Psalm 34:13 is a plain call to control your speech: guard your tongue from what is harmful and keep your lips from falsehood. It is written as a piece of practical wisdom, the kind a parent or teacher gives to a child who is learning how to live well. King David, traditionally credited with this psalm, speaks it to those who want to know the fear of the LORD and to enjoy a good life.
Keep your tongue from evil, and your lips from speaking lies.

What Psalm 34:13 Means
The verse begins with the tongue, the small organ that can do great damage. “Keep” suggests active guarding, the way you would keep a gate closed against an intruder or keep a fire from spreading. David is not asking for a few careful words now and then. He is describing a steady watchfulness over what leaves your mouth. The phrase “from evil” points to speech that wounds, deceives, slanders, or stirs up trouble.
The second half widens the picture to “your lips,” which means your whole manner of speaking. Lying is singled out because it is a direct betrayal of truth, and in a community where people depend on one another’s word, a lie eats away at trust. The verse does not promise that a careful tongue will make life easy or protect you from every hard situation. It describes a way of living that fits with a life of faith and goodness, and it trusts that such a life is worth the effort.
The Context of Psalm 34:13
Psalm 34 is part of the book of Psalms, a collection of prayers and songs used by Israel in worship and personal devotion. The superscription ties this psalm to the time David pretended to be insane before King Achish of Gath, and many readers take the psalm as a song of thanksgiving for deliverance. That background matters, because David writes as someone who has been rescued and wants to pass on what he has learned to others.
The verses just before and after show why verse 13 sits where it does. Verse 10 promises that those who seek the LORD will lack no good thing, and verse 11 invites the listener to be taught the fear of the LORD. Verse 12 asks who truly wants a good life, and verse 13 answers by naming the first practical step. Verses 14 and 15 follow with the instruction to depart from evil, do good, and pursue peace, along with the reminder that the LORD watches over the righteous. Read this way, the tongue is one of the most immediate places where a person either pursues peace or breaks it.
Key Phrases in Psalm 34:13
Proverbs 12:22
Lying lips are an abomination to the LORD, but those who do the truth are his delight.
(WEB)
This proverb states plainly that lying lips are disgusting to the LORD while those who act faithfully delight him. It reinforces the honesty theme in Psalm 34:13 and shows that truthfulness is tied to God’s own character.
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.
(WEB)
James compares the tongue to a small spark that can set a large forest on fire. His image helps explain why David cared so much about guarding speech, since a careless word can cause damage far beyond what it seems to be.
A Short Prayer From Psalm 34:13
Lord, you know how quickly my words can run ahead of my good intentions. Help me to keep watch over my tongue today, so that I do not speak what hurts or what is untrue.
