The big picture
Isaiah 48 closes this movement of the book by confronting the uncomfortable distance between Israel's religious vocabulary and Israel's actual hearing. The people carry the names Jacob, Israel, Judah, the holy city, and the God of Israel, yet they invoke those names "not in truth, nor in righteousness." Their resistance is described as an iron neck and a brass forehead. Earlier predictions and newly announced acts are explained as deliberate answers to that stubbornness, blocking Israel from crediting idols or claiming it knew everything already. Still, judgment has not ended in extinction. The LORD restrains anger for his own name and glory, refining a people he continues to claim. The Book of Isaiah returns to creation, Cyrus's commissioned work against Babylon, and the persistent command to hear. It ends with a call to leave Babylon singing of redemption, but adds one last hard sentence: geographic release is not identical with peace. Wickedness can cross the border too.

Scripture beside the summary
Isaiah · King James Version · 22Isaiah 48:1-5
The Right Religious Names and an Iron Neck
The opening piles up honored identities: house of Jacob, name of Israel, waters of Judah, name of the LORD, God of Israel, holy city. None is dismissed as meaningless, yet all are placed beside the charge "not in truth, nor in righteousness." The problem is not lack of religious vocabulary. It is the gap between naming the right God and responding rightly to him. Isaiah makes stubbornness almost metallic, with an iron sinew for a neck and brass for a forehead. The Book of Isaiah then explains why former events were declared in advance. Prediction is not displayed merely as intellectual superiority. It closes off a false explanation before the event occurs. Israel must not be able to point afterward to a graven image and say, "Mine idol hath done them." The prior word becomes evidence designed for a people whose resistance would otherwise redirect credit toward the very objects that cannot act.
Deep dive
The opening gathers the people's recognized identifiers: Jacob, Israel, Judah, the LORD, and the holy city. None of these labels is treated as meaningless, but their use "not in truth, nor in righteousness" exposes the gap between confession and conduct. The people lean on the name of the God of Israel while remaining resistant to his speech. Isaiah makes the problem internal to a privileged identity rather than merely locating it among foreign worshippers.
The iron sinew of the neck and brass forehead describe resistance with materials that will not readily bend. Earlier prediction is then explained as a deliberate answer to this resistance. By announcing events beforehand, the LORD prevents the people from later attributing them to an image. The argument is not simply that God possesses foreknowledge. He has used declared knowledge to close off a particular false explanation. Israel's stubbornness affects how the divine word is presented, because a saving act without prior declaration might otherwise be credited to the very object unable to perform it.
Words to trace: Israel, name, beginning, declared, image, LORD
Verse-by-verse path
- Isaiah 48:1
“Come forth out of the waters of Judah” pictures descent as flowing from a spring; Psalm 68:26 speaks of blessing the Lord “from the fountain of Israel”. Some read the word as “loins”. “Make mention” is hazkir, to invoke in worship, to say the name aloud. Six marks of belonging are listed before the last clause cancels them.
- Isaiah 48:2
“Stay themselves upon” is nismakhu, to lean one’s weight on, from the verb used for pressing the hand on the head of a sacrifice (Leviticus 1:4). “The holy city” is a title Isaiah uses again in 52:1. They claim the address and lean on the name, and the verse lets the title “LORD of hosts” stand as the rebuke.
- Isaiah 48:3
Four verbs mark the pattern: declared, went forth, shewed, did suddenly. The announcement is long and public; the fulfilment arrives without warning. The book’s own record holds an example: Assyria’s fall was foretold in chapter 10 and came overnight in 37:36-37.
- Isaiah 48:4
“Obstinate” is qasheh, hard. An iron sinew in the neck is the stiff neck of Sinai (Exodus 32:9) turned to metal. A brow of brass is a forehead that cannot blush; Jeremiah 3:3 accuses Israel of having “a whore’s forehead” that “refusedst to be ashamed”.
- Isaiah 48:5
Three words for idols are used: otsev, the shaped thing, from a root that also means pain; pesel, carved; and nesekh, poured metal. “Hath commanded them” imagines the idol issuing orders, when the one who commands in these chapters is the LORD, who commanded the host of heaven (45:12).
