Isaiah 48

KJV · Chapter 48/66

1Hear ye this, O house of Jacob, which are called by the name of Israel, and are come forth out of the waters of Judah, which swear by the name of the Lord, and make mention of the God of Israel, but not in truth, nor in righteousness.

2For they call themselves of the holy city, and stay themselves upon the God of Israel; The Lord of hosts is his name.

3I 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.

4Because I knew that thou art obstinate, and thy neck is an iron sinew, and thy brow brass;

5I 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.

6Thou 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.

7They are created now, and not from the beginning; even before the day when thou heardest them not; lest thou shouldest say, Behold, I knew them.

8Yea, thou heardest not; yea, thou knewest not; yea, from that time that thine ear was not opened: for I knew that thou wouldest deal very treacherously, and wast called a transgressor from the womb.

9For my name’s sake will I defer mine anger, and for my praise will I refrain for thee, that I cut thee not off.

10Behold, I have refined thee, but not with silver; I have chosen thee in the furnace of affliction.

11For mine own sake, even for mine own sake, will I do it: for how should my name be polluted? and I will not give my glory unto another.

12Hearken unto me, O Jacob and Israel, my called; I am he; I am the first, I also am the last.

13Mine hand also hath laid the foundation of the earth, and my right hand hath spanned the heavens: when I call unto them, they stand up together.

14All ye, assemble yourselves, and hear; which among them hath declared these things? The Lord hath loved him: he will do his pleasure on Babylon, and his arm shall be on the Chaldeans.

15I, even I, have spoken; yea, I have called him: I have brought him, and he shall make his way prosperous.

16Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now the Lord God, and his Spirit, hath sent me.

17Thus saith the Lord, thy Redeemer, the Holy One of Israel; I am the Lord thy God which teacheth thee to profit, which leadeth thee by the way that thou shouldest go.

18O that thou hadst hearkened to my commandments! then had thy peace been as a river, and thy righteousness as the waves of the sea:

19Thy seed also had been as the sand, and the offspring of thy bowels like the gravel thereof; his name should not have been cut off nor destroyed from before me.

20Go ye forth of Babylon, flee ye from the Chaldeans, with a voice of singing declare ye, tell this, utter it even to the end of the earth; say ye, The Lord hath redeemed his servant Jacob.

21And they thirsted not when he led them through the deserts: he caused the waters to flow out of the rock for them: he clave the rock also, and the waters gushed out.

22There is no peace, saith the Lord, unto the wicked.

Summary

God rebukes Israel for swearing by his name without sincerity, and explains that he announced the future in advance precisely so that no one could credit the events to idols. He calls the people to leave Babylon with joy, for they have been redeemed.

Explanation

God explains his prophetic strategy: announcing events before they happen, specifically so that when the people saw the fulfillment, they could not say, 'my idol did this.' The metaphor of Israel being refined 'in the furnace of affliction' (not like pure silver, but imperfectly) honestly acknowledges that the people's process of discipline was neither easy nor did it produce total perfection. The final command, 'go out from Babylon, flee from the Chaldeans... declare this with a shout of joy,' anticipates the physical return of the exiles decades later, met with festive joy rather than fear. The practical application today is that God sometimes reveals his plans in advance precisely to strengthen our faith when events come to pass, so that we do not attribute to luck or coincidence what is in fact his work.

Fun facts

  • The expression 'your forehead is bronze' (v. 4) was an ancient way of describing extreme stubbornness, comparing a stubborn person's head to the hardness of metal — the same image survives today in expressions like the English 'hardheaded' or the Portuguese 'cabeça dura' ("hard head").
  • The final verse, 'there is no peace, says the Lord, for the wicked,' is repeated almost word for word at the end of chapter 57, functioning as a refrain that divides major sections of the book of Isaiah.

