Matthew Poole and continuators on Proverbs 24:7

7 Wisdom is too high for a fool , he openeth not his mouth in the gate .

Either 1. really, it is above his reach or capacity. Or 2. in his opinion; he judgeth it too hard for him, he despairs of attaining it, he pretends the impossibility of it, because he will not put himself to the charge or trouble of getting it: as on the contrary Wisdom is said to be easie to him that understandeth, Prov. 14. 6. because he seriously giveth his mind to it, and therefore easily and certainly attains to it.

For a wilful Fool, or a wicked Man, whose lusts enfeeble and darken his Mind, and make it uncapable of Wisdom.

Either 1. he can say nothing for himself when he is accused before the Magistrate, for which he gives frequent occasion. Or 2. he knows not how to speak acceptably, and profitably in the publick Assembly among wise men.
