"Wisdom is too exalted for a fool, he does not open his mouth in the gate"
Wisdom carries clearly the ability to see options and nuances of actions that others do not see: The ability to find the wise course of action amongst the ones presented; the ability to see a good choice amongst the two that are the only choices; to be able to perceive more than the obvious choices is the wise thing. Wisdom is, at times, realizing that the truly wise and righteous choice will not present itself until you are further down the road than you are now or not until you make certain critical – albeit small – choices at the present time.
It could be called: Finding the everybody-wins choice. Waiting for the everybody-wins choice. Bringing about the everybody-wins choice.
The fool cannot apply knowledge. Even if the right information is in front of them, they consistently do what feels right to themselves or is an impulsive choice or is in some way an independent or rebel choice. The fool does not have the ability to discern these subtle choices that will give them the wonderful choice. The fool is impulsive and wants the perfect choice extremely quickly and very obvious. They are also selfish so they have a hard time going away from what they want to eventually get more than they could have dreamed of. They are also rebellious, so they completely do not understand submission and teamwork as a means to personal blessing.
Sometimes you cannot find the wise choice because you are biased toward or against a particular choice. Other times it is because your experience is limited in a certain direction and you cannot see an option that someone else can see.
he does not open his mouth in the gate
The gates of Ancient Israel were where the elders and city officials sat to conduct the business of the city. These were the smartest, wealthiest, and wisest men in the town. They conducted business out in the open for all to see. Therefore, the gates of the city were really City Hall. The Proverb says that the selfish, impulsive, rebellious person – the fool – does not completely understand the things that are being discussed at the City Hall, and they may not even want to be noticed at City Hall.
