Cry for Divine Intervention and Vow of Public Thanksgiving
17Lord, how long will you look on? Rescue my soul from their destruction, my precious life from the lions.18I will give you thanks in the great assembly. I will praise you among many people.
Psalms 35:17–18 presents a psalmist crying out to God with urgent desperation while simultaneously pledging future thanksgiving in the assembly. The passage moves from a complaint about God's apparent inaction amid persecution to a vow to publicly praise God, expressing both honest lament and confidence in divine deliverance.
The same breath that cries "How long, Lord?" is the one that vows to praise him—faith lives not in resolved answers but in covenantal honesty held together with stubborn trust.
Catholic tradition illuminates these verses at several interlocking levels.
The Theology of Lament as Faith. The Catechism teaches that prayer is a covenant relationship, a "vital and personal relationship with the living and true God" (CCC 2558). The "how long?" of verse 17 is not a failure of faith but its exercise under trial. St. Augustine, in his Enarrationes in Psalmos, insists that Christ himself prays in the Psalms, and that when we cry "how long?" we join our voice to his. The Church therefore does not suppress lament; she canonizes it in the Liturgy of the Hours.
Todah and the Eucharist. Catholic biblical scholarship (notably following the work of Hartmut Gese and its reception by Pope Benedict XVI in The Spirit of the Liturgy) has traced the todah — the thanksgiving sacrifice — as the liturgical forerunner of the Eucharist. The psalmist's vow to give thanks in the great assembly is structurally the same movement as the Mass: suffering and petition answered by communal, sacrificial praise. The "great assembly" (qahal) becomes, in the New Covenant, the ekklēsia — the Church — in whom and through whom Christ eternally offers his todah to the Father.
The Communion of Suffering and Praise. Vatican II's Sacrosanctum Concilium (§83–84) teaches that in the Liturgy of the Hours the whole Church "joins Christ in his prayer." These two verses thus encode the entire arc of Christian liturgical spirituality: honest suffering brought before God, and the confident, public praise that the covenant makes possible even before the answer arrives.
Contemporary Catholics often feel pressure to suppress lament — to perform spiritual contentment rather than bring raw grievance before God. Verses 17–18 offer a corrective and a model. When a diagnosis is prolonged, a prayer seems unanswered, or an injustice goes unremedied, the instinct to cry "how long, Lord?" is not a symptom of weak faith but an expression of covenantal boldness. God can bear our frustration; what he calls us away from is silent despair or bitter abandonment of prayer altogether.
The immediate pivot to a vow of public thanksgiving in verse 18 is equally practical: the psalmist binds himself, in advance, to communal worship. For Catholics, this looks like committing to Sunday Mass even in seasons of spiritual dryness — not because feelings have resolved, but because the "great assembly" is where God answers. The Eucharist is the space where the "how long?" of verse 17 is met with the "here I am" of the risen Christ. Concretely: bring your specific unanswered prayer to Mass this Sunday, name it at the Offertory, and let the Canon's great prayer of thanksgiving carry it before the Father alongside Christ's own.
Commentary
Psalms 35:17 — "Lord, how long will you look on?"
The Hebrew verb translated "look on" (ra'ah, רָאָה) carries the nuance of beholding something passively, almost as a spectator. The psalmist, surrounded by false accusers and violent enemies (see vv. 1–16), accuses God — with reverent boldness — of watching the injustice unfold without intervening. This is not impiety but a deeply covenantal mode of address: because God has promised to be Israel's defender (cf. Deut 32:35–36), his apparent inaction demands an explanation. The phrase "how long" (עַד־מָה, ʿad-mah) is one of the defining cries of the Psalter (cf. Pss 6:3; 13:1–2; 74:10; 79:5; 90:13), functioning as a liturgical shorthand for the community's experience of God's felt absence. It is not a denial of God's existence but a paradoxical form of faith — one can only cry "how long" to a God one still believes is present and capable of acting.
The verse continues (in the fuller Hebrew text): "rescue my soul from their ravages, my precious life from the lions." The image of lions (כְּפִירִים, kephirim — young, fierce lions) intensifies the sense of mortal danger and helplessness. The psalmist's "soul" (nephesh) and "precious life" (יְחִידָתִי, yechidati — literally "my only one," suggesting something irreplaceable, unique) are at stake. This word yechidati is used elsewhere for an only child (cf. Gen 22:2, of Isaac), giving the verse a poignant vulnerability: the psalmist holds out before God what is most singular and beloved about his own existence. The cry is not abstract; it is intimate and urgent.
Psalms 35:18 — "I will give you thanks in the great assembly"
The abrupt shift to a vow of thanksgiving (todah, תּוֹדָה) is characteristic of the individual lament psalm. The psalmist does not wait for deliverance to praise — he pledges praise in advance, staking his future worship on the certainty of God's faithfulness. The "great assembly" (בְּקָהָל רָב, beqahal rav) and the phrase that follows in the full Hebrew — "among a numerous people I will praise you" — situate this act of worship in the liturgical gathering of Israel. Private suffering is to be answered by public praise. This is theologically significant: the individual's rescue becomes communal testimony. The "great assembly" (qahal) is the technical term for the solemn cultic gathering of God's people before the LORD, foreshadowing the Church's Eucharistic assembly.
Typological and Spiritual Senses
The Church Fathers, following the Christological reading of the Psalter established by Christ himself (cf. Luke 24:44), read Psalm 35 as spoken in the voice of Christ in his passion. Verse 17's "how long will you look on?" resonates powerfully with the cry of dereliction from the cross (Matt 27:46 // Ps 22:1). Christ, the truly innocent one, endured the silence of the Father while his enemies gloated — making this verse not merely a human complaint but the prayer of the incarnate Son in his most abandoned hour. Verse 18's vow of thanksgiving in the great assembly finds its fulfilment in the Resurrection: the risen Christ, who is "not ashamed to call them brethren," proclaims the Father's name "in the midst of the assembly" (Heb 2:11–12, quoting Ps 22:22 in a parallel structure). The todah-vow of the psalmist is perfectly realized in Christ's Eucharistic self-offering — the word "Eucharist" itself derives from the Greek eucharistia, thanksgiving — offered in and through the Church, the true "great assembly."
