Scholars' Consensus
Commentators across traditions agree that Ecclesiastes 6:12 is a climactic statement of human limitation. The Preacher poses two rhetorical questions, 'who knows what is good for man?' and 'who can tell what will be after him?', to underscore that no one can discern their true good or the future. Adam Clarke observes that what we deem good often proves evil, and what we think evil often proves good; our ignorance makes it hazardous to choose. The Cambridge Bible notes the echo of Pyrrhonian skepticism in the 'who knows?' formula. Gill emphasizes that because life is brief like a shadow, we cannot determine what is best. Keil and Delitzsch argue that to know what is good for someone, you would need to penetrate the future, but we are 'poor simpletons' confined to the present. The consensus is clear: only God knows. Human wisdom, however earnest, cannot decide what is truly beneficial, nor can it penetrate what lies ahead. The verse closes the section by leaving the reader with a question, not an answer.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Skeptical reading: The Cambridge Bible connects the 'who knows?' formula to Pyrrhonian skepticism, suggesting the Preacher denies any possibility of knowledge about the good.
- Wisdom reading: Gill, Clarke, and Matthew Henry see the verse as urging contentment and trust in God, with 'good' defined by God's will rather than human speculation.
- Pessimistic reading: Some modern readers interpret the verse as expressing existential despair, where no answer is possible—only the stark reality of ignorance and death.
What is clear: All sides agree that human beings cannot know what is truly good for themselves or what will happen after they die; only God possesses that knowledge.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of 'good' | All traditions agree the verse denies human ability to know what is genuinely beneficial in life. | Some (classical Protestant commentaries) focus on 'good' as practical well-being (health, wealth, relationships). Others see it as the supreme good or moral perfection, which only God can define. The Jewish Targum identifies it with study of the Law. |
| Purpose of the questions | The questions are rhetorical, not genuine inquiries; they highlight limits of human knowledge. | The Cambridge Bible sees the phrase 'who knows?' as a formula of Pyrrhonian skepticism. Others (Gill, Clarke) read it as a practical warning to be content with what God gives, not as a philosophical position. |
| Response to ignorance | The verse leads toward humility before God rather than despair. | Some (Matthew Henry) emphasize that we should pray for wisdom. Others (Barnes) highlight God's sovereignty as the only comfort. A minority (Wesley) stress the fleeting nature of life, urging preparation for eternity. |
Historical & Cultural Context
Ecclesiastes belongs to the wisdom literature of the Old Testament, traditionally attributed to Solomon but likely composed in the post-exilic period. The author calls himself Qoheleth, 'the Preacher' or 'the Assembler,' and writes from a perspective of profound realism about life 'under the sun', that is, life seen from a purely human, horizontal vantage point, without divine revelation.
The phrase 'who knows?' appears elsewhere in the Old Testament as a genuine question (Psalm 4:6, 'Who will show us any good?') but in Ecclesiastes it becomes a rhetorical device underscoring the limits of human perception. The Preacher's world is one where the righteous suffer and the wicked prosper, where wisdom cannot guarantee success, and where death levels all. The shadow metaphor (tsel) is common in ancient Near Eastern texts: in Job 8:9 and 14:2, in Psalm 144:4, and in 1 Chronicles 29:15, life is a fleeting shadow. The word 'number' (mispar) in the verse emphasizes that our days are countable, few, measurable, and soon gone.
Some scholars, like those behind the Cambridge Bible, detect the influence of Greek skepticism (Pyrrhonism) here, but the core theme is thoroughly biblical: human beings cannot know the future, and even the present eludes their grasp. The 'good' (tov) may refer to practical well-being or the classical summum bonum; Qoheleth argues that no one can define it with certainty. The verse serves as a caution against pride in planning and as an invitation to humility before God.
Textual Notes
The Hebrew text of Ecclesiastes 6:12 is stable across the major manuscripts (MT, LXX, Syriac, Targum). The consulted sources note no significant variants. The phrase ya'asem katsel ('he spends them like a shadow') has a singular suffix on the verb ('them') referring to 'days,' which is grammatically consistent. Variations in English translations reflect different ways of handling the Hebrew syntax (especially the relative clause with asher), but the underlying text is not in dispute.
Reception History
The Targum and Midrash (cited by Gill) interpret the verse as an encouragement to study the Law, which they identify as the only certain good. In Christian tradition, Ecclesiastes 6:12 has often been used in meditations on the brevity of life and the vanity of worldly pursuits. Gregory of Nyssa referred to the shadow image when discussing human frailty. The verse appears in funeral liturgies and as a motto for humility in the face of Providence. John Wesley used it to argue that we cannot know what is best for us, so we must trust God's ordering. In modern times, the existentialist undertones have drawn attention from thinkers like Peter Kreeft, who sees Qoheleth as a precursor to the honest skeptic who finds rest only in God.
