Psalms 73:9 Commentary: Arrogant Speech Against Heaven and Earth

Psalm 73 is a wisdom psalm attributed to Asaph, one of David’s chief musicians. Its central tension is the prosperity of the wicked versus the suffering of the righteous, a problem that nearly causes the psalmist to lose faith. Verses 3, 8 build a portrait of the wicked’s pride: they are free from burdens (v5), wear violence like clothing (v6), and speak with malice (v8). Verse 9 is the climax of that portrait.

In ancient Israel, heaven was understood as God’s dwelling place, the throne from which He ruled. To “set one’s mouth in the heavens” meant speaking as though one occupied that throne. This was not merely casual sin; it was a direct challenge to God’s sovereignty. The phrase echoes the language of later enemies like the king of Babylon (Isaiah 14) and the little horn of Daniel (Daniel 7:25).

The second line, “their tongue walks through the earth,” pictures speech that has no boundary. In a world without mass media, the image of a tongue wandering the earth conveyed total reach, their slander and blasphemy touched everyone. The psalmist himself felt the weight of it, admitting his feet nearly slipped (v2). Only when he entered the sanctuary did he understand the wicked’s end (v17). The historical context reminds us that the prosperity of the arrogant is temporary, and their speech will not escape God’s notice.

The supplied sources and standard critical editions note no significant manuscript variants for Psalm 73:9. The Hebrew text is stable. The differences among English translations arise from the semantic range of the preposition be- (ב), which can mean “in,” “against,” or “by.” Some versions (KJV, BSB) choose “against,” highlighting the adversarial stance; others (WEB, ASV) retain the spatial sense “in,” reflecting the idea of speaking from heaven. Both are grammatically defensible and do not alter the core meaning of arrogant speech directed toward God.

Psalm 73:9 has been used throughout church history to illustrate the height of human pride against God. Early Christian writers saw it as a portrait of the enemies of the gospel. The verse echoes in Revelation 13:6, where the beast opens its mouth in blasphemy against God. Medieval exegetes read it as a warning against the sin of pride, one of the seven deadly sins. Reformed commentators like Calvin placed it within the psalmist’s larger struggle with theodicy, emphasizing that such arrogance will be answered by God’s judgment. In more recent centuries, preachers have paired this verse with James 3 on the untamable tongue, and it appears in hymns that contrast human boasting with the majesty of God. The verse remains a powerful reminder that speech reveals the heart’s true allegiance.

Three-point outline

1. The Height of Arrogance: They set their mouth in the heavens, speaking against God’s authority, as if they were above Him.
2. The Spread of Corruption: Their tongue walks through the earth, nothing restrains their harmful words; every person and place is affected.
3. The Certainty of Judgment: The psalmist later sees their end (v17, 20); pride and speech will be answered by God.

Five-point outline

1. Setting the mouth against God: Direct blasphemy and mockery of His ways (Clarke, Gill).
2. Claiming divine authority: They speak as if they were ruling from heaven (Barnes, Cambridge).
3. Speaking without restraint: The tongue walks, continuous, unchecked, roaming everywhere.
4. Impacting the community: Their words draw others to follow them (v10) and slander the righteous.
5. Contrast with humility: The psalmist’s own mouth is eventually silenced before God (v21, 22).

Illustration hooks

• A CEO who speaks to employees as if they were omniscient and beyond criticism, demanding unquestioning loyalty.
• Social media posts that mock faith, claim superior knowledge, and spread without boundary, each a tongue walking through the earth.
• The small flame of a match setting a whole forest ablaze (James 3:5, 6); one arrogant word can destroy relationships and reputations.

Questions your congregation is asking

• Why do people who mock God seem to get away with it?
• How do I keep from envying their apparent success?
• What do my own words reveal about where my heart is set?

This verse sits at the center of a psalm that wrestles with one of faith’s hardest questions: why do the wicked prosper? The answer doesn’t come from logic but from entering God’s presence. Before that, the psalmist describes the wicked’s speech as the ultimate expression of pride. Their mouth is set in heaven; their tongue roams the earth. Use these questions to explore what this says about human sin and divine patience.

Discussion questions

1. Read Psalm 73:1, 9. What specific details about the wicked’s behavior trouble the psalmist? Why does he focus on their speech in verse 9?
2. The Hebrew phrase “set their mouth in the heavens” can be read as “against the heavens.” How does that small preposition change the meaning? What do the different translations tell us?
3. Barnes notes that the wicked speak “as if they were superior beings.” Where do you see this kind of speech in the world today?
4. The psalmist says their tongue “walks through the earth” (v9). How does this image compare to James 3:6, which calls the tongue “a fire” that “defiles the whole body”?
5. Why does the psalmist include the effect of their speech on others in verse 10? How does the arrogance of a few influence many?
6. How does the psalmist’s eventual turn to the sanctuary (v17) change his perspective? What does that teach about how we should respond when we are tempted to envy the proud?
7. If the wicked’s speech is this unrestrained, what hope is there for our own words? What does it mean to set our mouth in the heavens in a positive sense, to speak of God rather than against Him?
