King Benjamin had three sons: Mosiah 2, who became king; Helorum, and Helaman. 1 (Mosiah 1:2.) While a great portion of the first chapter of Mosiah deals with Benjamin's teachings to his sons, Helorum and Helaman 1 are not mentioned again in the Book of Mormon.
King Benjamin instructed his sons in all the learning of the people, both sacred and secular, and in the history of the Nephites. He made particular reference to God's dealings with his people and His preserving care over them.After King Benjamin had finished teaching his sons, he instructed that the people of Zarahemla gather around the temple, where, during a lengthy address, he named Mosiah as his successor to the Nephite throne.
In Commentary on the Book of Mormon, George Reynolds and Janne M. Sjodahl wrote of the circumstances under which Mosiah ascended the throne:
"In the presence of his future subjects, under the shadow of the holy temple, Mosiah was set apart to rule a people whose sins were forgiven through their abiding faith in the as-yet-unborn Redeemer.
"Could a king come to the throne under more auspicious circumstances? Profound peace ruled with all who were outside his dominions, and within its borders reigned union, contentment, prosperity, happiness, and, what is more, righteousness.
"Mosiah was 30 years old when he began to reign. This was 476 years after Lehi left Jerusalem. Mosiah followed in the footsteps of his father and taught his people to be industrious; he also set them a good example by tilling a portion of the earth to maintain himself and his dependents."
Mosiah was the last of the kings of Zarahemla, preceding the judges. He translated the contents of the 24 plates of gold that were delivered to him by King Limhi. (See related article on this page.)