Preaching This Verse
Three-point outline
- We do not know what is truly good. Our judgments about what benefits us are clouded by limited perspective and self-deception. Adam Clarke observed that we often mistake evil for good and good for evil.
- Life is fleeting. The Preacher uses the phrase 'like a shadow', quickly gone, insubstantial. This brevity makes the search for a permanent good urgent but elusive.
- The future is hidden. We cannot 'tell a man what will be after him.' Neither wealth, reputation, nor family legacy can be secured; we entrust it all to God.
Five-point outline
- The rhetorical question. 'Who knows?' is not a request for information but a declaration that no one can answer. It sets the tone of humility.
- The content of 'good.' Is it health, wealth, long life? The Preacher has shown each is unreliable. True good is inseparable from the fear of God (Ecclesiastes 12:13).
- The shadow life. Life is described as 'vain' (hebel) and as a shadow, temporary, dependent, unable to stand on its own.
- The mysterious future. 'After him' refers to what happens on earth after a person dies. We cannot control or even know whether our labour will be wasted.
- The call to trust. If we cannot know the future, we are freed to trust the One who does. The Preacher does not leave us in despair but points toward God's sovereignty (Ecclesiastes 5:7).
Illustration hooks
- A parent agonizing over which school to choose for a child, knowing that the full outcome will only be known years later, if ever.
- A person in midlife who feels time speeding up, realising how many days are already behind them, and wondering if they used them well.
- Someone who worked hard to build a business or ministry, only to see it taken in a different direction after they step away.
Questions your congregation is asking
- How can I make wise decisions if I can't know what is truly good for me?
- Does this verse mean we should stop planning or striving?
- How do I live with uncertainty and fear of the future without becoming paralyzed?
Leading a Discussion
This verse confronts us with our limited perspective. Qoheleth uses two rhetorical questions to show what we cannot know: the nature of the good and the course of the future. Let the discussion move from observing this reality to trusting the God who holds both.
Discussion questions
- What does the verse say about human ability to know what is good? Write down the two questions in your own words.
- Why does the Preacher repeat 'who knows?' and 'who can tell?' What effect does this repetition have on the reader?
- How does the image of a shadow shape your understanding of life? What other Scripture passages use this image (e.g., Job 8:9, Psalm 39:5)?
- What does the phrase 'under the sun' suggest about the perspective from which Qoheleth is speaking? How does that perspective influence his conclusions here?
- In what specific areas of your life do you most feel the pressure to know what is 'good'? How does this verse challenge that pressure?
- How can Christians respond to this honest assessment of ignorance without falling into despair or apathy? What resources does the Bible give for living with uncertainty?
- If you had to state the practical takeaway of Ecclesiastes 6:12 in one sentence for someone who has never read this book, what would you say?

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes that Christians who hold the view that God reveals future events point to this verse, while others understand it as showing that only God knows what comes next. Both seek to be faithful to Scripture.
Barnes' Notes on the Bible Protestant 1832
Barnes clarifies that the phrase “after him” refers to what a person accomplishes on earth in their own sphere of action after someone else has departed this life. He sees it as pointing to the successor’s activities and decisions now, not to an afterlife or spiritual continuation.
Cambridge Bible for Schools and Colleges Anglican 1880
Christians who hold Pyrrhonism say no one can know what is truly good for a person. They view life as a shadow without real substance.
Gill's Exposition of the Bible Baptist 1748
Gill notes that human life is short (like a shadow or a bird flying away) and full of uncertainty. He says because people do not know what will happen after death it is best to be content with what they have.
Jamieson-Fausset-Brown Commentary Protestant 1871
Some read this as meaning that what seems bad now turns out to be good later. Others understand it as pointing to deeper spiritual truths. Both seek to be faithful to Scripture.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch points out that no one can know what is truly good for a person in life because humans are confined to the present and cannot see the future. Our lives are brief and shadow-like, making us like simple drops in history's stream, unable to look beyond our own limited existence.
Lange's Commentary Reformed 1857
Lange argues that the passage condemns not merely greed but the whole struggle for earthly happiness—wealth, honor, long life, many children. True wisdom lies not in restless striving but in contented, grateful enjoyment of what is present, however humble. The wise man's modest walk is better than the fool's insatiable wandering.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry notes that what people most desire often turns out to be harmful rather than helpful. He says this shows how foolish it is to trust human plans and possessions.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley argues that no one can know whether wealth or poverty is truly better, because life itself is fleeting and hollow. Even the things we accumulate have no lasting substance, and we cannot take comfort in leaving them to others, since we have no idea who will inherit them or how they will be used.
