A line printed on planners and read at funerals. In its setting it is a hard, honest prayer that ends asking God to make our work last.
Teach us to number our days is Psalm 90:12, a prayer asking God to help us see how short life is so that we live it wisely. Counting the days is the means. A heart of wisdom is the goal.
It is not a countdown and it is not a promise of a set lifespan. It is a request to be taught, prayed by people who had felt the full weight of their frailty, and the psalm finishes by asking God to establish the work of their hands.
The psalm does not stop at “life is short.” It keeps going until “so make what we do with it hold.”
Lord, you have been our dwelling place throughout all generations. The psalm starts with God before it says a word about us.
A thousand years are like yesterday to God, and a human life is like grass, new in the morning and dry by evening.
The psalmist reads his people's suffering as God's anger. Most devotionals skip this part, and it is where the seventy years line sits.
Teach us to number our days. After all that honesty, the prayer turns from complaint to request.
Have compassion. Satisfy us in the morning. Establish the work of our hands.
Psalm 90 opens Book Four of the Psalter, and it is the only psalm with Moses' name over it. The heading reads, “A prayer of Moses the man of God.”
We should be honest about that heading. The superscriptions reflect how Israel's editors and later tradition understood each poem, and many scholars date this one well after the wilderness. The heading does not settle authorship. It is old tradition, and it tells us how Israel wanted this prayer read.
There is a reason the tradition landed on Moses. Andrew Davis of Hebrew College points out that verse 13 uses the same verbs Moses used when he interceded after the golden calf in Exodus 32:12, turn and relent. Davis also warns against softening it: Psalm 90 is “not a leisurely meditation on mortality but a desperate cry for help.”
Psalm 89 ends mourning a broken throne, and Book Four answers by reaching back behind the kings to Moses. Whoever wrote it, the psalm prays the way Moses prayed. For the man behind the tradition, see who Moses was, and for the collection as a whole, who wrote the Psalms.
“A thousand years in your sight are like a day that has just gone by, or like a watch in the night.”
Psalm 90:4A thousand years pass for God like yesterday already gone, or like one watch of the night, a few hours a guard stands through and barely remembers. Then verses 5 and 6 turn to us: grass, new in the morning and withered by evening.
The point is not that God is distant. He is the one fixed thing, and we are not. That is why verse 1 comes first. The only safe place for grass is in the presence of the One who does not wither.
Centuries later Peter borrowed this verse. In 2 Peter 3:8 he writes, “With the Lord a day is like a thousand years, and a thousand years are like a day.” He was answering scoffers in his own generation who asked where the promised coming was. God is not slow, he said. He is patient.
One day equals a thousand years. Use it to build prophetic calendars or stretch Peter's warning across millennia.
Steadying a first-century church with a psalm. The day of the Lord he described came on their generation, closing the old covenant age in AD 70.
Neither the psalm nor Peter hands us a conversion rate. Peter used poetry about how God sees time to say that a wait of a few decades was mercy, not failure. More on the day of the Lord and how it landed in the first century.
Verse 12 is the hinge. After eleven verses of dust, grass and anger, the prayer does not say, so let us eat and drink. It says, teach us.
“Teach us to number our days, that we may gain a heart of wisdom.”
Psalm 90:12From the verb manah, to count or number. An ordinary word, not a mystical one.
Our days. Plural and personal. Not the ages of history, but the ordinary days a person actually lives.
The heart. Davis notes that “the heart in ancient Israel was the seat of the will and intellect rather than emotion.” A wise heart is a well-ordered mind and will.
Wisdom. In the Hebrew Bible this is practical skill for living, the kind that shows up in how you speak, work, spend and treat people.
So the request is plain. Help us count honestly, so that we think and choose well. Not a morbid fixation on death, just seeing the real size of what we have been given.
Proverbs says this wisdom begins with the fear of the Lord, and that beginning is reverence, not terror. See also how wisdom and understanding go hand in hand.
You do not number your days by tracking them. You number them by letting their shortness change what you do with the next one.

Manage My Giving"Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver."2 Corinthians 9:7
“Our days may come to seventy years, or eighty, if our strength endures; yet the best of them are but trouble and sorrow, for they quickly pass, and we fly away.”
Psalm 90:10This verse gets quoted as though God guaranteed everyone seventy years, and some teachers tell people to claim it by faith. Read it again. It is a lament.
Psalm 90:10 is a description, not a promise. The psalmist is naming how short and hard life feels, using round numbers that meant a long life in the ancient world. He is not setting a floor under anybody's lifespan.
The strongest other view points to real promises, like Psalm 91:16 or the long life attached to honoring your parents. They describe the general blessing of a wise life, the way Proverbs does. None is a contract with a number on it.
The tradition behind the heading even carries its own correction. Deuteronomy 34:7 says Moses died at a hundred and twenty. We have covered how old Moses was when he died elsewhere.
