Moses' petition in Psalm 90:12 — "So teach us to number our days, that we may gain a heart of wisdom" — is a confession that fallen humanity is constitutionally unable to reckon rightly with its own mortality apart from divine instruction. Calvin observed that this numbering is not mere arithmetic but a Spirit-wrought apprehension of life's brevity that humbles pride and drives the soul toward God, while Matthew Henry noted that the prayer itself implies we are prone to forget our days and squander them as though time were inexhaustible. The "heart of wisdom" Moses seeks is not abstract knowledge but practical, covenant-oriented piety — a reordering of affections so that eternal things command the weight they deserve. Poole helpfully distinguished that to number our days is to live each one under the consciousness of judgment and eternity, spending ourselves in the fear of God rather than the pursuits of vanity. Taken together, the Reformed tradition reads this verse as both a rebuke of human self-sufficiency and an urgent summons to seek, through prayer and the Spirit's illumination, a life that counts what God counts — and thereby finds that brief days lived coram Deo are more fruitful than long years lived in forgetfulness of him.
Calvin (1560)
Psalm 90:11-13 11. Who knoweth the power of thy anger? and according to thy fear, so is thy wrath. 12. Teach us so [572] to number our days, and we shall apply our hearts to wisdom. 13. Return, O Jehovah! how long? Be pacified towards thy servants. 11. Who knoweth, the power of thy anger? Moses again returns to speak of the peculiar afflictions of the Israelites; for he had also on this occasion complained before of the common frailty and miseries of mankind. He justly exclaims that the power of God's wrath is immeasurably great. So long as God withholds his hand, men wantonly leap about like runaway slaves, who are no longer afraid at the sight of their master; nor can their rebellious nature be reduced to obedience in any other way than by his striking them with the fear of his judgment. The meaning then is, that whilst God hides himself, and, so to speak, dissembles his displeasure, men are inflated with pride, and rush upon sin with reckless impetuosity; but when they are compelled to feel how dreadful his wrath is, they forget their loftiness, and are reduced to nothing. What follows, According to thy fear, so is thy wrath, is commonly explained as denoting that the more a man is inspired with reverence towards God, the more severely and sternly is he commonly dealt with; for "judgment begins at the house of God," ( 1 Peter 4:17 .) Whilst he pampers the reprobate with the good things of this life, he wastes his chosen ones with continual troubles; and in short, "whom he loveth he chasteneth," ( Hebrews 12:6 .) It is then a true and profitable doctrine that he deals more roughly with those who serve him than with the reprobate. But Moses, I think, has here a different meaning, which is, that it is a holy awe of God, and that alone, which makes us truly and deeply feel his anger. We see that the reprobate, although they are severely punished, only chafe upon the bit, or kick against God, or become exasperated, or are stupified, as if they were hardened against all calamities; so far are they from being subdued. And though they are full of trouble, and cry aloud, yet the Divine anger does not so penetrate their hearts as to abate their pride and fierceness. The minds of the godly alone are wounded with the wrath of God; nor do they wait for his thunderbolts, to which the reprobate hold out their hard and iron necks, but they tremble the very moment when God moves only his little finger. This I consider to be the true meaning of the prophet. He had said that the human mind could not sufficiently comprehend the dreadfulness of the Divine wrath. And we see how, although God shakes heaven and earth, many notwithstanding, like the giants of old, treat this with derision, and are actuated by such brutish arrogance, that they despise him when he brandishes his bolts. But as the Psalmist is treating of a doctrine which properly belongs to true believers, he affirms that they have a strongly sensitive feeling of the wrath of God which makes them quietly submit themselves to his authority. Although to the wicked their own conscience is a tormentor which does not suffer them to enjoy repose, yet so far is this secret dread from teaching them to humble themselves, that it excites them to clamor against God with increasing frowardness. In short, the faithful alone are sensible of God's wrath; and being subdued by it, they acknowledge that they are nothing, and with true humility devote themselves wholly to Him. This is wisdom to which the reprobate cannot attain, because they cannot lay aside the pride with which they are inflated. They are not touched with the feeling of God's wrath, because they do not stand in awe of him. 12. Teach us so to number our days. Some translate to the number of our days, which gives the same sense. As Moses perceived that what he had hitherto taught is not comprehended by the understandings of men until God shine upon them by his Spirit, he now sets himself to prayer. It indeed seems at first sight absurd to pray that we may know the number of our years. What? since even the strongest scarcely reach the age of fourscore years, is there any difficulty in reckoning up so small a sum? Children learn numbers as soon as they begin to prattle; and we do not need a teacher in arithmetic to enable us to count the length of a hundred upon our fingers. So much the fouler and more shameful is our stupidity in never comprehending the short term of our life. Even he who is most skillful in arithmetic, and who can precisely and accurately understand and investigate millions of millions, is nevertheless unable to count fourscore years in his own life. It is surely a monstrous thing that men can measure all distances without themselves, that they know how many feet the moon is distant from the center of the earth, what space there is between the different planets; and, in short, that they can measure all the dimensions both of heaven and earth; while yet they cannot number threescore and ten years in their own case. It is therefore evident that Moses had good reason to beseech God for ability to perform what requires a wisdom which is very rare among mankind. The last clause of the verse is also worthy of special notice. By it he teaches us that we then truly apply our hearts to wisdom when we comprehend the shortness of human life. What can be a greater proof of madness than to ramble about without proposing to one's self any end? True believers alone, who know the difference between this transitory state and a blessed eternity, for which they were created, know what ought to be the aim of their life. No man then can regulate his life with a settled mind, but he who, knowing the end of it, that is to say death itself, is led to consider the great purpose of man's existence in this world, that he may aspire after the prize of the heavenly calling. 