Psalms 89:17 Commentary: The Glory of Their Strength

Psalm 89 is attributed to Ethan the Ezrahite, a wise man mentioned alongside Solomon (1 Kings 4:31). Its structure is a covenant lament: it opens with praise for God's steadfast love and faithfulness to the Davidic covenant (vv.1, 37), then turns abruptly to a bitter complaint that God has rejected and humiliated the anointed king (vv.38, 52). Verse 17 belongs to the initial praise section, which describes the blessedness of the people who walk in the light of God’s presence (vv.15, 18). The surrounding verses set the stage: “Righteousness and justice are the foundation of your throne” (v.14), and those who learn to acclaim God “walk in the light of your presence” (v.15). The horn imagery is rooted in ancient Near Eastern symbolism, where an ox’s horn represented strength and vitality. In Israelite poetry, “exalting the horn” became a metaphor for military victory, royal power, and divine favor (1 Samuel 2:1, 10; Psalm 75:10; 92:10; 132:17). The phrase “glory of their strength” draws on the Hebrew concept of splendor or ornament (תפארת), the strength itself is not merely functional but beautiful because it reflects God. The literary context makes clear that this is a communal celebration: the poet speaks for a people whose identity and hope rest entirely on the God who chose David and made an everlasting covenant with him. The abrupt change of pronouns from “their” (v.17a) to “our” (v.17b) is a natural movement: the praise becomes personal as the poet joins the congregation in claiming the promise.

The consulted sources note one significant variant. In the second line, the Hebrew has a Kethib (written text) reading תָּרִים (tarim, “you will exalt our horn”) and a Qere (prescribed reading) tradition of תָּרוּם (tarum, “our horn will be exalted”). Clarke reports that forty-four of Kennicott’s manuscripts and sixty of De Rossi’s support the Qere, along with the Septuagint, Syriac, Vulgate, and Arabic versions. The Cambridge Bible notes that the Qere agrees with the LXX and Syriac, while the Kethib is supported by the Targum and Jerome. No other significant textual issues are raised by the sources.

Throughout church history, Psalm 89:17 has been read as a poetic summary of God’s grace in empowering His people. Early Christian writers saw the horn as a type of Christ’s exaltation, the fulfillment of God’s favor to David (Luke 1:69). In medieval devotional use, the verse was often paired with the surrounding lines to teach dependence on God rather than human merit. Reformation-era commentators such as Calvin and the Geneva Bible treated the verse within the covenantal framework of Psalm 89, emphasizing God’s faithfulness even in times of apparent abandonment. In more recent centuries, the verse has appeared in hymnody that celebrates God as the source of strength, though no specific hymn titles are preserved in the supplied sources. It continues to be used in Christian teaching to ground self-worth and confidence in God’s favor, not in personal achievement.

Three-point outline

1. God is the glory of our strength. Every ounce of ability, courage, or endurance we have is a gift. The glory does not belong to us; it reflects back on Him. We do not boast in our own resources but in the God who supplies them.
2. God’s favor exalts us. The horn is a symbol of power and influence. Real elevation, spiritual, relational, or even material, comes not from human striving but from the Lord’s good pleasure. He lifts whom He chooses.
3. We walk in the light of His presence. Verses 15, 16 show that those who know the joyful sound, the glad news of God’s reign, walk with confidence. Their strength is inseparable from their fellowship with God.

Five-point outline

1. Strength finds its true beauty in God (v.17a)
2. Favor, not effort, is the ground of exaltation (v.17b)
3. The people of God are defined by their boast in Him alone (cf. vv.15, 16)
4. The horn, our realm of influence, is safe only in His hands (cf. Psalm 75:10)
5. The covenant with David assures us that God’s purpose will stand (vv.19, 37)

Illustration hooks

• A runner who crosses the finish line and immediately points upward, acknowledging the gift of strength and breath, not to diminish the training, but to honor the Giver behind it.
• A parent watching their child succeed in a difficult exam; the pride they feel is not in the score itself but in the growth it represents. Likewise, God takes pleasure when His people’s strength reflects His character.

Questions your congregation is asking

• How can I know whether I am trusting God for my strength or relying on my own abilities?
• What does it look like for God’s favor to exalt someone in everyday life, a promotion, restored relationships, spiritual growth?

This verse calls us to examine where we place our confidence. The strength we have, whether physical, emotional, or spiritual, is a gift from God. And our exaltation comes from His favor, not our effort. In a culture that prizes self-reliance, this is both challenging and freeing. As you begin, read aloud the surrounding verses (Psalm 89:15, 18) to see the full picture of blessing.

Discussion questions

1. What does it mean that God is the “glory” of our strength? How does that affect the way you view your own abilities?
2. Read 1 Samuel 2:1 and Psalm 75:10. How does the horn imagery help you understand what “exaltation” looks like for God’s people?
3. In verse 17, the psalmist moves from “their” to “our.” Why does that shift matter? How does it reflect personal faith in a communal promise?
4. The context of Psalm 89 includes both praise and lament. How can this verse still be true when God’s people are suffering or seem abandoned?
5. Think of a time when you felt your “horn was exalted” by God’s favor, not by your own work. What changed in your perspective or circumstances?
6. How do you practically “acclaim” God (v.15) in your daily routines, especially when you feel weak?
7. This verse points to God’s covenant with David. How does that covenant find fulfillment in Christ, the ultimate horn of salvation (Psalm 132:17; Luke 1:69)?
