Proverbs 15:7; Proverbs 15:14; Proverbs 15:20-21; Proverbs 15:24

7 The lips of the wise spread knowledge, but the hearts of fools are not upright.
14 The discerning heart seeks knowledge, but the mouth of a fool feeds on folly.
20 A wise son brings joy to his father, but a foolish man despises his mother. 21 Folly brings joy to one who has no sense, but whoever has understanding keeps a straight course.
24 The path of life leads upward for the prudent to keep them from going down to the realm of the dead.
