Psalms 90

BOOK 4

A Prayer by Moses, the man of God.

Lord, you have been our dwelling place for all generations.

Before the mountains were born, before you had formed the earth and the world, even from everlasting to everlasting, you are God.

You turn man to destruction, saying, “Return, you children of men.”

For a thousand years in your sight are just like yesterday when it is past, like a watch in the night.

You sweep them away as they sleep. In the morning they sprout like new grass.

In the morning it sprouts and springs up. By evening, it is withered and dry.

For we are consumed in your anger. We are troubled in your wrath.

You have set our iniquities before you, our secret sins in the light of your presence.

For all our days have passed away in your wrath. We bring our years to an end as a sigh.

The days of our years are seventy, or even by reason of strength eighty years; yet their pride is but labor and sorrow, for it passes quickly, and we fly away.

Who knows the power of your anger, your wrath according to the fear that is due to you?

So teach us to count our days, that we may gain a heart of wisdom.

Relent, LORD! How long? Have compassion on your servants!

Satisfy us in the morning with your loving kindness, that we may rejoice and be glad all our days.

Make us glad for as many days as you have afflicted us, for as many years as we have seen evil.

Let your work appear to your servants, your glory to their children.

Let the favor of the Lord our God be on us. Establish the work of our hands for us. Yes, establish the work of our hands.

Overview.
This psalm, attributed to Moses, reflects on the eternal nature of God and the brevity and frailty of human life under divine judgment, while also pleading for God’s mercy, restoration, and the confirmation of His redemptive work. It stands as a profound meditation on divine permanence and human transience, calling for wisdom in light of mortality and for God’s favor to renew and establish His people. Positioned early in Book IV of the Psalter (Psalms 90–106), this chapter shifts the tone from earlier praises and laments, grounding worship in holy reverence for God’s sovereignty.

Flow.

The psalm opens with a declaration of God as the eternal dwelling place of His people, establishing His timeless existence before all creation (v. 1–2).
It moves to depict human mortality as divinely ordained, with life fleeting as grass and days short and full of toil, set under the weight of divine wrath for sin (v. 3–11).
Then comes a turning point: a plea for God to relent, to show compassion, and to teach His people to number their days for the sake of wisdom (v. 12–13).
The psalm closes with petitions for satisfaction in God’s steadfast love, joy in place of affliction, and the enduring blessing of God’s glory and favor upon His people’s work (v. 14–17).

Connections.
Following Psalm 89, which ends with the anguished question of delayed deliverance and a seemingly broken covenant, Psalm 90 deepens the contemplation of God’s ways in light of human suffering and divine eternity. Where Psalm 89 wrestles with the apparent failure of Davidic promises, Psalm 90 moves to a more primal truth—God’s eternal reign and the moral order of His rule—preparing the way for Psalm 91, which responds with trust in God’s protective care. This chapter sets a theological foundation of divine sovereignty and human limitation that frames the subsequent affirmations of safety and salvation.

What it teaches.
The psalm affirms God’s self-existence and eternity, standing apart from and over all creation (WCF 2.1; HC LD 9), and His holy justice, which rightly condemns human sin (WCF 19.6; BC Art. 15). It acknowledges the pervasiveness of sin and its consequences under divine wrath (WCF 6.3; HC LD 2), while also calling for wisdom that comes from reverent dependence on God (WCF 1.6; HC LD 7). The plea for God to satisfy, restore, and establish the work of His people points forward to the redemptive grace and renewal only possible through His covenant faithfulness (WCF 7.1; LD 1).

Apply.
Number your days in dependence on God’s mercy, so that your work bears lasting good through His establishing grace.
