Although his name is not mentioned in the Book of Mormon, in modern times his name was revealed as, Mahonri Moriancumr (lds.org). He was a large and mighty man, a great prophet and highly favored of the Lord. He and his brother led a colony of people from the Tower of Babel to a promised land in the western hemisphere and founded the Jaredite nation. He was a man of such faith that he spoke to the Lord face to face.
