So the Nephite people had just gone through a peaceful revolution. Now Mormon wants to conclude this great historical epic by telling us that the two great leaders of that generation had now passed away and a new order of things had been established. Concerning Alma the elder, he says:
“And now it came to pass that his father died, being eighty and two years old, having lived to fulfil the commandments of God. And it came to pass that Mosiah died also, in the thirty and third year of his reign, being sixty and three years old; making in the whole, five hundred and nine years from the time Lehi left Jerusalem. And thus ended the reign of the kings over the people of Nephi; and thus ended the days of Alma, who was the founder of their church.”
