Because I knew that thou art obstinate, and thy neck is an iron sinew, and thy brow brass;

Isaiah 48:4 · KJV

The analysis reads the King James wording.

King James Version The King James Version, first published in 1611. Selah Verse shows the standard text.

THE KEY

The verse gives obstinacy a body: hardness fixes the neck and covers the brow.

THE MEANING

Resistance here is more than a passing refusal; it has become a posture that will not turn. The speaker knows this hardness, and the iron sinew and brass brow make it visible from neck to face. The image leaves no softness in the whole stance.

WHAT THIS UNDOES

It undoes the belief that obstinacy is only a private opinion: here it shapes the whole posture, fixing the neck against a turn.

THE ROOT

קָשֶׁה

qasheh

GROWS FROM

קשה

q-sh-h

To be hard, severe, or difficult.

The Hebrew word rendered “obstinate” is itself a word for hardness, and the image immediately carries that same quality into the iron neck and brass brow. What English presents as a character trait is also a texture: resistance has become hard to bend.

ALSO GROWS

qashah: To be hard, harsh, or difficult; to harden.

קָשָׁה

This verbal branch makes the verse’s obstinacy an active hardening, not just a label for someone’s temperament.

qeshi: Hardness or stubbornness.

קְשִׁי

This noun names the fixed quality that the iron sinew and brass brow embody.

THE PATTERN

Resistance becomes visible as a neck that will not turn.

And the LORD said unto Moses, I have seen this people, and, behold, it is a stiffnecked people:

Exodus 32:9 · KJVThe same hard-necked image names a people whose resistance has become a settled posture.

He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.

Proverbs 29:1 · KJVHere the neck hardens through repeated refusal, making the same inner resistance bodily visible.

Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye.

Acts 7:51 · KJVThe fixed neck appears alongside resistance in heart and ears, extending the image from posture to perception.

THE THREAD

And the LORD said unto Moses, I have seen this people, and, behold, it is a stiffnecked people:

Exodus 32:9 · KJV

“Stiffnecked” carries the same Hebrew hardness-and-neck image as Isaiah’s obstinate neck. The shared phrase shows that the iron sinew is more than an added comparison: it makes the stubborn posture visible.
