Isaiah

← Encyclopedia

Isaiah is one of the major prophetic books of the Hebrew Bible, sixty-six chapters of oracle, vision, and poetry placed first among the books named for the writing prophets. Its opening verse attributes the whole to Isaiah son of Amoz, a prophet active in Jerusalem in the eighth century BCE, through the reigns of several kings of Judah. The book ranges from threats of judgment against Judah and its neighbors to some of the most exalted hope-language in the canon — the wolf lying down with the lamb, swords beaten into plowshares, a servant who suffers on behalf of others.

The prophet in Jerusalem

The man named in the heading stands inside a precise historical horizon. The superscription places his vision under Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah, and the dramatic dating of his call — the year King Uzziah died, around 740 BCE — fixes the start of a ministry that the tradition stretches across some four decades. He moves at the center of the kingdom rather than at its margins: a counselor with access to the throne, addressing monarchs in moments of national peril. His wife is called the prophetess, and his two sons carry names that are themselves oracles. Shear-jashub means a remnant shall return; Maher-shalal-hash-baz, swift to the spoil and speedy to the plunder, is hung on the child as a sign that Assyria will strip Damascus and Samaria before the boy can speak. In Isaiah the word is not only spoken; it is named into a household and walked through the streets.

Two crises define the Jerusalem of the early chapters. In the first, the Syro-Ephraimite war, a coalition of Damascus and the northern kingdom presses Judah to join a revolt against Assyria; the prophet meets the frightened King Ahaz and presses on him a single counsel — trust, hold still, do not bargain the future away to empires. In the second, a generation later, the Assyrian king Sennacherib marches on Jerusalem in 701 BCE and shuts up Hezekiah, in the book’s own image, like a bird in a cage. Here the prophet’s counsel hardens into promise: the city will not fall, the Assyrian will turn back the way he came. The siege lifts, and the deliverance of Zion becomes one of the load-bearing memories of the whole tradition — the conviction that the holy city, however threatened, is finally inviolable.

The throne and the call

At the book’s hinge stands a vision that later religion never let go of. In the year of Uzziah’s death the prophet sees the Lord seated on a high and lofty throne, the hem of the robe filling the temple, and above it the seraphim — burning ones, six-winged — who cover their faces and feet and cry to one another a threefold sanctus: holy, holy, holy is the Lord of hosts; the whole earth is full of his glory. The thresholds shake, the house fills with smoke, and the seer, undone by his own uncleanness, is purified when a seraph touches a live coal from the altar to his lips. Only then comes the commission — Whom shall I send? — and the answer, Here am I; send me.

The scene gathers several of the book’s deepest currents into one image. It is a heavenly liturgy, and its triple cry passed into the worship of both synagogue and church, surfacing in the Qedushah of Jewish prayer and in the Sanctus of the Christian Mass. It is also a vision of overwhelming holiness against which the human is measured and found wanting, then remade — a pattern that shaped the throne-mysticism running forward through Ezekiel, the apocalypse of Daniel, and the visionary literature of Second Temple Judaism. And it carries a hard charge: the prophet is sent to a people who will hear and not understand, until cities lie waste and the land is desolate, with only a stump — a holy seed — left standing. Hope and devastation are spoken in the same breath.

Immanuel, the shoot, and the peaceable kingdom

From the war-counsel given to Ahaz comes the book’s most contested sign. Refusing to ask for a sign, the king is given one anyway: a young woman is with child and shall bear a son, and shall call his name Immanuel, meaning God-with-us; before the child knows good from evil the two threatening kings will be gone. In its first setting the oracle is a timetable for a near deliverance. Read forward, Immanuel becomes one of the great messianic names, and the New Testament gospel of Matthew binds it directly to the birth of Jesus.

Around this sign cluster the dynastic oracles that made Isaiah the seedbed of messianic hope. A child is born on whom the government rests, named Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace, set to reign on the throne of David without end. A shoot grows from the stump of Jesse — David’s father — and on him the spirit of the Lord rests; he judges the poor with righteousness, and in his days the wolf lodges with the lamb, the leopard with the kid, a little child leading them, and the whole earth is full of the knowledge of the Lord. Earlier still comes the vision of the mountain of the Lord’s house raised above the hills, nations streaming to it for instruction, beating their swords into plowshares and their spears into pruning hooks, learning war no more. These images gave later ages a vocabulary for the world as it might be — a kingdom of peace under a just anointed one — and they remained generative far beyond their first century, feeding the messianic expectation of Second Temple Judaism and the prophetic-messianic currents of much later eras.

The oracles against the nations

Between the early Jerusalem material and the visions stands a long sequence of oracles aimed outward — against Babylon, Assyria, Philistia, Moab, Damascus, Cush, Egypt, Tyre, and others, with a great apocalyptic finale in which the whole earth is laid waste, the cosmos staggers like a drunkard, and the Lord of hosts reigns on Mount Zion. The taunt-song over the king of Babylon, with its falling Day Star, son of the Dawn — Lucifer in the Latin tradition — supplied later demonology with one of its founding images of a heavenly power cast down. The function of the sequence is theological as much as political: the God of a small kingdom is declared sovereign over every empire, his purpose running through and beneath the rise and fall of the great powers. That claim becomes the engine of the chapters that follow.

Comfort, the Servant, and the new creation

At chapter 40 the book turns, and the change of voice is unmistakable — comfort, comfort my people, the opening word of the second movement. The horizon has moved a century and a half. Babylon has fallen or is falling; the exile is ending; a herald cries in the wilderness to prepare the way of the Lord. The Persian king Cyrus is named outright and called the Lord’s anointed — in Hebrew his mashiah, the only foreigner in scripture to wear that title — raised up to break Babylon and send the captives home. These chapters press a fierce monotheism harder than anywhere else in the canon: the idols are nothing, fashioned from the same wood that warms a fire and bakes bread; there is no god beside the one who forms light and creates darkness, makes peace and creates calamity.

