King Mosiah

Church Educational System
King Benjamin named his son after his father. We might, therefore, refer to King Benjamin’s father as Mosiah I and to King Benjamin’s son as Mosiah II. It was Mosiah I who was commanded by the Lord to take those who would follow him and depart out of the land of Nephi into the wilderness because of the wickedness of the Nephites (see Omni 1:12). The book of Mosiah, however, is named after Mosiah II. He is the one who kept the record.