Here is why it matters. When 90:10 is taught as a promise, every early death becomes a question mark over somebody's faith, and grieving families get told, quietly or out loud, that they failed to claim what was theirs. That teaching is wrong, and it is cruel. An early death is not a verdict on anyone's faith, and it is not God taking the person.
We refuse the opposite error too. The psalm never says life is pointless because it is short. It says ask God for wisdom and for work that lasts.
What is Psalm 90:10 actually doing?
The next words are “yet the best of them are but trouble and sorrow.” It is a lament, and the tradition behind the heading has Moses himself living to a hundred and twenty.
The psalmist felt death as God's anger: “We are consumed by your anger and terrified by your indignation.” That was his real experience, and Scripture keeps it on the record.
But we read every part of the Bible through Jesus, and Jesus treats death as an enemy, not God's instrument. He weeps at a friend's tomb and then calls him out of it. Hebrews says He came to “free those who all their lives were held in slavery by their fear of death.”
“The last enemy to be destroyed is death.”
1 Corinthians 15:26Dust and grass, felt as wrath. Honest, and incomplete.
The Father's heart is life. Death is what He came to undo, not a tool He uses.
Eternal life is given in Christ, and it starts now. See what eternal life is.
The psalm begs God to return in compassion. In Jesus He did, and the answer is resurrection.
Maybe you are reading this after hard news, beside a hospital bed, or weeks after a funeral. You do not need a lecture on wisdom. You need to know that God did not do this to you, and that He is near.
Psalm 90 gives you permission to say how heavy it is. You can pray its hard middle out loud. If this season feels like the valley of the shadow of death, you are not walking it alone.
Please do not carry it by yourself. Lean on the people around you and let us pray with you through our prayer page.
“May the favor of the Lord our God rest on us; establish the work of our hands for us, yes, establish the work of our hands.”
Psalm 90:17The psalm could have ended at verse 12. Instead it asks for more. Relent. Satisfy us in the morning. Make us glad for as many days as we have seen trouble. And then, twice, establish the work of our hands.
Grass lives still want to leave something that holds. The psalmist does not call that wish vanity. He asks God to make it firm.
In Christ the prayer has an answer. Paul told the Corinthians their “labor in the Lord is not in vain.” What is done in love, in the Kingdom that is here now, is not swept away with the grass.
Verse 14 asks to be satisfied in the morning with God's unfailing love. Before the phone, a few quiet minutes to receive that.
People, generosity, the Kingdom work in front of you. Jesus called it storing up treasure in heaven, and it is a way of living today.
Ask God to establish your job, your parenting, the small ministry nobody sees. That is not selfish. It is Psalm 90.
The psalm is plural from start to finish. If you are on Long Island, come see us in Deer Park.
Psalm 90 is honest about dust. But it begins with God as our dwelling place and ends asking Him to make our work last, and that frame is the point.
Jesus closes the frame. He is the dwelling place of verse 1 come among us, the compassion verse 13 begged for. In Him death is a defeated enemy, and the days we count are lived inside eternal life.
So number your days. Not in fear and not with a stopwatch. Count them the way you count something precious, so you do not waste it.
For related reading, see what wisdom means in the Bible, God's plan for your life, what the Kingdom of God is and what happens when we die.
Psalm 90 sets our grass-short lives against an everlasting God, asks Him to teach us to count our days for a wise heart, never promises seventy years, and ends asking Him to establish our work, which in Jesus He does.
A diagnosis, a loss, a season that feels too short. You do not have to pray it alone. Send us your request and someone at Sound of Heaven will pray with you.
It is Psalm 90:12, a prayer asking God to help us see how short life is so we can live it wisely. The Hebrew verb means to count. The goal is stated in the second half of the verse, that we may gain a heart of wisdom, and in ancient Israel the heart was the seat of thinking and choosing. It is not a countdown, and it is not a promise about how long anyone will live.
The heading calls it a prayer of Moses the man of God, and it is the only psalm with his name on it. Headings like this reflect the tradition of Israel's editors rather than a signature, and many scholars date the psalm later, so we hold it as old tradition and say so honestly. Verse 13 echoes the words Moses used when he interceded for Israel in Exodus 32:12. Either way, the psalm prays the way Moses prayed.
No. The verse says our days may come to seventy years, or eighty if our strength endures, and then says the best of them are trouble and sorrow and quickly pass. It is a lament about how short life is, using round numbers for a long life in the ancient world. Teaching it as a promise leaves grieving families wondering whether they lacked faith, and an early death is never a verdict on anyone's faith.
Psalm 90:4 says a thousand years in God's sight are like a day that has just gone by, or a watch in the night. Peter borrowed the line in 2 Peter 3:8 to answer scoffers in the first century, saying God was not slow but patient. It is poetry about God's perspective on time, not a formula for converting days into millennia or building prophetic calendars.
It is the closing request of Psalm 90, repeated twice in verse 17. After admitting that human life is as brief as grass, the psalmist asks God to make what His people do firm and lasting. In Christ it has an answer. Paul told the Corinthians that their labor in the Lord is not in vain, because what is done in love within the Kingdom is not lost.
