Writers of the Bible
Isaiah
c. 740–681 BC · Jerusalem aristocrat · counselor to four kings · prophet-poet of the Holy One
Hebrew יְשַׁעְיָהוּ (Yesha'yahu) — "the LORD is salvation" — his name was his message in miniature
Seven centuries before the cross, this counselor of kings described it so precisely that the church has called him the fifth evangelist.
The Books They Wrote (1)
The book opens over his signature: "The vision concerning Judah and Jerusalem that Isaiah son of Amoz saw" (1:1), spanning four reigns from Uzziah to Hezekiah — and 2 Chronicles 26:22 adds that Isaiah also wrote King Uzziah's official history, a court chronicler by trade. Many modern scholars assign chapters 40–66 to later writers, while the New Testament quotes freely from both halves as the words of one prophet — John 12:38–41 cites Isaiah 53 and Isaiah 6 side by side and says that Isaiah "saw Jesus' glory and spoke about him."
Life Story
The year King Uzziah died
Isaiah moved easily in the highest circles of Jerusalem — he walked into kings' presence unannounced, knew the court and its politics from the inside, and wrote the official history of King Uzziah (2 Chronicles 26:22). Jewish tradition even makes him kin to the royal house; Scripture simply shows us a man at home in palaces. Then, "in the year that King Uzziah died" — the year Judah's throne stood suddenly empty — he saw the throne that never stands empty: "I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple" (Isaiah 6:1). Seraphim called "Holy, holy, holy" until the doorposts shook, and the polished aristocrat came apart: "Woe to me! I am ruined! For I am a man of unclean lips." A seraph flew to him with a live coal from the altar and touched his mouth — "your guilt is taken away and your sin atoned for." Only then came the question, addressed to no one in particular: "Whom shall I send? And who will go for us?" And the man who had just been undone answered, "Here am I. Send me!" It is the most famous volunteering in the Bible — and God accepted it while warning him up front that the nation would be ever hearing but never understanding, until the cities lay ruined. Isaiah signed on for a lifetime of magnificent, mostly unheeded truth-telling.
A household of walking signs
Isaiah's ministry did not stop at his lips; it moved into his house. His wife is called simply "the prophetess." His sons carried sermons for names: Shear-Jashub, "a remnant will return" — judgment is coming, but not annihilation; and Maher-Shalal-Hash-Baz, the longest name in the Bible, "quick to the plunder, swift to the spoil" — Assyria is coming faster than you think. Every time the boys were called home for dinner, Jerusalem heard the word of the LORD. Isaiah understood the arrangement and embraced it: "Here am I, and the children the LORD has given me. We are signs and symbols in Israel from the LORD Almighty" (Isaiah 8:18). The costliest sign was his own body. When Judah's politicians looked to Egypt to save them from Assyria, God commanded Isaiah to go "stripped and barefoot" for three years, dressed like a prisoner of war, a living preview of what Egypt's own captives would soon look like (Isaiah 20). The aristocrat who had written royal chronicles became a public spectacle in the streets he had once graced. He had said "Send me" with no conditions attached; God took him at his word.
Counselor to four kings
Isaiah served through the reigns of Uzziah, Jotham, Ahaz, and Hezekiah — and the last two gave him his defining confrontations. When enemy armies massed against Jerusalem and the heart of King Ahaz shook "as the trees of the forest are shaken by the wind," Isaiah met him at the aqueduct with his son at his side and a blank check from God in his hand: ask any sign you want, deepest depths or highest heights. Ahaz declined with oily piety — he had already decided to buy Assyria's protection instead — and Isaiah answered that the Lord himself would give a sign anyway: "The virgin will conceive and give birth to a son, and will call him Immanuel" (Isaiah 7:14). A word flung at a faithless king became, seven centuries later, the church's Christmas text (Matthew 1:23). His finest hour came with Ahaz's son. In 701 BC Sennacherib of Assyria swallowed forty-six walled cities of Judah and sent his field commander to shout blasphemies at Jerusalem's wall. King Hezekiah spread the Assyrian ultimatum before the LORD in the temple, and Isaiah sent back one of Scripture's most defiant oracles: "He will not enter this city or shoot an arrow here… I will defend this city and save it" (Isaiah 37:33, 35). That night the angel of the LORD struck down a hundred and eighty-five thousand in the Assyrian camp, and the greatest army on earth went home without loosing an arrow. In those same years Isaiah carried both halves of God's word to Hezekiah's sickbed — "Put your house in order, because you are going to die," and then, before the king's tears had dried, fifteen added years, sealed by the shadow crawling backward ten steps on the stairway of Ahaz (Isaiah 38). The prophet who could not persuade one king to trust God lived to watch another king believe — and to watch God keep his word.
The fifth evangelist
Behind the public career stands the writer — and no Old Testament writer has ever been read the way Isaiah is read. The New Testament quotes him by name some twenty times, more than all the other writing prophets combined; his phrases scaffold Handel's Messiah; and from chapter 40 onward ("Comfort, comfort my people") his book turns from the ash of judgment to the most sustained vision of hope in the Old Testament. At its center stand the Servant Songs, and at their summit chapter 53: a servant "pierced for our transgressions," silent "as a sheep before its shearers," assigned a grave with the wicked and with the rich in his death, bearing "the sin of many." The early church did not read this as background material. When an Ethiopian official was found riding home puzzling over Isaiah 53 — "who is the prophet talking about, himself or someone else?" — Philip "began with that very passage of Scripture and told him the good news about Jesus" (Acts 8:35). Because chapters like 7, 9, 11, 35, 53, and 61 map so closely onto the Gospel story, the church came to call Isaiah "the fifth evangelist" — a preacher of Christ who happened to work seven hundred years before Bethlehem.
