Proverbs 10:8

The wise in heart will receive commandments: but a prating fool shall fall.

The wise in heart will receive commandments - namely, those of God, and of the servants of God, as to the right regulation of his heart and life ().

But a prating fool shall fall - one who pertinaciously defends his folly, and who can speak nothing except what betrays his folly-literally, 'a fool of lips.' The fool's lips, which are his prominent characteristic, are opposed to the wise man's heart, which is his characteristic. The fool is void of heart - i:e., understanding; therefore, in his self-sufficiency, he will not hear the commandments of God and of His servants; whereas the wise man, conscious of his own weakness, gladly hears the instructions of others.
