Y aun hasta la vejez y las canas; oh Dios, no me desampares, hasta que denuncie tu brazo á la posteridad, tus valentías á todos los que han de venir.
E agora, que estou velho e de cabelos grisalhos, não me desampares, Deus; enquanto eu não tiver anunciado a força de teu braço a esta geração, e teu poder a todos que vierem.
Ne m’ abandonne pas, ô Dieu! Même dans la blanche vieillesse,
Auch verlaß mich nicht, Gott, im Alter, wenn ich grau werde, bis ich deinen Arm verkündige Kindeskindern und deine Kraft allen, die noch kommen sollen.
Daarom ook, terwijl de ouderdom en grijsheid daar is, verlaat mij niet, o God, totdat ik dezen geslachte verkondige Uw arm, allen nakomelingen Uw macht.
Ed anche quando sia giunto alla vecchiaia ed alla canizie, o Dio, non abbandonarmi, finché non abbia fatto conoscere il tuo braccio a questa generazione, e la tua potenza a quelli che verranno.
A przetoż aż do starości i sędziwości nie opuszczaj mię, Boże! aż opowiem ramię twoje temu narodowi, i wszystkim potomkom moc twoję.
Благословен Господь Бог, Бог Израилев, един творящий чудеса,
神啊，我到 年老 髮白的時候，求你不要 離棄我！等 我將你的能力 指示 下代，將你的大能指示 後世的人。
Now when I am old and grey-headed, O God, give me not up; till I have made clear your strength to this generation, and your power to all those to come.

Scholars' Consensus
Commentators across traditions agree that this verse captures an aging believer’s urgent prayer for continued life, not for ease but for the specific task of passing on testimony. Barnes notes that the Hebrew word zro‘a (“arm”) symbolizes God’s active power in deliverance, not abstract strength. Gill links this arm to the Messiah, suggesting the psalmist desires to prophesy of Christ’s work. Calvin and Matthew Henry emphasize the duty to praise God and train the next generation. Keil and Delitzsch observe that the psalmist “will find new matter and ground and motive for the praise of God”, continued life fuels continued witness. The prayer “forsake me not” is less a fear of abandonment and more a request for strength to complete this mission. The consensus: old age is not a time for withdrawal but for purposeful declaration to those who follow.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Personal petition of an aged believer: The psalmist speaks in first person, refers to his own youth and old age (vv.5,9,17), and asks for personal deliverance (v.2,4).
- Corporate voice of Israel: The shift to plural in v.20 ('bring us up') suggests the speaker may represent the nation; Lange notes a change from singular to plural.
- Eschatological prophecy of the Messiah: Gill identifies 'thine arm' with the Messiah (Isa 53:1) and sees the declaration as prophetic witness to Christ’s work.
What is clear: The psalmist urgently desires to proclaim God’s mighty deeds before he dies, and asks God to sustain him for that purpose.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Speaker identity | The psalmist is an aging individual, likely David or a representative of the faithful community. | Some commentators (Lange, Keil & Delitzsch) suggest a corporate reading where the people of Israel speak as an aging entity, while others (Calvin, Matthew Henry) read it as a personal prayer of David. |
| The nature of the petition 'forsake me not' | It is a plea for God’s continued presence and help in old age. | Traditions differ on whether this is a conditional prayer: some see it as a request to complete a specific task before death, while others view it as a general plea for lifelong faithfulness (Barnes, Gill). |
| Who is the 'next generation'? | It refers to those who come after, both the current younger generation and future descendants. | Gill interprets this eschatologically, including the Messiah’s arm; Barnes sees it as the literal contemporary generation and all future generations. No major conflict. |
| The meaning of 'arm' (zro‘a) | It symbolises God’s power, especially in deliverance. | Some (Cambridge Bible, Kay) expand it to include guidance, protection, government; Gill identifies it with the Messiah. |
Historical & Cultural Context
In ancient Israel, old age was both honored and vulnerable. The psalmist’s repeated reference to “old and gray-headed” (also in v.9) signals not simply longevity but accumulated experience of God’s faithfulness, and the physical fragility that makes one dependent. Calvin and Poole connect this psalm to Absalom’s rebellion, when David was elderly and fleeing his own son. The Hebrew zro‘a (“arm”) echoes Exodus language (Ex 6:6, 15:16), where God’s outstretched arm redeems Israel from bondage. The request to declare God’s strength to “this generation” and “everyone who is to come” aligns with Deuteronomy 6:7 and Exodus 13:8, commands to tell children the story of salvation. The dual audience, present contemporaries and all future people, shows that the psalmist thinks beyond his own life. Lange notes that the psalm borrows phrases from older psalms (31, 35, 70), suggesting a king or leader who knows the tradition and wants to extend it. In a culture where oral transmission was central, this prayer is both personal and communal. The plea not to be forsaken until the task is done binds personal survival to the community’s need for faithful witnesses.