Isaiah 48:1-5
King James Version1Hear 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.
Isaiah 48:6-11
New Things Leave No Room for Borrowed Credit
New things answer a second evasion. If earlier declarations prevent Israel from crediting idols, fresh announcements prevent the people from saying, "Behold, I knew them." Isaiah exposes both misplaced credit and retrospective self-importance. The closed ear and long record of treachery mean the coming rescue cannot be explained as a reward for attentiveness. Then the reason for restraint appears twice: "for my name's sake" and "for mine own sake." The Book of Isaiah describes affliction with the language of a furnace while refusing to say the people have been cut off. The phrase "not with silver" is difficult, but the surrounding point is clear enough. Judgment, preservation, and continued choosing exist together in the passage. Survival is not proof that wrongdoing was trivial, and affliction is not proof that the covenant name has been abandoned. The one preserving Israel refuses to surrender his glory to another explanation.
Deep dive
Newly disclosed things answer another possible evasion: the claim that Israel knew all along. The sequence contrasts hearing a declaration with actually possessing the understanding it demands. Verse 8 describes treachery and a closed ear from the beginning, making clear that the coming rescue is not a reward for a long record of attentiveness. The LORD names the people's condition without discovering it belatedly.
The repeated reason for restraint is his own name and praise. The furnace of affliction belongs to refinement and continued choosing rather than complete extermination. The phrase "not with silver" is difficult, and the verse does not supply a technical account of the refining comparison. Its place between deferred anger and the refusal to surrender divine glory makes the preserving purpose clear. The people remain accountable, yet they have not been cut off. Isaiah holds that tension instead of making survival evidence that no judgment was warranted or that the process of affliction was trivial.
Words to trace: sake, heardest, knew, time, affliction, anger
Verse-by-verse path
- Isaiah 48:6
“Will not ye declare it?” turns the witnesses of 43:10 back to their duty: you heard it, now testify. “Hidden things” are netsurot, things kept under guard, sealed away until the moment of their release. What is new cannot be something Israel had already worked out.
- Isaiah 48:7
“They are created now” uses bara of events rather than of matter: the new acts of God are a fresh creation. The verse answers verse 3 point by point: those were declared “from the beginning”; these are “not from the beginning”, and so nobody can claim to have known.
- Isaiah 48:8
“A transgressor from the womb” recalls Jacob seizing his brother’s heel before birth (Genesis 25:26), which Hosea 12:3 treats as the first sign of his character. The same book that says the LORD “formed thee from the womb” (44:2) now says Israel rebelled from the womb. Both are true of Jacob.
- Isaiah 48:9
“Defer mine anger” is ha’arikh af, to lengthen the nostrils, the idiom behind “longsuffering” in the self-description of Exodus 34:6. “Refrain” is chatam, a verb found only here, probably to muzzle or hold in. Anger is held back like a breath not let out.
- Isaiah 48:10
The Qumran Isaiah scroll reads “I have tested thee” where the traditional text has “I have chosen thee”, one letter apart in Hebrew. Egypt was called “the iron furnace” (Deuteronomy 4:20; 1 Kings 8:51); exile is a second furnace, a smelting of the people as silver is smelted.
- Isaiah 48:11
The Hebrew says only “for how should it be profaned?”; the King James supplies “my name” from verse 9. Ezekiel builds a whole argument on this point: Israel’s exile made the nations mock the LORD’s name, and so he acts “for mine holy name’s sake” (Ezekiel 36:20-23).
Isaiah 48:6-11
King James Version6Thou 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.
Isaiah 48:12-16
The First and Last Speaks Into a Changing Sequence of Voices
The command "Hearken unto me" returns with the identity of the speaker: first and last, founder of the earth, one whose right hand spans the heavens. Creation stands ready when called, which makes Israel's repeated failure to hear all the sharper. The assembly is then asked which rival announced the coming action against Babylon. The favored agent fits the Cyrus commission already given in chapters 44 and 45, a human instrument called and prospered for a specific purpose. The Book of Isaiah does not turn that favor into an unrestricted evaluation of the ruler. Verse 16 then introduces a genuine shift in voice: "the Lord GOD, and his Spirit, hath sent me." The speaker is not named, and interpretations differ between prophet, servant, and messianic readings. Isaiah gives enough to notice the sending without enough to erase the ambiguity. What remains clear is that the message claims open, commissioned speech rather than secrecy reconstructed after the event.
