Wisdom is too high for a fool: he openeth not his mouth in the gate.
– Proverbs 24:7
[C]ommentators differ on whether verse 7 is its own saying, or if it is part of the saying before it or after it. It seems best to take it on its own as a saying, though connections can be made with the saying before and after. The word for wisdom here is the general term comprehending all aspects of wisdom—knowledge, understanding, discernment, etc. Being too high means it is above, or beyond, a fool. Though a fool may seek wisdom, he cannot find it, or even recognize it when it is before him (Proverbs 14:6; 17:24). The previous saying emphasized the necessity of wise counsel in making war, but this saying shows the fool unable to even speak to high matters. The image of the gate refers to the place of judgment in the city. It is where important matters were discussed and decided, as well the place of deciding legal matters. Wisdom requires opening one’s mouth to come to the defense of the oppressed and plead for judgment for them (Proverbs 31:8-9). Though fools are known for prating foolishness (Proverbs 15:2, 28), they have nothing to say when wisdom is needed.
