What does the Bible say about wisdom and foolishness?

In Proverbs 10, the contrasts between the wise and foolish illustrate fundamental differences in character and outcomes. The wise are described as those who heed God's commandments and live righteously, while fools are those who deny God's existence and follow their own understanding. The chapter encapsulates ten distinct contrasts but emphasizes that all these differences ultimately stem from God's sovereign choice, highlighting that wisdom is not a human achievement but a divine gift.