13. Return, O Jehovah! how long? After having spoken in the language of complaint, Moses adds a prayer, That God, who had not ceased for a long time severely to punish his people, would at length be inclined to deal gently with them. Although God daily gave them in many ways some taste of his love, yet their banishment from the land of promise was a very grievous affliction; for it admonished them that they were unworthy of that blessed inheritance which he had appointed for his children. They could not fail often to remember that dreadful oath which he had thundered out against them, "Surely they shall not see the land which I sware unto their fathers, neither shall any of them that provoked me see it: But as for you, your carcases, they shall fall in this wilderness," ( Numbers 14:23 , 32.) [573] Moses, no doubt, combines that sore bondage which they had suffered in Egypt with their wanderings in the wilderness; and therefore he justly bewails their protracted languishing in the words how long? As God is said to turn his back upon us, or to depart to a distance from us, when he withdraws the tokens of his favor, so by his return we are to understand the manifestation of his grace. The word nchm, nacham, which we have translated be pacified, signifies to repent, and may therefore not improperly be explained thus: Let it repent thee concerning thy servants. According to the not unfrequent and well known phraseology of Scripture, God is said to repent, when putting away men's sorrow, and affording new ground of gladness, he appears as it were to be changed. Those, however, seem to come nearer the mind of the Psalmist who translate, Comfort thyself over thy servants; for God, in cherishing us tenderly, takes no less pleasure in us than does a father in his own children. Now that is nothing else than to be pacified or propitious, as we have translated it, to make the meaning the more obvious. Footnotes: [572] Moses, as we learn from the passage to which Calvin refers, "was an hundred and twenty years old when he died, his eye was not dim, nor his natural force abated." He was eighty years old when God made him captain of the chosen people; and Aaron was eighty-three years old before he was made High Priest, Exodus 7:7 . These, and a few other similar cases, have led many to conclude that the age of eighty was not considered at that time the age of decrepitude; and consequently that this psalm, which limits the average length of human life to seventy or eighty years, must be of a later date than the time of Moses. But this is no valid argument against his being its penman. According to Calvin, seventy or eighty years was at that time, in general, the utmost limits of human life; and the longevity of Moses and some others who exceeded that limit was an exception to the general rule. If this should be called in question, it might be observed that this psalm treats of the afflictions and brevity of life, not in reference to all men absolutely, but with respect to the Israelites in particular, who, on account of their murmuring at the report of the spies who had been sent to spy out the land of Canaan, and other sins, provoked God to swear in his wrath that the carcases of all that were numbered of them according to their whole number, from twenty years old and upwards, with the exception of Caleb and Joshua, should fall in the wilderness during the forty years of their wandering in it, ( Numbers 14:27-29 .) Few of them, therefore, could have exceeded or even reached the age of fourscore years. It has been thought by some that at that time human life all over the world was reduced to the measure here specified, as its average standard. "The decree which abbreviated the life of man as a general rule to seventy or eighty years," observes Dr J. M. Good, "was given as a chastisement upon the whole race of Israelites in the wilderness. It does not appear that the term of life was lengthened afterwards. Samuel died about seventy years old, David under seventy-one, and Solomon under sixty; and the history of the world shows that the abbreviation of life in other countries was nearly in the same proportion." [573] "There is an ambiguity in kn, as it denotes either so or rightly Hence the interpretation is twofold; either so make us to know that we may cause a heart of wisdom to come,' i e., so instruct us that we may acquire a wise heart. Or, teach us to number our days rightly,' etc. LXX. give it another and distorted interpretation." -- Bythner
Geneva Bible Notes (1599)
So teach us to number our days, that we may apply our hearts unto {l} wisdom. (l) Which is by considering the shortness of our life, and by meditating the heavenly joys.
John Trapp (1647)
So teach [us] to number our days, that we may apply [our] hearts unto wisdom. So teach us to number our days — The philosopher affirms, that man is therefore the wisest of creatures, because he alone can number, Bruta non numerant. But in this divine arithmetic of numbering our days (to the which all other is not to be compared, no, though we could, as Archimedes boasted, number the stars of heaven, or the sands by the sea shore), God himself must be our teacher, or we shall never do it to purpose. R. Solomon observeth, that the word ëï rendered "so" here, if taken as numeral letters, maketh seventy, and the years of our life are seventy; out of which, say other Rabbis, if we deduct the time of childhood and youth, which is vanity, the time of sleep, repose, repast, and recreation (which is more than the one half), and the time of affliction and grief which we enjoy not, what a poor pittance will life be reduced unto! That we may apply our hearts — Heb. that we may cause them to come; for naturally they hang off, and make strange. Unto wisdom — To the true fear of God, and mortification of sin, which is the sting of death, and makes it a trap door to hell. This is hard to do, but must be done; or men are undone for ever. To live with dying thoughts is the way to die with living comforts.
