Textual: After the transition information in verse one that links this event with the ending of the last chapter, we have the introduction of the passing of the plates from Alma to Helaman. This is a charge that was promised to Helaman during his blessing in the previous year (Alma 37:1-2).
The giving of the plates takes the form of a type of “recommend interview” where Alma reviews the essential faithful understanding of Alma before giving him the plates. The first question deals with the task of the plates, and Helaman’s remembrance and belief in the sacred nature of that mission.
