Textual: This introduction is part of the 1830 edition (with the exception of the text in brackets. It is interesting that the source for this information is declared. Mormon indicates that it comes form the record of Alma. Certainly the current chapter does, but there will be another such preface before our chapter 21, and the source material is not cited there. It is probable that the account will still come from Alma, as it continues the information on the sons of Mosiah who reported their activities to Alma. Neither this section, nor the one beginning with chapter 21 are written in the first person, so we may suppose that this is Alma's recording of the stories as they were told to him.