Verse-by-verse explanation

  1. Isaiah 48:1Calling the people by the name of Israel, but saying they swear “not in truth, nor in righteousness,” is the same criticism other prophets make of surface-level religion: using the right name without living up to it.
  2. Isaiah 48:2Leaning “upon the God of Israel” from the holy city reinforces that the problem isn’t a lack of religious identity, but the gap between religious talk and the people’s actual practice.
  3. Isaiah 48:3“I did them suddenly, and they came to pass” describes the quick fulfillment of old prophecies, an argument repeated in the book to prove the reliability of everything still to come.
  4. Isaiah 48:4A neck as hard as iron and a brow of brass are images of extreme stubbornness. It’s an ancient way of describing someone completely resistant to changing their mind, even after seeing everything God already announced come true.
  5. Isaiah 48:5Announcing things before they happen is presented as a deliberate safeguard against one specific temptation: that the people would credit some idol instead of recognizing the real source of the fulfilled prophecy.
  6. Isaiah 48:6“New things... even hidden things” contrasts with what was already announced before: now the text promises to reveal something unprecedented, something not even the most attentive of the people would have already heard.
  7. Isaiah 48:7Insisting that these things were “created now, and not from the beginning” closes off any chance for the people to claim they already knew in advance, reinforcing that the revelation is genuinely new.
  8. Isaiah 48:8“A transgressor from the womb” is a harsh accusation: the people’s tendency toward unfaithfulness is described as something rooted from the very start, not a recent or isolated lapse.
  9. Isaiah 48:9“For my name’s sake” explains why the punishment isn’t even greater: God’s patience is presented as care for His own reputation, not approval of the people’s behavior.
  10. Isaiah 48:10Saying that the people were refined, but not as silver, is a verse debated among scholars: it may mean that the suffering of exile was not as thorough a refining as silver’s, or that it was different from it. Either way, the affliction is described as the process that tested the people.
  11. Isaiah 48:11Repeating “for mine own sake” reinforces the reason given in the previous verse: the honor of God’s own name is what prevents the people’s total destruction, an argument that returns in similar form in chapter 43.
  12. Isaiah 48:12“I am the first, I also am the last” repeats almost word for word the titles used in chapters 41 and 44, a fixed formula in the book affirming God’s uniqueness and eternity.
  13. Isaiah 48:13Measuring out the heavens “spanned” with His own hand picks up the same image of creation on an impossible scale already used in chapter 40, an argument repeated to justify the authority of the one speaking.
  14. Isaiah 48:14The question about who else announced these things prepares the mention that God’s will against Babylon and the Chaldeans will be carried out, tying this chapter again to the theme of Babylon’s fall.
  15. Isaiah 48:15“He shall make his way prosperous” probably refers to Cyrus, whose military success against Babylon is credited here to God’s direct action, not to the king’s own luck or personal skill.
  16. Isaiah 48:16“There am I” reinforces that God is not an explanation invented after the fact: He affirms having been present from the very beginning of everything that has already happened, including events still to come.
  17. Isaiah 48:17“Which teacheth thee to profit” describes God as a kind of practical guide, not only as a source of punishment, contrasting with the harsher tone at the start of the chapter.
  18. Isaiah 48:18The lament “O that thou hadst hearkened” imagines an alternate past: had the people obeyed, peace would have been as constant as a river and righteousness as vast as the sea, but the reality they lived was quite different.
  19. Isaiah 48:19Comparing the people’s descendants to sand repeats the ancient promise made to Abraham in Genesis, recalling that the promised multiplication would still have been possible had obedience accompanied faith.
  20. Isaiah 48:20The order to go forth from Babylon and flee the Chaldeans is the concrete command to leave exile and return home. It echoes the departure from Egypt centuries before, as though this return were a new exodus.
  21. Isaiah 48:21Recalling the water that came out of the rock in the wilderness points back to the book of Exodus, when Moses strikes the rock and water gushes out. It’s another example of the book’s pattern of using the Exodus past as a model for the new deliverance expected.
  22. Isaiah 48:22This line, which also closes chapter 57, works almost like a refrain: however many promises of peace there are for the obedient, the text makes clear it doesn’t automatically extend to those who insist on evil.
