Psalm 73:9 describes arrogant people who speak as though they own the heavens and the earth, boasting against God and the people around them. The psalmist is observing the wicked, not endorsing their words, and he is writing about what he saw as he struggled to understand why such people seemed to prosper. The verse is part of a poem attributed to Asaph, a Levitical singer whose faith was tested by the apparent success of the proud.
They have set their mouth in the heavens. Their tongue walks through the earth.

What Psalm 73:9 Means
The phrase “they have set their mouth in the heavens” pictures someone whose words reach upward in open defiance, as if they had claimed the very sky as a platform for their boasts. In the Hebrew, the mouth is the instrument of speech, so this is not about physical location but about the audacity of what is said. It describes people who talk about God and heavenly matters with contempt or self-importance.
The second line, “their tongue walks through the earth,” shifts to the human sphere. The tongue moves freely across the land, spreading slander, lies, and intimidation wherever it goes. Together the two lines show speech that aims high against God and travels wide against people. The verse describes a condition of the heart and the words it produces; it does not promise that such people will escape notice or that their arrogance will last forever. The psalm as a whole goes on to show that God sees and judges.
The Context of Psalm 73:9
Psalm 73 belongs to the collection of psalms attributed to Asaph, and it is one of the wisdom psalms that wrestles openly with the problem of suffering and injustice. The psalmist admits that he nearly stumbled when he looked at the prosperity of the proud, who seemed untouched by the troubles that afflicted ordinary believers. The poem is addressed to the faithful, especially those tempted to envy the wicked and doubt that God’s justice is real.
Verses 6 through 8 describe the outward marks of pride: a chain of arrogance, violence like a garment, and speech full of malice. Verses 10 through 12 record what the wicked say about God (“How does God know?”) and their continued ease. Read in this setting, verse 9 is the heart of the psalmist’s complaint, but the turn comes later, when he enters the sanctuary and understands that the fate of the proud is far less secure than their boasting suggests.
Key Phrases in Psalm 73:9
Proverbs 18:21
Death and life are in the power of the tongue; those who love it will eat its fruit.
(WEB)
This proverb states plainly that the tongue holds the power of life and death, which explains why Psalm 73:9 treats careless and arrogant speech so seriously. Reading it alongside the psalm reminds you that words are not merely expressions of opinion but acts with real consequences for others and for your 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 fire that can set a whole forest ablaze, echoing the way Psalm 73:9 shows speech travelling across the earth to do damage. Together the two passages present the tongue as a small member with enormous reach, calling believers to watch it carefully.
A Short Prayer From Psalm 73:9
Lord, you see the proud who speak as if the heavens were theirs and the earth their stage. Keep my own mouth from boasting and my tongue from spreading what wounds others. When I am tempted to envy the people who seem to prosper by careless words, remind me that you know every heart and that your justice is sure. Give me words that honor you and build up those around me, and help me trust you to judge rightly in your time. Amen.
