⁷ The lips of the wise spread knowledge;
    not so with the heart of fools.

¹⁴ The heart of one who has understanding seeks knowledge,
    but the mouths of fools feed on folly.

²⁰ A wise son makes a father glad,
    but a foolish man despises his mother.
²¹ Folly is joy to one who is void of wisdom,
    but a man of understanding keeps his way straight.

²⁴ The path of life leads upward for the wise,
    to keep him from going downward to Sheol.^[a]
