Meaning of "speak of Your faithfulness"?
What does it mean to "speak of Your faithfulness" in Psalm 40:9?

Setting the Scene in Psalm 40

• David sings after God rescues him (vv. 1-3).

• The psalm quickly turns from personal gratitude to public proclamation (vv. 9-10).

• Verse 10 (numbered 9 in some traditions) reads: “I have spoken of Your faithfulness and salvation; I have not concealed Your loving devotion and truth from the great assembly”.

• “Speak of Your faithfulness” is therefore part of a larger commitment: David refuses to hide anything God has done.


The Hebrew Color of “Speak”

• The verb translated “spoken” or “declared” is biśśarti—to announce good news, publish, spread the word.

• It implies energy and intentionality, not casual chit-chat.

• David isn’t whispering God’s virtues to a select few; he is broadcasting them to the “great assembly,” the gathered worshipers at the sanctuary.


What Scripture Means by “Your Faithfulness”

• Hebrew ’ĕmūnāh—steadfastness, reliability, firmness.

• God keeps covenant promises (Deuteronomy 7:9).

• His mercies are “new every morning” (Lamentations 3:23).

• He can be trusted in every circumstance (Psalm 89:1-2).

In short, David is vocal about the very character of God—His proven track record of doing exactly what He says.


Why David Must Speak

• Gratitude demands expression (Psalm 40:3).

• God’s salvation is too big to hide under personal privacy (cf. 1 Peter 2:9).

• Public testimony strengthens the faith of others (Psalm 34:2-3).

• Silence would dishonor the LORD’s mighty acts (Psalm 107:2).


Practical Ways to “Speak of His Faithfulness” Today

• Recount answered prayers in conversation and social media.

• Sing songs that highlight God’s unchanging nature (Colossians 3:16).

• Incorporate personal testimony when teaching children or leading small groups.

• Write down and share “faithfulness stories” in church newsletters or blogs.

• Celebrate ordinances like Communion with explicit reminders of His covenant faithfulness (1 Corinthians 11:25-26).


Key Takeaways

• To “speak of Your faithfulness” is to make God’s dependable character public knowledge.

• It involves active, vocal, and unashamed proclamation before the gathered people of God.

• Such speech honors the LORD, strengthens fellow believers, and invites unbelievers to trust the same faithful God.
