Proverbs 10:31 teaches that a person who lives rightly will speak wisdom, while a person who speaks deceit and cruelty will eventually lose the ability to speak at all. The verse is a contrast between two kinds of speech and the two kinds of people who produce them. It is a proverb from the book of Proverbs, traditionally attributed to Solomon, and it was written as a piece of practical instruction for a young person learning how to live well before God.
The mouth of the righteous produces wisdom, but the perverse tongue will be cut off.

What Proverbs 10:31 Means
The verse uses the image of a mouth that “produces” wisdom, as a garden produces fruit or a tree produces its harvest. Wisdom is not treated here as a mood or a private thought. It is something that comes out of a life that is rooted in what is right, and it shows up in ordinary conversation. The righteous person does not have to be clever or eloquent to speak wisely. What matters is that their words grow out of a character shaped by honesty and reverence for God.
The second half of the verse describes the “perverse tongue,” meaning speech that twists the truth, deceives, or hurts people on purpose. The phrase “will be cut off” is best read as a statement about the outcome of such a life. Proverbs repeatedly teaches that dishonest and destructive speech eventually isolates a person and undoes their standing, so the image points to a consequence that tends to unfold over time. The verse describes a general pattern that wisdom literature observes, not a guarantee that every liar will be struck down on a particular day.
It is also worth being clear about what the verse does not say. It does not promise that righteous people will always be believed, always be listened to, or always be rewarded in this life. It does not say that a wise person never makes mistakes or never speaks poorly. It describes a direction of travel: a life aligned with God tends to bear the fruit of trustworthy speech, and a life of deceit tends to collapse under its own dishonesty.
The Context of Proverbs 10:31
The book of Proverbs is a collection of short, memorable sayings meant to form character and guide daily decisions. Chapter 10 begins a major section containing many of the book’s best-known contrasts between the wise and the foolish, the righteous and the wicked. The audience is primarily a young man being trained in the ways of wisdom, though the principles apply to anyone who wants to live well. The sayings are meant to be memorized, pondered, and lived out rather than read once and set aside.
The verses just before and after Proverbs 10:31 help clarify its meaning. Verses 28 through 30 speak of the righteous having joy and stability, and verse 32 says the lips of the righteous know what is acceptable while the mouth of the wicked is perverse. Read in that setting, verse 31 is part of a larger picture in which speech reveals the heart. Because the surrounding verses are so focused on the difference between the upright and the wicked, the verse reads less like a rule about speaking and more like a description of what a transformed heart naturally produces.
Key Phrases in Proverbs 10:31
Ephesians 4:29
Let no corrupt speech proceed out of your mouth, but only what is good for building others up as the need may be, that it may give grace to those who hear.

Paul’s instruction that our speech should build others up and give grace to those who hear it expands Proverbs 10:31 by showing that wise speech is measured by its usefulness to others.
James 3:5-6
5 So the tongue is also a little member, and boasts great things. See how a small fire can spread to a large forest! 6 And the tongue is a fire. The world of iniquity among our members is the tongue, which defiles the whole body, and sets on fire the course of nature, and is set on fire by Gehenna.

James uses the image of a small spark setting a forest on fire to describe how the tongue can do great harm, which deepens the warning that the perverse tongue carries serious consequences.
A Short Prayer From Proverbs 10:31
Lord, you know the words I have spoken today and the words I am tempted to speak tomorrow. Shape my heart so that my speech comes from a place of honesty and care for others. Where I have twisted the truth or spoken carelessly, forgive me, and help me to make things right. Let my mouth bring forth what is wise and good, so that my words point others toward you. Amen.
