern chapter, Nephi’s story is not finished, and his original chapter continues.
