¹⁹ A man can see his face in a mirror.
    But his thoughts show what he is really like.
²⁰ The deep hole of death always wants more dead people to fill it.
    In the same way, a person wants to have everything that he sees.
²¹ You need a hot fire to see if silver and gold are pure.
    In the same way, when people praise you,
    they can see what you are really like.
