The tongue of the wise commends knowledgeThis phrase emphasizes the value of wisdom in communication. In biblical context, wisdom is often associated with the fear of the Lord (
Proverbs 9:10) and is considered a divine gift. The wise person uses their speech to promote understanding and truth, reflecting the biblical principle that words have the power to build up or tear down (
Proverbs 18:21). The Hebrew culture placed a high value on oral tradition and the spoken word, which was a primary means of teaching and preserving knowledge. This aligns with the New Testament teaching in
James 3:13, where wisdom is demonstrated through good conduct and humility. The wise tongue is a type of Christ, who is described as the Word made flesh (
John 1:14), embodying perfect wisdom and truth.
but the mouth of the fool spouts folly
In contrast, this phrase highlights the destructive nature of foolish speech. In the biblical context, a fool is not merely someone lacking intelligence but is often characterized by moral and spiritual deficiency, rejecting God's wisdom (Psalm 14:1). The fool's speech is reckless and devoid of understanding, leading to chaos and harm. This is consistent with the cultural understanding of folly in ancient Israel, where speech was a reflection of one's character and relationship with God. The imagery of "spouting" suggests an uncontrolled and excessive outpouring, akin to a fountain that cannot be stopped, which is echoed inJames 3:5-6, where the tongue is described as a small part of the body that can cause great destruction. This serves as a warning against careless words and aligns with the broader biblical narrative that emphasizes the importance of self-control and discernment in speech.

The tongue of the wise“The tongue of the wise” (Proverbs 15:2a) points to men and women whose hearts have been shaped by God’s Word.
• Wisdom in Scripture is never merely intellectual; it is a Spirit-formed character that shows up first in conversation (James 3:13;Colossians 4:6).
• When the heart is aligned with God, the tongue follows, much likeProverbs 10:32 says, “The lips of the righteous know what is fitting.”
• Wise speech is intentional. It slows down long enough to listen (James 1:19) and refuses to weaponize words.
Commends knowledge“…commends knowledge” (15:2b) shows the purpose of wise speech: to put useful, godly truth on display.
• The verb carries the picture of making knowledge attractive—like arranging apples of gold in settings of silver (Proverbs 25:11).
• Wise words:
– Clarify truth without condescension (1 Peter 3:15).
– Build faith, not fear (Proverbs 16:23).
– Redirect conversations toward Christ, the embodiment of all wisdom (Colossians 2:3).
• A believer’s tongue becomes a living classroom where God’s knowledge is showcased.
But the mouth of the foolIn stark contrast, “the mouth of the fool” (15:2c) describes a life untouched by reverence for the Lord (Proverbs 1:7).
• A fool may possess information, but he lacks submission; therefore, his words are reckless (Proverbs 18:6-7).
• His mouth exposes his heart, as Jesus teaches inMatthew 12:35: “The good man brings good things out of his good treasure, and the evil man brings evil things out of his evil treasure.”
• The fool’s speech often escalates conflict, blinds himself to correction (Proverbs 12:15), and isolates him from wise counsel (Ecclesiastes 10:12).
Spouts folly“…spouts folly” (15:2d) pictures a gushing spring—continual, uncontrolled, and destructive.
• The imagery parallelsProverbs 29:11: “A fool vents all his anger, but a wise man holds it back.”
• Folly pours out:
– Rash promises (Proverbs 20:25).
– Gossip that wounds reputations (Proverbs 16:28).
– Arguments that scatter relationships (Proverbs 15:18).
• What fills the heart determines what flows from the mouth; unchecked, folly spreads like wildfire (James 3:6).
summaryProverbs 15:2 draws a sharp line: wisdom and folly are most visible in everyday conversation. A wise tongue, rooted in fear of the Lord, turns speech into a platform for truth, clarity, and grace. A foolish mouth, untethered from God, becomes a fountain of harm. Believers are called to cultivate hearts saturated with Scripture so that, in every setting, their words consistently “commend knowledge.”
XV.(2)Useth knowledge aright.--Brings it forth at the proper time and place.
Verse 2. -
The tongue of the wise useth knowledge aright. This means either, brings it forth opportunely, it the right time and place, or illustrates it, makes it beautiful and pleasant, as ver. 13. The wise man not only has knowledge, but can give it appropriate expression (comp.
Proverbs 16:23). Vulgate, "The tongue of the wise adorneth wisdom." The wise man, by producing his sentiments and opinions in appropriate language and on proper occasions, commends wisdom, and renders it acceptable to his hearers. Septuagint, "The tongue of the wise knoweth what is fair (
καλά)."
But the mouth of fools poureth out foolishness (ver. 28). A fool cannot open his mouth without exposing his folly; he speaks without due consideration or discretion; as the Vulgate terms it,
ebullit, "he bubbles over," like a boiling pot, which emits its contents inopportunely and uselessly. Septuagint, "The mouth of fools proclaimeth evil."
