Alma 4:5

And it came to pass in the seventh year of the reign of the Judges, there was about three thousand five hundred souls that united themselves to the church of God, and were baptized. And thus ended the seventh year of the reign of the Judges over the people of Nephi; and there was continual peace in all that time.

In the seventh year that judges ruled, about 3,500 people joined the church of God and were baptized. That is how the seventh year ended. There was peace the whole time.

In the seventh year of the judges’ rule, about thirty-five hundred people joined the church and were baptized. That ended the seventh year of the judges over the Nephites, and there was continual peace the whole time.
