This verse in the King James

King James wording
And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.

The LORD makes Pharaoh’s heart strong in refusal, so even wonders confront a grip that will not release.

The verse holds a stark tension: the LORD strengthens Pharaoh’s heart, and Pharaoh does not release the people. Wonders are in Moses’ hand, yet their presence does not end the captivity. Divine agency and withheld release occupy the same sentence.

WHAT THIS UNDOES

The belief that wonders automatically make a ruler relent and end captivity is undone here: signs and continuing refusal coexist.

אֲחַזֵּק

achazzeq

GROWS FROM

חזק

chazaq

Be strong, prevail; in this form, strengthen or make firm.

“grip” in this verse is achazzeq. The root carries firmness and strength beneath the English word harden. Here that strengthening becomes firmness in refusal, leaving the LORD’s stated action and Pharaoh’s withholding bound together.

ALSO GROWS

chazaq: Be strong, grow strong.

חָזַק

This basic form makes the strength within the verse’s hardening language visible.

chizzeq: Strengthen, make firm.

חִזֵּק

This intensive form expresses the force of the LORD’s action toward Pharaoh’s heart.

יְשַׁלַּח

yeshallach

GROWS FROM

שלח

shalach

Send forth, send away, release.

The verb beneath “let the people go” is ⁨יְשַׁלַּח⁩ (yeshallach, “send or release”): Pharaoh refuses to send the people away. The verse makes the captivity concrete as release withheld.

ALSO GROWS

shalach: Send, send away, release.

שָׁלַח

This basic verb names the release Pharaoh refuses.

shilleach: Send away, dismiss.

שִׁלֵּחַ

This related form carries the same movement outward that the people are denied.

מֹשֶׁה

Moshe

GROWS FROM

משה

mashah

Draw out, especially draw out of water in the narrative naming.

“Moses” in this verse is Moshe. Moshe (⁨מֹשֶׁה⁩, Moshe, “the one drawn out”) echoes ⁨מָשָׁה⁩ (mashah, “draw out”); Exodus 2:10 makes that connection in the naming. His name stands beside ⁨מִצְרַיִם⁩ (Mitzrayim, “the two narrows”): the one drawn out is now sent into constriction where release is denied.

ALSO GROWS

mashah: Draw out, especially from water.

מָשָׁה

This verb carries the action echoed in Moses’ name.

Moshe: Moses; the one drawn out through the name’s wordplay.

מֹשֶׁה

His name holds the image of being drawn out as he is sent toward a people awaiting release.

A heart made firm can sustain withheld release even as signs and divine action confront it.

And I will stiffen Pharaoh's heart and multiply my signs and my wonders in the land of Egypt.
Exodus 7:3 · SDVSigns and wonders multiply while the LORD names Pharaoh’s hardened heart as part of the same confrontation.
But Sihon, king of Heshbon, would not let us cross through him, for the LORD your God made stiff his breath, and made his heart firm, so that he might give him into your hand, as on this day.
Deuteronomy 2:30 · SDVThe LORD hardens Sihon’s spirit as Sihon refuses passage, joining divine action with withheld release.
So then he shows faithful love to whom he wills, and whom he wills, he hardens.
Romans 9:18 · SDVThe verse holds hardening alongside mercy, keeping divine agency visible where human responses remain closed.
But the LORD gripped Pharaoh's heart, and he did not let the children of Israel go.
Exodus 10:20 · SDV

Exodus 4:21 uses ⁨חזק⁩ (chazaq, “be strong, strengthen”) in the LORD’s declaration that he will strengthen Pharaoh’s heart. Exodus 10:20 repeats the same root in the report of Pharaoh’s hardened heart, again joined to his refusal to release the people.
