Ether 9:12–13

And there began to be a war between the sons of Akish and Akish, which lasted for the space of many years, yea, unto the destruction of nearly all the people of the kingdom, yea, even all, save it were thirty souls, and they who fled with the house of Omer. Wherefore, Omer was restored again to the land of his inheritance.
