Proverbs 15:2

¶ The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.

The tongue {H3956} of the wise {H2450} useth knowledge {H1847} aright {H3190}: but the mouth {H6310} of fools {H3684} poureth out {H5042} foolishness {H200}.

The tongue of the wise presents knowledge well, but the mouth of a fool spews out folly.

The tongue of the wise commends knowledge, but the mouth of the fool spouts folly.

The tongue of the wise uttereth knowledge aright; But the mouth of fools poureth out folly.

Proverbs 15:2 offers a concise yet profound contrast between the speech of the wise and the foolish, highlighting the direct correlation between one's character and their communication. This verse underscores a central theme in the book of Proverbs: the critical importance of words and their impact.

Context

The Book of Proverbs is a collection of ancient Israelite wisdom literature, primarily attributed to King Solomon. It offers practical guidance for living a righteous and fulfilling life in accordance with God's will. A recurring motif throughout Proverbs is the sharp distinction between wisdom (chokmah) and folly (ivveleth), often expressed through antithetical parallelism, where opposing ideas are presented in parallel lines. Speech is a particularly emphasized area, as the tongue is seen as a powerful instrument capable of great good or tremendous harm.

Key Themes

  • Discretion in Speech: The wise person doesn't just possess knowledge, but knows how to "use it aright" – to apply it appropriately, timely, and effectively through their words. Their speech is measured, thoughtful, and constructive.
  • Revelation of Character: Our words are a direct outflow of our inner being. A wise heart produces wise speech, while a foolish heart cannot help but "pour out foolishness." As Matthew 12:34 states, "out of the abundance of the heart the mouth speaketh."
  • The Power of the Tongue: This proverb implicitly acknowledges the immense influence of words. The wise tongue builds up and guides, while the fool's mouth can scatter and destroy. The book of Proverbs frequently emphasizes the power of life and death in the tongue.
  • Wisdom vs. Folly: The verse clearly delineates between those who possess true understanding and those who lack it, demonstrating that wisdom is not merely intellectual accumulation but practical application in daily life, especially in communication.

Linguistic Insights

  • "useth knowledge aright" (KJV): The Hebrew phrase for "useth knowledge aright" (יֵטִיב דַּעַת - yetiv da'at) implies guiding, nurturing, or making knowledge good. It's not just about speaking knowledgeably, but speaking knowledge in a way that is beneficial, skillful, and appropriate for the situation. It suggests a deliberate and beneficial application of understanding.
  • "poureth out foolishness": This vivid imagery suggests an uncontrolled, abundant gushing forth. The fool's words flow freely and without restraint, revealing an inner emptiness or corruption. There is no filter, no discretion, only an unthinking release of what is within. The Hebrew word for "foolishness" (אִוֶּלֶת - ivveleth) often points to a moral and spiritual deficiency, not just a lack of intelligence.

Practical Application

This proverb remains highly relevant for modern communication. In an age of instant messaging, social media, and constant interaction, the call to speak wisely is more urgent than ever.

  • Think Before You Speak: Before expressing an opinion or sharing information, consider whether your words are thoughtful, helpful, and appropriate. Are you using knowledge "aright," or simply "pouring out" whatever comes to mind?
  • Reflect on Your Heart: Our speech is a mirror of our inner character. If our words are consistently negative, critical, or foolish, it may indicate a need for deeper spiritual introspection and growth.
  • Cultivate Discretion: Seek to develop the wisdom to know when to speak and when to remain silent, what to say and how to say it. This principle resonates with the New Testament's call for wholesome speech that builds up.
  • Value Edifying Communication: Strive to use your words to encourage, teach, correct, and bring clarity, rather than to spread gossip, ignorance, or negativity. Compare with Proverbs 12:18, which speaks to rash words. Also, James 1:19 offers similar advice on controlling the tongue.
