The heart of him that hath understanding seeketh knowledge: but the mouth of fools feedeth on foolishness.
– Proverbs 15:14
The word for seeketh means to search out and indicates a deliberate search. The word for knowledge means cunning, perception, and discernment. Proverbs presents wisdom as accessible to all (Proverbs 8:1-11; 9:1-6), but acquired only by those who seek for it (Proverbs 2:1-6). One of the marks of wisdom is to continue to seek for wisdom (Proverbs 1:5; 9:9). The contrast speaks of feeding on foolishness rather than seeking wisdom. The word for feedeth means to pasture, or graze. The word for fools is the most common word in Proverbs for fools. The word means stupid and obstinate. The usage in Proverbs shows the word describes one who chooses the way of folly and not one who is mentally impaired. The fool gobbles up foolishness and spews it out freely (Proverbs 15:2). The fool has no heart or patience for acquiring wisdom (Proverbs 17:6, 24). He prefers his easy foolishness so much he returns to it like a dog to its own vomit (Proverbs 26:11).
