Proverbs 15:2

Wisdom uses speech skillfully to communicate knowledge, but fools expose their folly through reckless words.

Proverbs 15:2 teaches that wise speech handles knowledge carefully and constructively, whereas the speech of fools pours out folly without restraint.

1. Gentle Speech, Knowledge, and the LORD's Seeing The chapter opens with one of its major themes: a gentle answer turns away wrath, but a harsh word stirs up anger. The tongue of the wise adorns knowledge, while the mouth of the fool gushes folly. The eyes of the Lord are everywhere, keeping watch on the wicked and the good. The soothing tongue is a tree of life, but a perverse tongue crushes the spirit.
2. Correction, Righteous Treasure, and Scattered Knowledge A fool spurns a parent's discipline, while the prudent heed correction. The house of the righteous contains great treasure, but the income of the wicked brings ruin. The lips of the wise spread knowledge, but the hearts of fools do not.
3. Worship, Prayer, and the LORD's Delight The Lord detests the sacrifice of the wicked but delights in the prayer of the upright. He detests the way of the wicked but loves those who pursue righteousness. Stern discipline awaits anyone who leaves the path, and the one who hates correction will die. Death and Destruction lie open before the Lord, how much more human hearts.
4. Mockers, Cheerful Hearts, and the Search for Knowledge Mockers resent correction and avoid the wise. A happy heart makes the face cheerful, while heartache crushes the spirit. The discerning heart seeks knowledge, but the mouth of a fool feeds on folly. The oppressed have days filled with trouble, but a cheerful heart has a continual feast.
5. Fear of the LORD, Love, Patience, and the Path Better is little with the fear of the Lord than great wealth with turmoil. Better is a small serving of vegetables with love than a fattened calf with hatred. A hot-tempered person stirs conflict, but patience calms a quarrel. The way of the sluggard is blocked with thorns, but the path of the upright is a highway.
6. Wise Children, Folly, Plans, and Joyful Words A wise son brings joy to His father, while a foolish person despises His mother. Folly delights one who has no sense, but whoever has understanding keeps a straight course. Plans fail for lack of counsel, but with many advisers they succeed. A person finds joy in giving an apt reply, and a timely word is good.
7. The Upward Path, Pride, Greed, and Righteous Speech The path of life leads upward for the prudent, keeping them from the realm of the dead below. The Lord tears down the house of the proud but sets the widow's boundary stones in place. The Lord detests the thoughts of the wicked, but gracious words are pure in His sight. The greedy bring ruin to their households, but those who hate bribes will live. The heart of the righteous weighs its answers, but the mouth of the wicked gushes evil. The Lord is far from the wicked, but hears the prayer of the righteous.
8. Light, Good News, Life-Giving Correction, and Humility Light in a messenger's eyes brings joy to the heart, and good news gives health to the bones. Whoever heeds life-giving correction will be at home among the wise. Those who disregard discipline despise themselves, but whoever heeds correction gains understanding. Wisdom's instruction is to fear the Lord, and humility comes before honor.

• Do not interpret the proverb as praising clever rhetoric alone; the focus is on wisdom governing speech.
• Do not assume that possessing knowledge automatically produces wise speech; wisdom shapes both content and tone.
• Do not reduce the proverb to communication technique; it addresses the moral orientation of the heart.
• Do not overlook that foolish speech reveals the deeper problem of rejecting wisdom.
• Do not treat “adorns knowledge” as mere rhetorical polish; the contrast is moral—wisdom governs speech for the hearer’s good.
• Do not assume that having information equals wisdom; the proverb praises skillful handling and restraint, not raw data.
• Do not read the proverb as an absolute guarantee that wise words always persuade; it is a general wisdom observation about speech-character alignment.
• Do not reduce folly to personality quirks; “pouring out” folly describes a lack of discernment and restraint that can harm others.

• Measured speech is not silence for its own sake; it is wisdom shaping knowledge into words that help rather than harm.
• Reckless talk is a warning sign: when folly “pours out,” it often indicates a deeper refusal to be taught or corrected.
• Growth in sanctification is visible in speech patterns: restraint, clarity, and constructive intent increasingly replace impulsive venting.
• Teachers, leaders, and parents must aim not only to be correct but to communicate knowledge in a fitting, hearer-serving way.
• In conflict, the wise aim to make truth understandable and healing; fools multiply words that expose confusion and intensify damage.
