Helaman 11:24
And it came to pass that in the *eightieth year of the reign of the judges over the people of Nephi, there were a certain number of the dissenters from the people of Nephi, who had some years before gone over unto the Lamanites, and taken upon themselves the name of Lamanites, and also a certain number who were real descendants of the Lamanites, being stirred up to anger by them, or by those dissenters, therefore they commenced a war with their brethren.
