King James wording
King James Version
For who knoweth what is good for man in this life, all the days of his vain life which he spendeth as a shadow? for who can tell a man what shall be after him under the sun?THE KEY
Life’s shadow is the limit inside which no one can give a final account of what is good or what comes next.
THE MEANING
You live inside days that pass like a shadow, and the verse leaves open what is truly good for you across them. The future after you remains beyond what anyone can tell; human knowing meets a real edge here.
WHAT THIS UNDOES
It undoes the belief that wisdom can guarantee a final answer about which life is good or what lies ahead.
THE ROOT
צֵל
tsel
GROWS FROM
צלל
tsll
To grow dark or be shaded.
“like a shadow” in this verse is tsel. The root links the shade cast with the darkening that makes things less visible. Here, life is not simply short; it passes as something already slipping from sight, while the future remains beyond view.
ALSO GROWS
tsel: Shadow, shade.
צֵל
This is the word Ecclesiastes uses: the days of life pass like something that cannot be held in view.
tsalal: To grow dark or become shaded.
צָלַל
This verbal branch makes the image active: life passes through a darkening, not merely a count of brief days.
יוֹדֵעַ
yodea
GROWS FROM
ידע
yada
To know, recognize, or perceive; knowing by encounter, not information alone.
“knoweth” in this verse is yodea. The question is not only whether you possess facts about a good life; yada speaks of knowing and perceiving. The verse leaves the good within the limits of human perception across days that are already passing.
ALSO GROWS
da'at: Knowledge, understanding.
דַּעַת
This noun from the same root shows knowledge as something perceived, while the verse asks whether anyone can perceive what is truly good across a whole life.
madda: Knowledge, understanding.
מַדָּע
The same seed again names what can be known; Ecclesiastes places a boundary around that knowing when it turns toward the future.
יַגִּיד
yaggid
GROWS FROM
נגד
nagad
To be in front; in this verb form, to declare or make known.
“tell” in this verse is yaggid. The verse asks who can make the future explicit to another person. The root’s sense of what stands in front sharpens the question: no one can get ahead of what is coming and announce it with certainty.
ALSO GROWS
maggid: One who declares or tells.
מַגִּיד
This branch names the person who makes something known, precisely the role the verse asks whether anyone can fulfill about the future.
nagid: Leader, ruler; one who stands in front.
נָגִיד
The same consonants connect declaration with standing ahead, making the verse’s question about who can speak for what lies ahead more pointed.
THE PATTERN
Human life is brief, and its future exceeds what human knowledge can disclose.
Since his days are cut, and the number of his months is with you, you set his carved limits that he cannot pass over.Humankind is like vapor; his days are as a shadow that passes over.You do not know what tomorrow holds. For what is your life? You are a mist, showing itself for a little while, and then made unseen.THE THREAD
For he does not know what will be, and as it will be, who will declare it to him?This verse repeats both movements: ידע (yada), “know or perceive,” and נגד (nagad), “declare or make known.” The question shifts from what is good in a brief life to when the future arrives, showing the same edge around knowing and announcing what comes next.