Embedded in this Book of Consolation are four passages that modern scholarship, following Bernhard Duhm, set apart as the Servant Songs. In them a figure called the Lord’s servant is appointed to bring justice to the nations, formed in the womb for his task, given a tongue to sustain the weary and a back to the smiters — and, in the fourth and longest, despised and rejected, a man of sorrows, wounded for the transgressions of others, led like a lamb to the slaughter, making his life an offering for sin and bearing the iniquity of many. Who the servant is has been argued since antiquity. One reading hears the nation Israel itself, suffering among the empires and vindicated; another hears an individual — the prophet, a coming deliverer, or a figure the text holds deliberately open. The fourth song became the single most consequential passage in the book’s afterlife: early Christianity read the wounded servant of chapter 53 as the crucified Jesus, and the New Testament returns to it again and again to make sense of a messiah who dies.

The final chapters move into the restored community back in the land and rise, at the end, to a vision of cosmic renewal. The Lord creates new heavens and a new earth; the former things are not remembered; Jerusalem is made a joy and her people a rejoicing; the wolf and the lamb feed together, and none hurt or destroy in all the holy mountain. That promise of a remade creation passed directly into Jewish and Christian eschatology and gave the New Testament apocalypse its closing image of a new heaven and a new earth.

The three-Isaiah question

For most of its history the book was read as the unified work of that one eighth-century prophet. Since the late eighteenth century critical scholarship has read it otherwise. The chapters fall into sections that differ markedly in tone, setting, and historical horizon: an early body of material rooted in eighth-century Jerusalem; a stretch addressed to exiles in Babylon, presupposing that the city has already fallen and that release is near; and later chapters concerned with a restored community back in the land. The conventional names for these layers are First, Second, and Third Isaiah, and the prevailing view holds that the book grew over more than two centuries, gathered under the prophet’s name. How sharply to divide it, and how much one editorial vision shapes the whole, remains argued.

The division has a documented pedigree. In 1775 the German scholar Johann Christoph Döderlein argued that chapters 40 through 66 came from a hand later than the eighth-century prophet — an anonymous voice of the exile who would come to be called Deutero-Isaiah, the Second Isaiah. More than a century later Bernhard Duhm, in his 1892 commentary, refined the picture into the three-part scheme still taught today: First Isaiah (chapters 1–39) from the eighth century; Deutero-Isaiah (40–55), the exilic Book of Consolation; and Trito-Isaiah (56–66), the post-exilic chapters of a restored Jerusalem. It was Duhm, too, who first isolated the four Servant Songs as a distinct strand within the Second Isaiah material. His scheme dominated twentieth-century study; more recent scholarship has both pressed the divisions finer and pushed back the other way, tracing the threads of vocabulary, image, and theme — the highway in the wilderness, the glory of the Lord, the holy mountain — that knit the sixty-six chapters into a single composed book. Whether read as the voice of one seer or as a tradition layered across generations, the question of Isaiah’s authorship is itself one of the foundation stones of modern biblical criticism.

The Great Isaiah Scroll

Among the Dead Sea Scrolls recovered from Qumran Cave 1 in 1947, one manuscript — designated 1QIsaa, the Great Isaiah Scroll — preserves the entire Book of Isaiah from beginning to end, lacking only small damaged portions. Around twenty-four feet of stitched parchment in fifty-four columns, copied around 125 BCE, it is the oldest substantially complete copy of any book of the Hebrew Bible, roughly a thousand years older than the medieval manuscripts that had been the oldest Hebrew witnesses before the scrolls came to light. Set beside the Masoretic text transmitted through the following millennium, it shows more than two and a half thousand variants — but the overwhelming majority are matters of spelling and scribal habit rather than substance, and the scroll stands remarkably close to the text that later generations received. The find anchored debate about how stable the wording of scripture had been across that long silence, and it sits among the oldest substantial witnesses to any book of the Hebrew Bible. The scroll is now housed in the Shrine of the Book at the Israel Museum in Jerusalem.

Reception and afterlife

The book’s reach into later religion is hard to overstate. Jewish tradition kept it as the foremost of the Latter Prophets and drew its haftarot — the prophetic readings paired with the Torah — heavily from its consolations, and the seven haftarot of comfort read between the fast of the Ninth of Av and the New Year are taken almost entirely from Second Isaiah. The threefold sanctus of the throne vision became a fixed point of the synagogue liturgy. Early Christianity read the book as prophecy of Jesus to a degree matched by no other Old Testament book: the child called Immanuel, the shoot from the stump of Jesse, the voice crying in the wilderness, and above all the servant of the later chapters, wounded for the transgressions of others, were taken as foretelling the passion. The New Testament quotes Isaiah more than almost any other scripture; the gospel of Luke opens Jesus’s public ministry with him reading the Spirit-anointed mission of Isaiah 61 in the Nazareth synagogue and declaring it fulfilled. For this density of fulfilled prophecy the church came to call Isaiah a kind of fifth gospel, and its language saturates Christian hymn and oratorio down to Handel’s Messiah. The same chapters that fed Christianity remained, within Judaism, the great well of consolation and the promise of return — read there not as a forecast of a single life but as the assurance that exile is not the last word.

Whether read as the voice of a single seer or as a tradition layered across generations, Isaiah holds together threat and comfort in the same book — the ruin foretold and the restoration promised — and it is that double note, more than any single oracle, that later readers kept returning to.
