Psalm 5:9 and James 3:8 on the tongue?
How does Psalm 5:9 connect with James 3:8 about controlling the tongue?

Setting the scene with the two verses

“ For there is no truth in their mouth; their heart is destruction; their throat is an open grave; with their tongue they speak deceit.” (Psalm 5:9)

“ But no man can tame the tongue. It is a restless evil, full of deadly poison.” (James 3:8)


Shared diagnosis: the tongue reveals the heart

• Both texts expose speech as a window into the inner person.

Psalm 5:9 traces deceitful words to a heart of “destruction.”

James 3:8 widens the scope, stating that the tongue is untamable by human effort, showing an inherent sin problem.


Psalm 5:9: corruption flowing outward

• Vocabulary of death: “throat is an open grave” pictures speech that spreads decay.

• Falsehood originates in a corrupt heart (“no truth in their mouth”).

• Parallel passages: Psalm 140:3; Romans 3:13 echo the same imagery of poisonous speech.


James 3:8: universal inability

• “No man can tame the tongue” underscores our complete insufficiency.

• The tongue’s “deadly poison” mirrors the “open grave” image—death-laced language.

• James unites all people under this indictment, not just the openly wicked.


How the passages connect

Psalm 5:9 provides a portrait of the wicked; James 3:8 shows that, apart from grace, everyone shares that condition.

• Both verses declare the tongue naturally lethal, stressing the need for divine intervention, not mere self-discipline.


Divine remedy and daily practice

• New heart promised in Ezekiel 36:26-27 makes righteous speech possible.

• Indwelling Spirit produces “self-control” (Galatians 5:22-23) that James says humans lack on their own.

• Practical steps enabled by grace:

– Fill the heart with truth (Psalm 119:11).

– Yield speech to the Spirit’s control (Ephesians 4:29-30).

– Engage in continual repentance when words misfire (1 John 1:9).


Living it out

Psalm 19:14 models a Spirit-shaped desire: “May the words of my mouth and the meditation of my heart be pleasing in Your sight, O LORD…”

• As the new heart is daily renewed by Scripture and the Spirit, the tongue, once “full of deadly poison,” becomes an instrument of blessing (James 3:9-10; Proverbs 15:4).