Sawn in two — death under Manasseh
Isaiah's public ministry ran some sixty years, from Uzziah's death past Sennacherib's retreat; 2 Chronicles 32:32 notes that Hezekiah's deeds, too, were recorded "in the vision of the prophet Isaiah son of Amoz." But Hezekiah's son Manasseh became the worst king Judah ever had, a man who "shed so much innocent blood that he filled Jerusalem from end to end" (2 Kings 21:16) — and about the old prophet's end, Scripture falls silent. Tradition does not. The Ascension of Isaiah, a second-century work, together with Jewish tradition in the Talmud, tells that Manasseh had the aged Isaiah sawn in two with a wood saw; since the early church, many readers have heard the echo of exactly that fate in Hebrews 11:37, where among the unnamed heroes of faith some "were sawed in two." It is tradition, not Scripture — but it is ancient, widespread, and grimly plausible under a king like Manasseh. His book outlived them all. When the Dead Sea Scrolls came out of the Qumran caves in 1947, the treasure of the find was a complete Isaiah scroll — twenty-four feet of leather copied a century and more before Jesus, the oldest complete book of the Bible in existence, and virtually identical to the text in your hands. The man was sawn apart, tradition says; the vision was not. Every line he wrote about the coming King was already on the shelf, waiting, when the King arrived.
Key Verse · Isaiah 6:8
“Then I heard the voice of the Lord saying, "Whom shall I send? And who will go for us?" And I said, "Here am I. Send me!"”
Pointing to Christ
No Old Testament book preaches Christ more fully. Isaiah gave the church the virgin's son who is "God with us" (7:14 → Matthew 1:23); the child on David's throne who bears four impossible names — "Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace" (9:6); and the Servant of chapter 53, "pierced for our transgressions… and by his wounds we are healed" — the one chapter the New Testament reaches for more than any other to explain the cross. And when Jesus stood up in the synagogue at Nazareth to announce his ministry, the scroll they handed him was Isaiah's: he read "The Spirit of the Sovereign LORD is on me, because the LORD has anointed me to proclaim good news to the poor" (61:1), rolled it shut, and said, "Today this scripture is fulfilled in your hearing" (Luke 4:21). Isaiah wrote the sermon; seven centuries later, the preacher arrived and claimed it.
Questions People Ask
Did one Isaiah write all 66 chapters?
This is the most debated question about the book. Chapters 40–66 speak to exiles in Babylon a century and a half after Isaiah's day and even name Cyrus, so since the 1800s many scholars have assigned them to one or more later writers ("Second Isaiah"). Christians who hold to one Isaiah reply that announcing the future is exactly what the book claims God does ("I make known the end from the beginning," 46:10); that no manuscript or ancient tradition ever knew Isaiah as anything but one book; and — weightiest — that the New Testament quotes both halves as one prophet: John 12:38–41 cites Isaiah 53 and Isaiah 6 back to back and says Isaiah "saw Jesus' glory." Sincere believers land differently on the details, and nothing in the book's inspiration or authority hangs on the outcome.
How could Isaiah describe the crucifixion seven hundred years early?
Isaiah 53 describes a servant "pierced for our transgressions," silent before his accusers "as a sheep before its shearers," executed with the wicked yet buried with the rich, whose death is an offering that justifies many — written centuries before crucifixion even existed as a Roman punishment. Christians answer plainly: this is prophecy, God publishing his rescue plan in advance, which is precisely what Isaiah says separates the true God from idols (41:21–23). And here the manuscripts close one escape route: the Great Isaiah Scroll from Qumran contains all of chapter 53 and was copied more than a century before Jesus was born, so the passage cannot be a Christian back-edit. The earliest church simply read it the way Philip did with the Ethiopian official — as "the good news about Jesus" (Acts 8:35).
Did Isaiah really name King Cyrus a century in advance?
Isaiah 44:28 and 45:1 name Cyrus — "my shepherd," the LORD's "anointed" — as the ruler who would order Jerusalem and the temple rebuilt; Cyrus of Persia did exactly that in 538 BC, roughly a hundred and fifty years after Isaiah's ministry. That stunning specificity is the main reason many scholars date those chapters later; believers in predictive prophecy point out that the book stakes God's very deity on announcing the future ("I make known the end from the beginning… I say, My purpose will stand," 46:10) and sets Cyrus's name on the table precisely as the proof. The Jewish historian Josephus even preserves a tradition that Cyrus was shown Isaiah's prophecy of himself and was moved to fulfill it. However one dates the chapters, the return happened exactly as written.
How did Isaiah die?
The Bible never says. He outlived Hezekiah's great deliverance and, by the traditional reckoning, lived into the reign of Manasseh — the king who "shed so much innocent blood that he filled Jerusalem from end to end" (2 Kings 21:16). Early tradition, preserved in the second-century Ascension of Isaiah and echoed in the Talmud and by church fathers, says Manasseh had him sawn in two; many readers believe Hebrews 11:37 ("they were sawed in two") alludes to his death. Treat it as what it is — a very old and widely attested tradition, not Scripture. What Scripture itself gives him is better than a death notice: a book that ends in new heavens and a new earth.
