King James wording
King James Version
For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.THE KEY
Knowing more can hurt because knowledge makes reality harder to keep at a distance.
THE MEANING
As your wisdom expands, you notice more of what is painful, and deeper knowledge can make that pain more vivid. This verse names the ache of seeing clearly without calling insight useless.
WHAT THIS UNDOES
It undoes the belief that greater understanding automatically brings comfort: clearer sight can expose pain.
THE ROOT
דַּעַת
daʿat
GROWS FROM
י־ד־ע
y-d-ʿ
To know, recognize, or perceive through encounter.
The word for knowledge grows from a root meaning to know or perceive. The verse links that deeper contact with reality to increased pain: what is more clearly seen can also be more deeply felt.
ALSO GROWS
yādaʿ: To know, recognize, or perceive.
יָדַע
The verb behind knowledge frames its increase as deeper contact with what is seen.
dēʿāh: Knowledge or understanding.
דֵּעָה
This related noun shows the root can name both the act of knowing and the understanding that grows from it.
כָּעַס
kaʿas
GROWS FROM
כ־ע־ס
k-ʿ-s
To be provoked or vexed; anger, vexation, or grief.
The word rendered grief can also carry anger and vexation, the sting of being provoked. Wisdom’s cost here is abrasive: clearer sight can unsettle and agitate, not only sadden.
ALSO GROWS
kaʿas: To feel vexation or anger.
כָּעַס
The verb makes the grief active and stirred, rather than a distant, abstract sadness.
hikʿis: To provoke someone or make them angry.
הִכְעִיס
This related form shows how the same root can describe the force that produces vexation.
מַכְאוֹב
makʾov
GROWS FROM
כ־א־ב
k-ʾ-b
To hurt, ache, or suffer pain.
“adds pain” in this verse is makʾov. The final word is rooted in hurting and aching, giving sorrow the force of felt pain. Knowledge increases not just a passing mood but an ache that is lived.
ALSO GROWS
kāʾav: To feel pain or ache.
כָּאַב
The verb makes clear that sorrow here belongs to the language of hurting.
yikʾav: He will ache or feel pain.
יִכְאַב
This verbal form shows the root naming pain as something experienced, not merely contemplated.
THE PATTERN
Clearer awareness can expose pain, because seeing what is true does not automatically make it easier to bear.
And the eyes of them both were opened, and they perceived that they were bare, and they sewed fig leaves together, and made for themselves waistcloths.Channels of waters run down from my eyes, because they do not guard your instruction.O worn-down man that I am! Who will bring me out of the body of this death?THE THREAD
And the eyes of them both were opened, and they perceived that they were bare, and they sewed fig leaves together, and made for themselves waistcloths.Genesis uses the same root as Ecclesiastes’ word for knowledge: יָדַע (yādaʿ, to know or perceive). In both verses, knowing is an encounter that brings something painful into view.