Deep dive
The LORD again identifies himself as first and last, with earth and heaven responding together when called. Against that obedient creation stands the people repeatedly commanded to hear. The agent who will carry out the LORD's purpose on Babylon fits the Cyrus commission already given in chapters 44–45. The expression of favor toward him concerns that commissioned role in the present argument; the passage does not turn it into an unrestricted evaluation of the man.
Verse 16 ends with a notable first-person statement about being sent by the Lord GOD and his Spirit. The identity of this speaker is disputed. Some readings hear the prophet or a servant figure; Christian readings have also understood a divine messianic speaker within the sequence. The verse does not provide a new personal name, so the change should be noticed rather than silently assigned a certainty it lacks. What is clear is the repeated contrast with secrecy: the message is presented openly and as commissioned speech, not as an oracle whose meaning is invented only after events have occurred.
Words to trace: hand, hear, LORD, assemble, Babylon, beginning
Verse-by-verse path
- Isaiah 48:12
Verse 1 said the people are “called by the name of Israel”, a name they gave themselves. Here the LORD calls them “my called”, meqora’i, the ones he has summoned. The two uses of the same verb frame the difference between claiming a title and being claimed.
- Isaiah 48:13
“Spanned” is tippechah, spread out with the palm, from tefach, a handbreadth, the width of four fingers. The earth has foundations laid by the one hand and the heavens are spread by the other. When called, heaven and earth “stand up together”, as servants rise when their master enters.
- Isaiah 48:14
“The LORD hath loved him” is said of Cyrus, a striking thing to say of a foreign conqueror, and it names the LORD’s choice rather than Cyrus’s character. Whose “arm” falls on the Chaldeans is left open: Cyrus’s, or the LORD’s own arm, which has been at work since 40:10.
- Isaiah 48:15
“Make his way prosperous” is hitsliach, the verb used of Joseph in Potiphar’s house and in prison: “the LORD made it to prosper” (Genesis 39:3, 23). Four first-person verbs precede it: spoken, called, brought, and the success follows as a consequence.
- Isaiah 48:16
The first half repeats 45:19 almost exactly: “I have not spoken in secret.” The grammar of the last clause allows “the Lord GOD hath sent me, and his Spirit” as well as “the Lord GOD and his Spirit”. The nearest parallel in the book is 61:1: “The Spirit of the Lord GOD is upon me.”
Isaiah 48:12-16
King James Version12Hearken 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.
Isaiah 48:17-19
The River of Peace That Might Have Been
The LORD identifies himself as Redeemer, Holy One, teacher, and guide, then says his instruction is "to profit" Israel. That wording matters because stubborn refusal could otherwise be imagined as resistance to arbitrary demands. The teaching is presented as beneficial and the path as one the guide intended to lead them along. Then comes the ache of the counterfactual: "O that thou hadst hearkened." Peace might have flowed like a river, righteousness like the waves of the sea, and offspring continued with the abundance of sand. The Book of Isaiah makes disobedience costly in concrete terms, not merely a violation of procedure. What was missed includes sustained well-being, continuity, and a name not cut off. The passage does not become a formula explaining every person's suffering by a personal offense. Its subject is Israel's response to known instruction. The tragedy is that the teacher describes the road as one meant for their good.
Deep dive
The LORD identifies himself as teacher and guide, specifying that his instruction is for Israel's benefit. That description answers any suggestion that the closed ear protected the people from harmful divine demands. The lament in verse 18 then uses a counterfactual form: listening would have meant peace like a river and righteousness like the sea's waves. These images convey continuity and abundance rather than a brief interval of relief.
The promised offspring like sand recalls the ancestral scale of increase, but here it appears in a statement of what disobedience has cost. The loss concerns both well-being and the endurance of a name before God. Isaiah does not use this passage to explain every instance of human suffering by a particular personal offense. Its subject is the named people's response to the instruction given them. The teacher's beneficial purpose and the missed outcome are set beside each other, giving the refusal to hear a consequence more concrete than the failure to satisfy a formal requirement.
