This verse in the King James

King James wording
Hast thou not known? hast thou not heard, that the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.

Earth has edges, but the understanding of its Creator has no edge your searching can reach.

The God of the ages, maker of earth’s farthest edges, does not tire; his understanding has no boundary a human search can reach. Your exhaustion and partial sight are real, but they do not mark the limit of the One who made and understands the whole.

WHAT THIS UNDOES

The limit of what you can understand is not the limit of what God understands; your exhaustion is not proof that the power sustaining you has run out.

קְצוֹת

qetsot

GROWS FROM

קצה

qatsah

edge, extremity, or boundary

The earth’s farthest edges are named as real limits, then set beside an understanding no search can reach. The verse lets creation have an edge without giving its Creator one.

ALSO GROWS

qatseh: edge, end, or extremity

קָצֶה

It makes the earth’s boundary concrete: a place where something reaches its limit.

miq-tseh: from the edge or extremity

מִקְצֵה

This form carries the same root sense of a boundary or farthest point.

תְּבוּנָתוֹ

tevunato

GROWS FROM

בין

bin

to discern or understand by distinguishing

This word belongs to a family that includes ⁨בֵּין⁩ (bein), “between.” The verse speaks of discernment that sees distinctions, yet no search can exhaust its reach.

ALSO GROWS

binah: understanding or discernment

בִּינָה

It names the discerning capacity that the verse says cannot be searched out.

bein: between

בֵּין

It shares the root’s language of distinguishing one thing from another.

יִיגָע

yiga

GROWS FROM

יגע

yaga

to toil or grow weary

“nor tire” in this verse is yiga. The verse denies God the depletion named by this root. In verse 31, the same root appears in the promise that those who wait upon the LORD “shall ... not be weary,” carrying divine inexhaustibility into human renewal.

ALSO GROWS

yaga: to toil or grow weary

יָגַע

It is the verb family behind the weariness the verse says does not overtake God.

yegi’ah: labor or toil

יְגִיעָה

It shows the same root describing the effort that can exhaust a person.

The limits of creaturely strength and understanding do not limit God’s sustaining power or wisdom.

Look, the watcher of Israel neither nods nor sleeps.
Psalm 121:4 · SDVIsrael’s keeper does not need sleep or recovery before he can keep watch.
Great is our Lord, and great in power; his discernment is without number.
Psalm 147:5 · SDVThe Lord’s understanding cannot be measured as a finite quantity.
O the depth of the riches of both wisdom and knowledge of God! How beyond searching out are his judgments, and how beyond tracking are his ways!
Romans 11:33 · SDVGod’s wisdom and ways remain beyond the search that would contain them.
But those who wait upon the LORD exchange their strength; they rise on wings like eagles; they run and do not tire; they walk and do not faint.
Isaiah 40:31 · SDV

In both verses, “weary” comes from ⁨יגע⁩ (yaga), “to toil or grow weary.” Verse 28 names the exhaustion God does not enter; verse 31 uses that same root for the exhaustion that no longer defines those whose strength is renewed in the LORD.