Matthew Poole (1685)
So teach us, by thy Spirit and grace, as thou hast already taught us by thy word. Or, teach us rightly (as this word is used, Numbers 27:7 2 Kings 7:9 ) to number, & c., as it follows. To number our days ; to consider the shortness and miseries of this life, and the certainty and speediness of death, and the causes and consequences thereof. That we may apply our hearts unto wisdom; that we may heartily devote ourselves to the study and practice of true wisdom, which is nothing else but piety, or the fear of God. And why so? Not that the Israelites might thereby procure a revocation of that peremptory sentence of death passed upon all that generation; nor that other men might hereby prevent their death, both which he very well knew to be impossible; but that men might arm and prepare themselves for death, and for their great account after death, and might make sure of the happiness of the future life; of which this text is a plain and pregnant proof.
John Gill (1748)
So teach us to number our days,.... Not merely to count them, how many they are, in an arithmetical way; there is no need of divine teachings for that; some few instructions from an arithmetician, and a moderate skill in arithmetic, will enable persons not only to count the years of their lives, but even how many days they have lived: nor is this to be understood of calculating or reckoning of time to come; no man can count the number of days he has to live; the number of his days, months, and years, is with the Lord; but is hid from him: the living know they shall die; but know not how long they shall live, and when they shall die: this the Lord teaches not, nor should we be solicitous to know: but rather the meaning of the petition is, that God would teach us to number our days, as if the present one was the last; for we cannot boast of tomorrow; we know not but this day, or night, our souls may be required of us: but the sense is, that God would teach us seriously to meditate on, and consider of, the shortness of our days; that they are but as a shadow, and there is no abiding; and the vanity and sinfulness of them, that so we may not desire to live here always; and the troubles and sorrows of them, which may serve to wean us from the world, and to observe how unprofitably we have spent them; which may put us upon redeeming time, and also to take notice of the goodness of God, that has followed us all our days, which may lead us to repentance, and engage us in the fear of God: that we may apply our hearts unto wisdom; to consider our latter end, and what will become of us hereafter; which is a branch of wisdom so to do; to seek the way of salvation by Christ; to seek to Christ, the wisdom of God, for it; to fear the Lord, which is the beginning of wisdom; and to walk circumspectly, not as fools, but as wise; to all which an application of the heart is necessary; for wisdom is to be sought for heartily, and with the whole heart: and to this divine teachings are requisite, as well as to number our days; for unless a man is taught of God, and by his Spirit convinced of sin, righteousness, and judgment, he will never be concerned, in good earnest, about a future state; nor inquire the way of salvation, nor heartily apply to Christ for it: he may number his days, and consider the shortness of them, and apply his heart to folly, and not wisdom; see Isaiah 22:21 .
Matthew Henry (1714)
Those who would learn true wisdom, must pray for Divine instruction, must beg to be taught by the Holy Spirit; and for comfort and joy in the returns of God's favour. They pray for the mercy of God, for they pretend not to plead any merit of their own. His favour would be a full fountain of future joys. It would be a sufficient balance to former griefs. Let the grace of God in us produce the light of good works. And let Divine consolations put gladness into our hearts, and a lustre upon our countenances. The work of our hands, establish thou it; and, in order to that, establish us in it. Instead of wasting our precious, fleeting days in pursuing fancies, which leave the possessors for ever poor, let us seek the forgiveness of sins, and an inheritance in heaven. Let us pray that the work of the Holy Spirit may appear in converting our hearts, and that the beauty of holiness may be seen in our conduct.
Jamieson-Fausset-Brown
12. This he prays we may know or understand, so as properly to number or appreciate the shortness of our days, that we may be wise.
Barnes (1832)
So teach us to number our days - literally, "To number our days make us know, and we will bring a heart of wisdom." The prayer is, that God would instruct us to estimate our days aright: their number; the rapidity with which they pass away; the liability to be cut down; the certainty that they must soon come to an end; their bearing on the future state of being. That we may apply our hearts unto wisdom - Margin, "Cause to come." We will bring, or cause to come, a heart of wisdom. By taking a just account of life, that we may bring to it a heart truly wise, or act wisely in view of these facts. The prayer is, that God would enable us to form such an estimate of life, that we shall be truly wise; that we may be able to act "as if" we saw the whole of life, or as we should do if we saw its end. God sees the end - the time, the manner, the circumstances in which life will close; and although he has wisely hidden that from us, yet he can enable us to act as if we saw it for ourselves; to have the same objects before us, and to make as much of life, "as if" we saw when and how it would close. If anyone knew when, and where, and how he was to die, it might be presumed that this would exert an important influence on him in forming his plans, and on his general manner of life. The prayer is, that God would enable us to act "as if" we had such a view.
