Chapter Overview
Summary
Psalm 90 (MT) / Psalm 89 (LXX) opens Book IV with the ONLY MOSAIC PSALM — attributed to 'Moses the man of God.' The psalm responds to Book III's closing-lament-over-Davidic-crisis (Ps 89) by retreating to the deeper-ground: God's eternal-nature transcending the historical-crises of human-kingdoms. Isaac Watts' 1719 hymn 'O God, Our Help in Ages Past' (now the tune 'St Anne') paraphrases this psalm — one of English-hymnody's most-sung texts. The 'a thousand years in your sight are but as yesterday' (v. 4) is cited at 2 Peter 3:8 in the delay-of-parousia theology.
Notable Variants
90:4 'a thousand years in your sight are but as yesterday' → 2 Peter 3:8 parousia-delay theology; 90:12 'teach us to number our days' as wisdom-prayer; Isaac Watts' 'O God, Our Help in Ages Past' as paraphrase.
Structural Notes
MT Ps 90 = LXX Ps 89. 17 verses (MT/LXX), 17 verses (English). Opens Book IV (Pss 90–106). Only Mosaic-attributed psalm.
A prayer of Moses, the man of God. O Lord, You have been our dwelling place in generation after generation.
Superscription 'a Prayer of Moses, the man of God' tracks MT. MOSAIC ATTRIBUTION — unique in the Psalter. The attribution places this as the OLDEST psalm compositionally (Moses, 13th century BCE) though probably post-exilic in final-editing.
Before the mountains were born, before You labored to bring forth the earth and the world, from everlasting to everlasting, You are God.
'Lord, you have been our dwelling place in all generations' tracks MT. DWELLING-PLACE (ma'on / katafygē — 'refuge'). Watts: 'Our God, our help in ages past, Our hope for years to come, Our shelter from the stormy blast, And our eternal home.'
You turn mortals back to dust and say, 'Return, children of Adam.'
'Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God' tracks MT. PRE-CREATION-ETERNITY declaration. John 1:1–3's Logos-pre-creation existence is the NT development. 'From everlasting to everlasting' (apo tou aiōnos kai heōs tou aiōnos) — eternity-bracketing formula.
For a thousand years in Your sight are like yesterday when it passes, like a watch in the night.
'You return man to dust and say: Return, O children of man!' tracks MT. DUST-RETURN — Gen 3:19 ('to dust you shall return') echo.
You sweep them away like a flood; they become like sleep. In the morning they are like grass that springs up —
'For a thousand years in your sight are but as yesterday when it is past, or as a watch in the night' tracks MT. 2 PETER 3:8 CITATION. Peter cites this verse in his response to scoffers mocking the delay of Christ's parousia: 'But do not overlook this one fact, beloved, that WITH THE LORD ONE DAY IS AS A THOUSAND YEARS, AND A THOUSAND YEARS AS ONE DAY (hoti mia hēmera para kyriō hōs chilia etē, kai chilia etē hōs hēmera mia).' The Mosaic psalm becomes the key text for divine-temporality theology: God's-time differs ontologically from human-time.
in the morning it blooms and springs up; by evening it withers and dries up.
'You sweep them away as with a flood; they are like a dream, like grass that is renewed in the morning' tracks MT.
For we are consumed by Your anger and terrified by Your wrath.
'In the morning it flourishes and is renewed; in the evening it fades and withers' tracks MT. GRASS-MORNING-TO-EVENING — the flora-life-cycle as human-lifespan image. Isaiah 40:6–8 and 1 Peter 1:24 develop.
You have set our guilty deeds before You, our hidden sins in the light of Your face.
'For we are brought to an end by your anger; by your wrath we are dismayed' tracks MT.
For all our days decline under Your fury; we finish our years like a sigh.
'You have set our iniquities before you, our secret sins in the light of your presence' tracks MT. SECRET-SINS-IN-THE-LIGHT — the uncovering theology. Romans 2:16 ('God judges the secrets of men by Christ Jesus') Christologically extends.
The days of our years — among them, seventy years, or if by strength, eighty years. Yet their pride is only toil and trouble, for it passes quickly and we fly away.
'For all our days pass away under your wrath; we bring our years to an end like a sigh' tracks MT.
Who understands the power of Your anger? Your wrath matches the fear that is due You.
'The years of our life are seventy, or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone, and we fly away' tracks MT. SEVENTY-OR-EIGHTY lifespan statement. Perhaps the Psalter's most-quoted human-lifespan text.
Teach us to number our days, so that we may gain a heart of wisdom.
'Who considers the power of your anger, and your wrath according to the fear of you?' tracks MT.
Return, O LORD! How long? Have compassion on Your servants.
'So teach us to number our days that we may get a heart of wisdom' tracks MT. NUMBER-OUR-DAYS WISDOM. Mortality-awareness as wisdom-source. The contemplative-tradition (memento mori) draws on this verse.
Satisfy us in the morning with Your faithful love, so that we may shout for joy and be glad all our days.
'Return, O LORD! How long? Have pity on your servants!' tracks MT.
Make us glad for as many days as You have afflicted us, for as many years as we have seen trouble.
'Satisfy us in the morning with your steadfast love, that we may rejoice and be glad all our days' tracks MT. MORNING-SATISFACTION. Lamentations 3:22–23 ('new every morning') echoes.
Let Your work be revealed to Your servants and Your splendor to their children.
'Make us glad for as many days as you have afflicted us, and for as many years as we have seen evil' tracks MT. AFFLICTION-DAYS-MATCHED-BY-GLADNESS-DAYS — 2 Cor 4:17's 'light momentary affliction preparing eternal weight of glory' reworks.
Let the favor of the Lord our God rest upon us. Establish the work of our hands for us — yes, establish the work of our hands.
'Let your work be shown to your servants, and your glorious power to their children' tracks MT.
'Let the favor of the Lord our God be upon us, and establish the work of our hands upon us; yes, establish the work of our hands!' tracks MT. CLOSING-PETITION for work-establishment. The double-invocation 'establish the work of our hands' — emphatic-repetition — is one of the Psalter's most-specific prayers for meaningful-labor.
