Psalm 36:3 describes a person whose speech is dishonest and harmful, and who has stopped acting with wisdom and goodness. In plain terms, the verse says that when someone’s words are full of falsehood and wrongdoing, it is a sign they have drifted away from what is wise and right. The psalm was written by David, the king of Israel, who describes the wicked person he observes in the verses around it.
The words of his mouth are iniquity and deceit. He has ceased to be wise and to do good.

What Psalm 36:3 Means
The first phrase, “the words of his mouth,” points to speech as the window into a person’s character. Words are where inner attitudes come out into the open. When David says those words are “iniquity and deceit,” he means they carry wrongdoing and are built on lies or manipulation. The speaker is not simply mistaken; his language is aimed at harm and at hiding the truth.
The second sentence shifts from speech to conduct. “He has ceased to be wise and to do good” describes someone who has stopped choosing wisdom and stopped doing good, as a settled direction rather than a single bad moment. The verse does not promise that such a person will be exposed at once, and it does not give a timetable for judgment. It diagnoses a condition and leaves the outcome to God, whose justice David describes in the verses that follow.
The Context of Psalm 36:3
Psalm 36 is a psalm attributed to David, and it is written as a meditation on two very different kinds of people. Verses 1 and 2 describe the wicked man who flatters himself and has no reverence for God. Verse 3 then gives the evidence of that inner condition in what he says and how he behaves. The psalm was likely sung or read by Israelites worshipping in the temple, who needed to be reminded that the wicked are real and that God sees them.
The verses that come just after Psalm 36:3 turn sharply toward God. Verses 5 and 6 speak of his steadfast love, faithfulness, and righteousness reaching to the heavens and the mountains. Because of that shift, the description of the wicked person reads as a contrast rather than a final word. David is saying that human corruption is serious, but God’s character is far greater, and the psalm ends in trust rather than despair.
Key Phrases in Psalm 36:3
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 an abomination to the LORD while those who act faithfully delight him. It shows the same concern for truthful speech that Psalm 36:3 expresses, and it offers a positive picture of the faithful person whose words match their integrity.
James 3:5
So the tongue is also a little member, and boasts great things. See how a small fire can spread to a large forest!
(WEB)
James compares the tongue to a small spark that can set a large forest on fire. His image helps explain why David links the words of the wicked to such serious consequences, and it encourages readers to see their own speech as a matter of real spiritual weight.
A Short Prayer From Psalm 36:3
Lord, you see what I say when I am alone and what I say when others are listening. Search my heart and show me where my words have drifted from honesty and kindness. Give me the wisdom to speak truth with care, and the courage to stop when I am tempted to deceive or wound. Keep my mouth in line with what is good, and let my life reflect your faithfulness. Amen.
