Proverbs 15:2
The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.
Proverbs 15:2 (KJV)
Context
The book of Proverbs collects short, practical sayings that guide daily life. Its wisdom addresses speech, work, relationships, and character, inviting readers to live righteously before God and others. This verse focuses on speech, a major theme throughout the book.
Meaning
This verse contrasts two kinds of speech. The tongue of the wise “useth knowledge aright,” meaning the wise person shares knowledge at the right time, in the right place, and with the right person. The Hebrew word suggests using knowledge well, adapting it to the hearer for comfort, edification, and instruction. The wise heart is filled with useful knowledge—civil, moral, spiritual, and evangelical—and takes care to share it appropriately. Wisdom is not merely having information; it is applying it with discernment.
In contrast, the mouth of fools “poureth out foolishness.” The picture is of a gushing or boiling overflow, without restraint or filter. Fools speak hastily, carelessly, and harmfully, causing discord and confusion. Their words lack the discernment that marks wise speech.
Biblical connections
This teaching aligns with Proverbs 18:21, which states that death and life are in the power of the tongue. That verse directly reinforces the impact of wise and foolish speech described here: words carry weight and lasting effect, either building up or tearing down.
Application
Believers are called to use knowledge responsibly. Before speaking, consider the hearer’s need and the timing. Seek wisdom from God, guard your tongue, and let your words minister grace to others. This verse warns against careless speech and urges intentionality in conversation.
Pause before speaking to choose words that build up.
Ask God for discernment to share knowledge at the right moment.
Avoid hasty or careless speech that pours out folly.
Reflection
Our speech reveals the state of our hearts. A wise heart, filled with useful knowledge and reverence for God, will naturally speak what is good and fitting. Let this verse shape your conversations, so that your words bring life and honor to the Lord.
