The wise in heart will receive commandments,.... Such who have true wisdom in the hidden part of the heart, of which the fear of the Lord is the beginning: these will not only, as good subjects, honour their king, and attend to his lawful commands; and, as dutiful children, regard those of their parents; and, as faithful servants, hearken to those of their masters; but, as such that fear the Lord, will receive and cheerfully obey the commandments of God and Christ; but a prating fool shall fall; like Diotrephes, that prated against the Apostle John and other saints. Or, "a fool of lips" (b); whose folly is proclaimed and made known by his lips; who, out of the abundance of it in his heart, speaks and pours it out by his lips: such an one falls into sin and into mischief; he falls into disgrace in this world, and into hell in the next. The Targum is, "the fool by his lips shall be taken;'' as in a snare. (b) "stultus labiis", Montanus, &c.
