Verse 10
Delight is not seemly for a fool - תענוג taanug, splendid or luxurious living, rank, equipage, etc. These sit ill on a fool, though he be by birth a lord.
For a servant to have rule over princes - I pity the king who delivers himself into the hands of his own ministers. Such a one loses his character, and cannnot be respected by his subjects, or rather their subjects. But it is still worse when a person of mean extraction is raised to the throne, or to any place of power; he is generally cruel and tyrannical.
