Psalm 109:30 is a vow of public thanksgiving. The psalmist promises to thank the LORD out loud and to praise him in front of a crowd, even while under attack. The verse is spoken by David, the traditional author of the psalm, in the middle of a prayer for justice against people who have wronged him.
I will give great thanks to the LORD with my mouth. Yes, I will praise him among the multitude.

What Psalm 109:30 Means
The phrase “I will give great thanks to the LORD with my mouth” describes thanks that is spoken aloud rather than kept quietly in the heart. The psalmist is making a deliberate decision to voice gratitude to God, which is an act of trust before the outcome has arrived.
The second sentence, “Yes, I will praise him among the multitude,” widens the picture. The thanks is not private. It is offered where other people can hear it, so that God’s faithfulness becomes something the whole gathering can recognize. The verse is less a promise that good things will happen and more a commitment to honor God whatever happens.
Notice what the verse does not say. It does not claim that the enemies have already been defeated, or that the pain has ended. The thanks comes in the middle of the struggle, which is what makes it striking.
The Context of Psalm 109:30
Psalm 109 belongs to the Psalter, the collection of songs and prayers in the Old Testament book of Psalms, and it is one of the sharpest prayers for justice in that collection. Its opening lines and much of its middle describe a person who has been slandered and betrayed, and the psalmist asks God to answer that wrong. Verses 27 and 28 ask that people will see God’s hand in what happens, and then contrast the enemies’ curses with God’s blessing.
Read in that setting, verse 30 is the turn toward thanksgiving. Verse 29 is still a prayer that the adversaries be clothed in shame, and verse 31 moves to God standing beside the needy person. Verse 30 sits between the plea for judgment and the assurance of God’s protection, so the thanks is not a denial of the hurt but a response of faith within it.

Lord, I want to thank you with my words today, even when my heart feels heavy and the situation around me is not resolved. You have been faithful to me in the past, and I choose to name that faithfulness out loud.

Let my thanks be heard by the people around me, so that they too may see that you are good. Amen.