Words to trace: LORD, bowels, commandments, destroyed, gravel, hadst
Verse-by-verse path
- Isaiah 48:17
“To profit” is lehoil, from ya’al, the verb of 44:9-10, where images are “profitable for nothing”. The idols profit nobody; the LORD teaches his people how to profit. Psalm 32:8 has the same promise: “I will instruct thee and teach thee in the way which thou shalt go.”
- Isaiah 48:18
“O that” is lu, the particle of wistful regret. Psalm 81:13-14 laments in almost the same words: “Oh that my people had hearkened unto me.” Peace “as a river” is taken up again at the end of the book, “I will extend peace to her like a river” (66:12), what was missed here offered once more.
- Isaiah 48:19
There is wordplay in the Hebrew: “the offspring of thy bowels”, me’ekha, will be “like the grains thereof”, kim’otav, grains of sand. Abraham was promised seed “as the sand which is upon the sea shore” (Genesis 22:17). A name cut off was the worst fate for a family, the line ended.
Isaiah 48:17-19
King James Version17Thus 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.
Isaiah 48:20-22
Leaving Babylon Is Not the Whole Meaning of Peace
The command to leave Babylon breaks into proclamation. The departing people are to sing, declare, tell, and carry the news to the end of the earth: "The LORD hath redeemed his servant Jacob." The route through the desert is accompanied by exodus-shaped provision, with water flowing from the rock so the journey away from captivity does not become abandonment in another form. The Book of Isaiah could have ended there in uncomplicated celebration, but verse 22 refuses to do so. "There is no peace ... unto the wicked" lands abruptly after the redemption song. That final line protects the meaning of peace from being reduced to geography. Leaving Babylon is real deliverance, but a changed address does not automatically heal the refusal to hear exposed throughout the chapter. Redemption is proclaimed without qualification, and wickedness is denied peace without qualification. Isaiah leaves both sentences standing, forcing freedom and moral reality to occupy the same ending.
Deep dive
The call to leave Babylon becomes a proclamation carried to the earth's end. The message concerns the LORD's redemption of his servant Jacob, and the following water from the rock recalls the provision associated with the exodus. The old deliverance supplies the language for the new departure. The route through the desert is not imagined as a place where the Redeemer's attention ceases once the people have crossed the city's boundary.
The closing denial of peace to the wicked is intentionally abrupt. It prevents the promise of release from being detached from the chapter's exposure of false confession and refusal to hear. Babylonian captivity is one problem; wickedness is not automatically removed by a change of address. Isaiah has just described peace as a river in the unrealized consequence of obedience. The final line keeps that moral dimension in place as the departure is announced. The passage ends neither in despair nor in uncomplicated celebration, but with redemption proclaimed and the meaning of peace carefully qualified.
Words to trace: LORD, rock, waters, Babylon, caused, Chaldeans
Verse-by-verse path
- Isaiah 48:20
Jeremiah gives the same order in his oracles on Babylon: “Remove out of the midst of Babylon” (50:8) and “Flee out of the midst of Babylon” (51:6, 45). “Voice of singing” is rinnah, the ringing shout of joy. The news is to be carried to the ends of the earth, where Cyrus came from.
- Isaiah 48:21
The verse joins two wilderness events, the rock struck at Horeb (Exodus 17:6) and the rock struck twice at Kadesh (Numbers 20:11). “Clave” is baqa, the verb for splitting the Red Sea (Exodus 14:16). Psalm 78:13-15 uses it for both: “He divided the sea... He clave the rocks in the wilderness.”
- Isaiah 48:22
The line recurs almost word for word at 57:21, “There is no peace, saith my God, to the wicked”, and many readers take the refrain as a divider marking chapters 40 to 66 into three blocks of nine: 40 to 48, 49 to 57, and 58 to 66. The last chapter ends on a harder note still (66:24).
Isaiah 48:20-22
King James Version20Go 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.
Questions to keep in mind while reading
