Alma 30:1 - 30:5
Alma 30:1 Behold, now it came to pass that after the people of Ammon were established in the land of Jershon, yea, and also after the Lamanites were driven out of the land, and their dead were buried by the people of the land—
Things were settling down after the events of the last year or so. The Ammonites were settling in the land of Jershon, the Lamanites had been driven out of the area and their large numbers of dead were buried.
Alma 30:2 Now their dead were not numbered because of the greatness of their numbers; neither were the dead of the Nephites numbered—but it came to pass after they had buried their dead, and also after the days of fasting, and mourning, and prayer, (and it was in the sixteenth year of the reign of the judges over the people of Nephi) there began to be continual peace throughout all the land.
The number of dead among both Nephites and Lamanites were not counted. There numbers were just too much. After a time set aside for mourning, fasting and prayer, the people returned to the business of living. And this all happened during the 16th year of the reign of the judges. There was now peace, at least for a while.
Alma 30:3 Yea, and the people did observe to keep the commandments of the Lord; and they were strict in observing the ordinances of God, according to the law of Moses; for they were taught to keep the law of Moses until it should be fulfilled.
The ordinances of the law of Moses were kept as they were supposed too and the Nephites were looking forward to the time when it would be fulfilled.
Alma 30:4 And thus the people did have no disturbance in all the sixteenth year of the reign of the judges over the people of Nephi.
There was peace during the rest of the year.
Alma 30:5 And it came to pass that in the commencement of the seventeenth year of the reign of the judges, there was continual peace.
As the 17th year began, it was looking peaceful.
