The sense of the words thus rendered is this, All this he performeth by that discretion which God hath put into him; and therefore be assured that God will order all his affairs with judgment, and will in due season execute the punishments which now he threatens, and will perfect his own works. But the words by some are rendered otherwise. And he beateth it out (as this word may be rendered, 1 Kings 12:11 Proverbs 19:18, Proverbs 29:17) in such sort as his God doth teach him; in a discreet manner, which being generally mentioned here, is particularly described in the following verse.
