Proverbs 24:7

Wisdom is too high for a fool For a wicked man, whose sins enfeeble his mind, and make it incapable of wisdom. Or, he judges it too difficult for him to understand: he despairs of attaining it, because he will not put away his sins, and be at the trouble of using the means necessary in order to that end: as, on the contrary, wisdom is said to be easy to him that understandeth, Proverbs 14:6, because he seriously gives his mind to it, and therefore easily and certainly attains it. He openeth not his mouth in the gate He knows not how to speak acceptably in the public assembly.
