Alma 62:11

And thus ended the thirtieth year of the reign of the Judges over the people of Nephi: Moroni and Pahoran having restored peace to the land of Zarahemla, among their own people, having inflicted death upon all those who were not true to the cause of freedom.

This ended the thirtieth year of the judges over the people of Nephi. Moroni and Pahoran had brought peace back to the land of Zarahemla among their own people. They had killed all those who were not true to the cause of freedom.

And so the thirtieth year of the judges’ reign over the Nephites came to an end. Moroni and Pahoran had restored peace to Zarahemla by putting to death all who had betrayed the cause of freedom.
