Isaiah 48:4 · KJV


Context

2

For they call themselves of the holy city, and stay themselves upon the God of Israel; The LORD of hosts is his name.

3

I have declared the former things from the beginning; and they went forth out of my mouth, and I shewed them; I did them suddenly, and they came to pass.

4

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

5

I have even from the beginning declared it to thee; before it came to pass I shewed it thee: lest thou shouldest say, Mine idol hath done them, and my graven image, and my molten image, hath commanded them.

6

Thou hast heard, see all this; and will not ye declare it? I have shewed thee new things from this time, even hidden things, and thou didst not know them.


Commentary

KJV Study Commentary
The description 'thy neck is an iron sinew, and thy brow brass' depicts stubborn, unyielding resistance to God - a stiff neck that won't bow and a hardened forehead that won't shame. This echoes Exodus 32:9's 'stiffnecked people' and anticipates Romans 2:5's 'hardness and impenitent heart.' The metaphor shows that sin is fundamentally volitional stubbornness requiring supernatural grace to break.

Historical & Cultural Context

Israel's persistent idolatry despite repeated judgments demonstrated this stubborn resistance. The same stubbornness that refused prophets would later crucify Christ, showing that unregenerate human nature remains unchanged across generations.

Reflection Questions

  1. In what areas of life is your 'neck' stiff - resistant to God's clear direction?
  2. How does recognizing your natural stubbornness increase appreciation for God's grace in converting you?
