There are four primary characters in Proverbs: the wise, the fool, the simple, and the scoffer. The wise embrace God’s covenant. Fools, on the other hand, are opposed to God, yet they are not beyond hope. The simple are those who remain uncommitted to either wisdom or folly, and because of that they are easily misled. Scoffers are proud and arrogant and scorn God’s ways. Other voices in the book include Lady Wisdom and Lady Folly, each of whom personifies the characteristics of her name, and the Woman of Excellence, with whom the book concludes.
