King Solomon lived to be 80 years old. King Solomon is most known  for asking for and receiving the gift of 'wisdom' to rule God's  peoples.
Solomon was prematurely old ( 1Ki_11:4 ), for he was only about 60 at death. However, there is more to this than at first sight. Before King David died in 970BC (Ussher) he told his son Solomon to shew thyself a man (KJV) or be a man (BBE).
