The Book of Mormon teaches of the dangers of wicked kings, declaring behold, how much iniquity doth one wicked king cause to be committed, yea, and what great destruction (Mosiah 29:17). Yet the righteous reign of Emer clearly shows the great benefit of a righteous king, for in the relatively short span of 62 years, the people had become both exceedingly strong and exceedingly rich. Hereby, we behold how much good doth one righteous king cause to come to pass, yea and what great prosperity!
