This verse in the Selah Decoded Version

The verse exposes age as a false witness: your many days cannot testify to what came before your first day.

You enter a world already underway, so the length of your life cannot make you an eyewitness to what came before it. Time may deepen what you perceive, but it does not erase the boundary of your beginning.

WHAT THIS UNDOES

It undoes the belief that living long enough means you were present for, or can fully know, everything that came before you.

יָדַעְתָּ

yadaʿta

GROWS FROM

י־ד־ע

To know, perceive, or recognize.

“Knowest” in this verse is yadaʿta. The question uses yadaʿ, “know” or “perceive”: it asks whether you can truly know this because you were already there. The root makes the issue one of perception and knowing, while the verse points to the limit that no number of days crosses.

ALSO GROWS

daʿat: knowledge

דַּעַת

This noun shares the root and shows that “knowing” belongs to the same word family as the verse’s question about what you can perceive.

hodiʿa: made known, informed

הוֹדִיעַ

This causative form of the root means to make something known; it highlights the difference between receiving knowledge and having lived through what came before your birth.

תִּוָּלֵד

tivvaled

GROWS FROM

י־ל־ד

To give birth or bring forth.

The verse ties the claim to know to being born “then”: your own beginning is the measure of what you could have witnessed. The root also gives Hebrew words for a child and for generations, keeping birth connected to the unfolding of life across time.

ALSO GROWS

yeled: child

יֶלֶד

A child is one who has been brought forth; this branch makes the personal starting point in “because thou wast then born” concrete.

toledot: generations, offspring

תּוֹלְדוֹת

Generations are what is brought forth over time, echoing the verse’s contrast between a beginning and the events that precede it.

מִסְפַּר

mispar

GROWS FROM

ס־פ־ר

To count or recount.

The “number” of your days comes from a root associated with counting and recounting. The verse tests whether a life tallied as long can serve as testimony to events from before that life began; the count itself cannot supply that witness.

ALSO GROWS

safar: count, recount

סָפַר

This verb shares the root and makes the verse’s “number of thy days” a count of lived time.

sefer: book, written record

סֵפֶר

This related word evokes a record: a long count of days is still not a record of what you could not witness.

A human lifespan cannot supply eyewitness knowledge of what preceded human life.

Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
Job 38:4 · KJVThe question places human understanding beside a beginning that came before the reader’s lifetime.
Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.
Psalm 90:2 · KJVThe psalm sets the world’s beginning beyond the span of any human life.
For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
1 Corinthians 13:12 · KJVThe verse names the present limit of human knowing, even within a life that sees and learns.
Hast thou perceived the breadth of the earth? declare if thou knowest it all.
Job 38:18 · KJV

“Knowest” here is the same Hebrew root, ⁨י־ד־ע⁩ (y-d-ʿ; yadaʿ), as “Knowest thou it” in verse 21. Verse 18 questions whether you perceive the earth in its full breadth; verse 21 asks whether your days make you a witness to what preceded your birth.
