Folly is joy to him that is destitute of wisdom: but a man of understanding walketh uprightly.
– Proverbs 15:21
Foolishness in Proverbs is a choice, or it is a consequence of rejecting wisdom’s instruction and correction. This proverb identifies folly as joy to those who are destitute of wisdom, or without understanding. Fools delight in folly as a sport and pleasure (Proverbs 10:23; 14:9). The word for understanding means intelligence and reason. It describes one who is skilled in discernment. The word for upright means straight, or direct. The discerning ones deliberately choose the way that is good (Proverbs 14:16; 16:17). This is a man who has good sense and considers the end (Proverbs 22:3).
