This verse in the King James

King James wording

King James Version

I, even I, have spoken; yea, I have called him: I have brought him, and he shall make his way prosperous.

THE KEY

The way begins to advance after the voice has already spoken, called, and brought the traveler forward.

THE MEANING

The verse holds a sequence: the voice speaks, calls, and brings; then the called one’s way advances. Your path does not begin from nowhere; movement is already preceded by a summons and a bringing forward. Here, prosperity is a way making headway, not merely having more.

WHAT THIS UNDOES

The lie that every forward step must originate in your own effort.

THE ROOT

יַצְלִיחַ

yatsliach

GROWS FROM

צלח

ts-l-ḥ

to advance, succeed, or make headway

“push his way through” in this verse is yatsliach. English “prosperous” can sound like wealth, but this root carries the motion of a course advancing. Another form describes something surging upon a person; here, that forward movement follows the call and bringing.

ALSO GROWS

tsalach: advance, succeed, prosper

צָלַח

This is the root’s basic movement of getting forward, which gives “make his way prosperous” the sense of a way making headway.

vattitslach: rush, come strongly upon

וַתִּצְלַח

The same root describes the LORD’s breath rushing upon Saul in 1 Samuel 10:10, revealing the force of movement carried by this word.

קְרָאתִיו

qerativ

GROWS FROM

קרא

q-r-ʾ

to call out, summon, or proclaim

This is more than identifying someone by name: the root carries the act of summoning with a voice. The path’s advance follows a person who has already been addressed and called into movement.

ALSO GROWS

qara: call out, summon, proclaim, or read aloud

קָרָא

The verse’s “called” belongs to a root in which a voice reaches outward and summons someone.

miqra: convocation, proclamation, or public reading

מִקְרָא

This branch can name a gathered assembly or a proclaimed reading, showing how a call can bring people into presence together.

הֲבִיאֹתִיו

hevi'otiv

GROWS FROM

בוא

b-w-ʾ

to come or enter; in this form, to cause someone to come

The Hebrew verb for “brought” is a causative form of “come.” The speaker does not only name a direction; the verse presents the called one as being brought into motion before his way advances.

ALSO GROWS

bo': come, enter, arrive

בּוֹא

This is the underlying movement that the verse’s causative form sets in motion for the called person.

mavo: entrance, approach, or coming in

מָבוֹא

This branch makes the root’s movement concrete as arrival at an entrance or approach, echoing the verse’s progression from call to bringing forward.

THE PATTERN

Fruitful progress begins in a source that is already present and sustaining, then appears in the path’s own movement.

And his master saw that the LORD was with him, and that the LORD made all that he did break through in his hand.

Genesis 39:3 · SDVJoseph’s work prospers alongside the LORD’s presence with him, so the outcome follows a sustaining source.

And he becomes like a tree planted by the channels of the waters, that gives its fruit in its season; its leaf does not wither; whatever he does, he breaks through.

Psalm 1:3 · SDVThe planted tree bears fruit and endures, showing progress as the growth of something rooted and nourished.

I am the vine, and you are the branches. The one who remains in me, and I in him, this one bears much fruit, for apart from me you can do nothing.

John 15:5 · SDVFruitfulness follows abiding in its source; the visible work grows from a connection already sustaining it.

THE THREAD

And he said to me, The LORD, before whom I walk, will send his messenger with you, and make your road break through; and you shall take a wife for my son from my kindred, and from my father's house.

Genesis 24:40 · SDV

The same verb ⁨צלח⁩ (tsalach, advance or make prosper) governs “prosper thy way” here and “make his way prosperous” in Isaiah. In both verses, the way’s advancement follows a sending already set in motion, so “prosper” carries the image of a path moving forward under guidance.
