Psalms 5:9
For there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue.
Psalms 5:9
David laments the deceitfulness of adversaries: “there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue.” This vivid, prophetic-poetic critique targets the corruption of those who mouth smooth words while inwardly plotting harm. The image of the throat as a “sepulchre” portrays speech as deadly, a moral infection that harms others. In ancient Near Eastern diplomacy, flattery was a common tool—the appearance of loyalty while plotting against one’s neighbor. David’s agricultural imagery—sincerity on the inside and deceit on the outside—reflects a worldview where character is judged by words and deeds. The psalm functions as a communal lament, naming false voices that disrupt justice and trust within the community. The use of direct, unflinching language demonstrates the seriousness with which Scripture treats truth-telling and integrity in public life.
Trust in God’s justice requires discernment about those who wield words for harm. Theologically, this verse contrasts godly speech—truthful, faithful, edifying—with corrupt speech—wicked, deceitful, manipulative. It foreshadows New Testament warnings about the danger of the tongue (James 3) and calls believers to pursue truthfulness in all interactions. It also reinforces the need for divine judgment against oppression and manipulation, while inviting reliance on God’s righteous judgment rather than human vengeance. In short, integrity of speech is a marker of spiritual health and alignment with God’s character.
Practically, reflect on your own speech: do your words reveal faithfulness or flattery? Consider times when you’ve spoken smooth words to avoid conflict, only to regret it later. Resolve to speak truth with gentleness (Ephesians 4:15) and to curb sarcasm or backbiting. In a workplace, identify “open sepulchres” in conversations—covert manipulation, gossip, or misrepresentation—and choose to counter with honesty and transparency. If you encounter flattery toward you, test motives and seek accountability. When you hear people who hurt others with deceit, pray for justice and for opportunities to show mercy or truth-telling that protects the vulnerable. This verse challenges believers to cultivate a tongue that honors God and serves others, not one that advances self-interest through manipulation.
