Upon the arrival of the people of Alma to the land of Zarahemla, king Mosiah caused that the records that had been kept by the people of Zeniff, and also the account of Alma, should be read among all the people of Zarahemla, which at this point in time now consisted of Nephites, Mulekites, and the newly joined people of Limhi and Alma (though they too were also descendants of Nephi).
As I've contemplated the purposes for which king Mosiah would cause to read this history, there are a couple of thoughts that impress me about this. I am reminded also of President Hinckley's emphasis on our own pioneer history. Strategically, here king Mosiah had received a notable influx of new citizens among their own, the natural human tendency, without understanding of where they were coming from and what hardships they had endured, would probably have given way to gossiping and other forms of potentially harmful misunderstandings. To completely eradicate such a tendency, and to create a bond among the existing citizens and these new comers, very wisely king Mosiah decided to publish their history among his own people.
There were other benefits to be had, as well. Perhaps the more notable benefit was the testimony of Abinadi which was found at the heart of this story. The spiritual significance and testimony of the Savior was universally applicable and as beneficial to the people at Zarahemla as it was to Alma and those who followed him.
As mentioned earlier, having heard the account of the people of Zeniff and Alma prepared the people of Zarahemla to completely accept and embrace the these new comers. That there is no account of contention or difficulties among the church at this time is also evident of the wisdom of king Mosiah's proactive decision to make available this account among the people.
It also strikes me as important that having heard this account may have become a converting point of testimony among the people of Zarahemla. While not on the same level as conversion as what the people of Alma had experienced in testing their faith, by any means, it was still a spring board for faith. In this regard, I see the Savior in these verses just as one would in any history of spiritual pioneers.
The presentation of this record among the people caused great reactions of sympathy and joy. (vs. 8 and 9)
What is most interesting however is the revelatory nature of the
experience that caused the children of Amulon to completely forsake
their fathers. This final point is one of profound implication. Because of their wickedness, Amulon and his associates lost their posterity, or suffer a separation from their families. The implication of such were both immediate and eternal.
