This verse in the King James

King James wording
Strengthen ye the weak hands, and confirm the feeble knees.

The “weak” hands are literally hands gone slack, so the verse calls strength to the exact point where the grip has let go.

The verse speaks into the moment when your capacity falters: hands hang, and knees begin to buckle. It names that weakness directly, then calls those same places toward steadiness. The point where support gives way is also the point the verse addresses with strength.

WHAT THIS UNDOES

When my strength gives way, there is nothing left to steady me.

רָפוֹת

raphot

GROWS FROM

רפה

r-p-h

To slacken, droop, or let fall; to become weak.

“hands that have let go” in this verse is raphot. English “weak” can sound like a fixed lack of strength; ⁨רָפוֹת⁩ carries the image of hands slackening or falling. The verse calls strength into that loosened place, restoring firmness where the grip has given way.

ALSO GROWS

raphah: To slacken, let drop, or release.

רָפָה

This verb carries the motion pictured by the slack hands: the grip loosens and the hands droop.

harpu: Let go; release your grip.

הַרְפּוּ

The same root connects physical slackness with letting go, revealing that the weakness named here includes a loosening of hold.

כֹּשְׁלוֹת

kosh'lot

GROWS FROM

כשל

k-sh-l

To stumble, totter, or fail; to lose footing.

“knees that buckle” in this verse is kosh'lot. The knees are described through the language of stumbling, not merely a lack of muscle. Their support is failing in motion, which makes the call to steady them precise.

ALSO GROWS

kashal: To stumble, totter, or fail.

כָּשַׁל

This verb makes visible how the knees in the verse are losing their footing.

mikshol: A stumbling block or obstacle.

מִכְשׁוֹל

The same root names what causes a stumble, linking failing knees with the loss of secure footing.

אַמֵּצוּ

ammetsu

GROWS FROM

אמץ

ʾ-m-ts

To be strong or make firm; to strengthen and encourage.

“steady” in this verse is ammetsu. “Confirm” here carries the sense of making firm or strong. Set beside slack hands and stumbling knees, the word names a return to steadiness at the body’s points of failure.

ALSO GROWS

omets: Strength or courage.

אֹמֶץ

The related noun names the strength or courage being restored to the failing knees.

me'ammets: Strengthening; making strong.

מְאַמֵּץ

This form makes the action explicit: what has begun to fail is made firm.

Faltering strength is met by strengthening the exact places where support gives way.

But Moses' hands were heavy. And they took a stone and set it under him, and he sat upon it. And Aaron and Hur held up his hands, one on this side and the other on that side, and his hands were steady until the sun went down.
Exodus 17:12 · SDVWhen Moses’s hands grow heavy, others hold them up until they are steady, making faltering strength a point of shared support.
He gives power to the faint, and to those without might he multiplies strength.
Isaiah 40:29 · SDVThe faint and powerless receive increased strength, moving from depleted capacity toward renewed firmness.
Therefore straighten the hands that hang down and the knees that have been loosened.
Hebrews 12:12 · SDVThe hanging hands and feeble knees echo Isaiah’s image, naming the very places where strength and steadiness are needed.
Do not fear, for I am with you. Do not look about in dismay, for I am your God. I will grip you, and I will help you, and I will hold you up with the right hand of my alignment.
Isaiah 41:10 · SDV

The word translated “confirm” here and “strengthen” there comes from the same root, ⁨אמץ⁩ (ʾ-m-ts), meaning to make firm or strong. Isaiah 41:10 gives the same strengthening as a direct promise: the failing places are met with help and upheld.