Reception History
This verse has long been associated with old age and the passing of faith. In Jewish tradition, it is recited as a prayer for longevity with purpose. Early Christian writers saw it as a model for aged believers to continue in witness. Protestant reformers such as Calvin and Matthew Henry used it to encourage faithfulness to the end. The phrase “declaring God’s arm” appears in hymns about God’s mighty acts, and the verse remains a favourite for retirement and legacy services.

- The Urgent Mission: His purpose: to declare God’s arm (strength) to the next generation. The Hebrew zro‘a suggests not just power but personal guidance and deliverance (Cambridge Bible). This is a specific, generational task.
- The Promise in the Prayer: “Don’t forsake me until…” reveals trust. God answers not by extending years alone but by empowering witness. The psalmist’s life has meaning beyond himself.
Five-point outline
- Old Age as Opportunity: Instead of retirement from faith, the psalmist sees a deadline, he must speak while he lives.
- The Content of the Message: God’s arm, his saving acts in history, especially deliverance from trouble.
- The Audience: Both “this generation” (living) and “everyone who is to come” (future). The witness is immediate and enduring.
- The Condition of Continued Life: He prays not to be forsaken, not to have his witness cut short. He wants to finish the task.

What the Commentators Say
7 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke observes that the speaker repeats the fact of old age and adds gray hair, a detail meant to strengthen his appeal. Though God already knows these things, He invites reasoning. When believers plead their case to Him, they are doing exactly what He commanded.
Barnes' Notes on the Bible Protestant 1832
Barnes stresses that the psalmist's plea for God's presence in old age is driven by a desire to pass accumulated wisdom to the rising generation. Unlike animals, which learn nothing from the past, humans build on experience, and the aged believer's ripe insight can still advance the world's knowledge and faith.
Calvin's Commentaries Reformed 1564
Calvin observes that this psalm closely follows Psalm 31, which David wrote during Saul's persecution. The distinctive feature is that David adapted the earlier prayer to his later crisis by adding references to his old age, showing how faith reuses past expressions of trust for new trials.
Cambridge Bible for Schools and Colleges Anglican 1880
This commentator highlights that the Hebrew word translated "strength" literally means "arm," a metaphor that suggests far more than raw power—it includes guidance, support, protection, and even conflict. He also notes that the verse likely refers to declaring God's might to the next generation, not the present one.
Geneva Bible Notes Reformed 1599
The Geneva note emphasizes that the psalmist does not ask for long life for its own sake, but for God to sustain him into old age so he can witness to God's power and strength. His plea is to be kept alive as long as he is useful for declaring God's works to the present generation and to those yet to come.
Gill's Exposition of the Bible Baptist 1748
Gill reads the psalmist's plea as a desire to continue revealing Christ through prophecy and Scripture. He identifies God's arm with the Messiah, who is God's power in creation and salvation, and sees the request to show God's strength as a petition to keep writing about Christ's work for all future generations.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry observes a sudden and dramatic shift in the psalmist's tone from fear to joyful praise, rooted entirely in faith and hope. He emphasizes the deliberate choice to hope continually in the darkest conditions, which then fuels an ever-increasing offering of praise to God.
