1 Chronicles 1:10-12

10 And it came to pass that the war began to be among them in the borders of Zarahemla, by the waters of Sidon.

11 And it came to pass that the Nephites had gathered together a great number of men, even to exceed the number of thirty thousand. And it came to pass that they did have in this same year a number of battles, in which the Nephites did beat the Lamanites and did slay many of them.

12 And it came to pass that the Lamanites withdrew their design, and there was peace settled in the land; and peace did remain for the space of about four years, that there was no bloodshed.
