Adam Clarke on Proverbs 22:3

A prudent man foreseeth the evil - God in mercy has denied man the knowledge of futurity; but in its place he has given him hope and prudence. By hope he is continually expecting and anticipating good; by prudence he derives and employs means to secure it. His experience shows him that there are many natural evils in a current state, the course of which he can neither stem nor divert: prudence shows him beforehand the means he may use to step out of their way, and hide himself. The simple - the inexperienced, headstrong, giddy, and foolish - rush on in the career of hope, without prudence to regulate, chastise, and guide it; thus they commit many faults, make many miscarriages, and suffer often in consequence; and the commission of crimes leads to punishment.
