Psalm 140:3 on evil speech?
What does Psalm 140:3 reveal about the nature of evil speech?

Verse in Focus

“They sharpen their tongues like snakes; the venom of vipers is on their lips. Selah” (Psalm 140:3)


Key Observations from Psalm 140:3

• The verse paints evil speech in two vivid pictures—sharpened tongues and venomous lips.

• Both images carry a literal weight in Scripture: a sharpened blade cuts deliberately, and real viper venom is lethal.

• The psalm connects words and intent: malicious speech is neither accidental nor harmless.


What Evil Speech Looks Like

• Deliberate Preparation

– “They sharpen their tongues” indicates forethought, planning, and skill in harm (cf. Proverbs 12:18).

• Hidden Lethality

– Like snake fangs, hurtful words may strike suddenly and from concealment (Psalm 64:3–4).

• Poisonous After-effects

– Venom spreads beyond the bite; so slander, gossip, and deceit spread corruption long after the words are spoken (James 3:6).

• Alignment with a Sinful Nature

– Paul quotes this very imagery when describing humanity’s universal fallenness (Romans 3:13), underscoring that corrupt speech flows from an unredeemed heart (Luke 6:45).


Why Evil Speech Is So Dangerous

• It Destroys Life

– “Death and life are in the power of the tongue” (Proverbs 18:21). Venom is fatal; so can words be to reputations, relationships, and spiritual vitality.

• It Multiplies Sin

James 3:5–8 compares the tongue to “a fire” that sets “the course of one’s life on fire,” producing further evil.

• It Opposes God’s Truth

– Lying and deceit align with the devil, “a liar and the father of lies” (John 8:44). Evil speech betrays allegiance.


Guarding Our Own Tongues

• Daily Surrender

– Pray with David, “Set a guard, O LORD, over my mouth” (Psalm 141:3).

• Fill the Heart with Truth

– Meditate on Scripture; a heart brimming with God’s Word overflows with grace (Colossians 3:16).

• Choose Edification

– “Let no unwholesome talk come out of your mouths, but only what is helpful for building up” (Ephesians 4:29).

• Swift Repentance

– When we sin with our words, confess immediately (1 John 1:9) and make restitution where possible.


Living Words That Heal

Evil speech mirrors a serpent’s strike, but redeemed speech mirrors Christ, “full of grace and truth” (John 1:14). Speaking life, blessing, and truth counters the poison and showcases the transforming power of the gospel.

How can we guard against 'tongues as sharp as a serpent's' in daily life?
