When-was-Jeremiah-written
Short answer: Jeremiah 36 gives the clearest biblical anchor for the question. In the fourth year of Jehoiakim king of Judah, roughly 605 BC, Yahweh told Jeremiah to write on a scroll all the words he had spoken. Baruch wrote them, read them in the temple, and King Jehoiakim burned the scroll. Jeremiah then dictated the same words again, and many similar words were added. So the earliest written core of Jeremiah comes from about 605 BC, while the book continued to grow through the fall of Jerusalem and beyond. Jeremiah 1:1-3 introduces the whole collection as words that came over many years, which fits a book assembled from decades of preaching rather than written in a single sitting.
The date Jeremiah 36 gives us
Jeremiah 36 is unusually specific about time. The chapter opens by fixing the setting in the fourth year of Jehoiakim son of Josiah, king of Judah. That places the command to write in roughly 605 BC, the same year Jeremiah 25:1 dates to the fourth year of Jehoiakim and calls the first year of Nebuchadnezzar king of Babylon. Two chapters from different parts of the book point to the same window of history.
This is not a vague ancient setting. Babylonian power was rising, Egypt had just been broken at Carchemish, and Judah was about to become a vassal state. Jeremiah's message of coming judgment was no longer abstract. In that atmosphere he was told to put decades of prophetic preaching into written form, so that the words would not depend on his voice alone reaching the hearers.
The fourth year of Jehoiakim therefore functions as the date for the first written scroll, not necessarily the date of the final book. Readers sometimes treat the two as the same thing. Jeremiah 36 itself already shows otherwise, since the scroll is destroyed and then replaced with more material, a sign that the written collection was still open and growing.
What the scroll of Jeremiah 36 actually contained
Jeremiah 36:2 records the command to take a scroll and write on it all the words spoken against Israel, Judah, and the nations from the days of Josiah until that day. That is a wide span. Josiah reigned from about 640 to 609 BC, so the command covers roughly two decades of prophetic ministry already delivered orally before anything was written down.
This matters for the question of when Jeremiah was written. The scroll was not a fresh revelation composed from nothing in 605 BC. It was a written collection of messages already preached. The chapter describes a deliberate transition from spoken word to written word, which is exactly what the command means in context.
Because the chapter summarises rather than lists contents, we cannot say with certainty which of the surviving chapters stood on that first scroll. Many students of the book think material from the earlier reigns, including warnings now found in the opening chapters and the judgment sections, formed part of it. That is a reasonable inference, not something the text states outright.
Baruch, the scribe, and the public reading
Jeremiah 36 names Baruch son of Neriah as the one who wrote at Jeremiah's dictation. Baruch then carried the scroll into the temple and read it before the people on a fast day, and later before the officials. When the officials heard the words, they recognised their seriousness and arranged for the king to hear them, warning Baruch and Jeremiah to hide.
The scene shows how the book came to exist in stages. A prophet who could not go to the temple himself, for reasons the chapter gives, used a scribe and a scroll to reach an audience he could no longer address in person. The written text was a means of proclamation, not a private literary project.
Baruch's role is one reason many Christians speak of Jeremiah as a book shaped by a prophet and his scribe. It also explains the shift in style across the book. Some passages read as poetic oracles, others as prose narrative about Jeremiah's life. A scribe recording, arranging, and supplementing the prophet's words fits that variety naturally.
The burning of the scroll and the second writing
King Jehoiakim had the scroll read to him piece by piece as he sat by a fire. As each section was read, he cut it off and threw it into the flames until the whole scroll was burned. He and his servants showed no fear and did not tear their garments, a detail the chapter notes pointedly. The reaction tells us more about the king than about the date, but it confirms the scroll was a real physical object.
Jeremiah was then commanded to write the words again, and he did, adding many similar words. This second scroll is the one that stands behind the book we have. Whatever the first scroll contained, the replacement was larger, not smaller. Persecution did not shrink the written word; it expanded it.
Anyone asking when Jeremiah was written has to reckon with this episode. Part of the book was written around 605 BC, destroyed, and rewritten soon after. The rewritten version already contained more than the first. The book was a living collection from its earliest written stage.
Indicators that the book was finished later
Several passages point beyond 605 BC and even beyond the fall of Jerusalem in 586 BC. Jeremiah 51:59-64 describes a command given to Seraiah in the fourth year of Zedekiah, decades after Jehoiakim's fourth year. That places written material from a later reign inside the same book. The final chapters narrate events after Jerusalem fell, including Jeremiah's forced departure to Egypt.
Jeremiah 1:1-3 frames the whole collection as words that came in the days of Josiah, then Jehoiakim, then Zedekiah, down to the exile of Jerusalem in the fifth month. A book with that span cannot have been completed in 605 BC. The opening verses themselves tell the reader the collection covers a long period and ends in exile.
Daniel 9:1-2 gives an outside witness that Jeremiah was already recognised as written Scripture by the time Daniel was reading it in the first year of Darius the Mede. Daniel understood from the books, meaning Jeremiah's written prophecy, that the seventy years were nearly complete. By that point the scrolls of Jeremiah were being studied as authoritative text, not recited as recent preaching.
How the book likely grew in stages
The most careful way to describe it is this. Jeremiah's preaching began under Josiah around 627 BC. Around 605 BC much of it was written down in a scroll that was burned and rewritten with additions. Further oracles were written under Zedekiah, as Jeremiah 51:59-64 shows. After the fall of Jerusalem, narratives about Jeremiah's suffering and the final events were added, and the whole collection was arranged into the book we now have.
This staged process is not a problem for faith. It is the same pattern seen in other prophetic books, where oracles delivered across years are gathered and ordered later. The book itself tells us this happened. Honest readers should say plainly that the precise timing of each chapter is not always stated, and that scholars who accept the book's truthfulness still differ on details.
What the text does establish is the starting point. A written Jeremiah existed by about 605 BC, produced under the prophet's direction by a named scribe, and it was publicly read and officially destroyed. Everything else about the book's growth is best described with appropriate restraint.
Why the date matters for reading Jeremiah
Knowing when Jeremiah was written changes how the book reads. The early chapters belong to a time when reform under Josiah gave real hope and judgment had not yet fallen. The middle chapters belong to Jehoiakim's reign, when the king burned the scroll and Babylon advanced. The later chapters belong to the siege, the fall, and the aftermath, when the promised judgment arrived exactly as spoken.
This also strengthens confidence in the message. Jeremiah warned of a foe from the north and of seventy years of exile. The narrative shows those warnings fulfilled within the same book, by people who lived through them. A collection written across decades, by a prophet who watched his own words come true, is a different kind of witness from a document composed long afterwards with hindsight.
For readers today, the practical effect is to read Jeremiah as a sustained testimony rather than a single dated letter. The date of the first scroll tells us when the writing began. The shape of the finished book tells us it was completed later, for people who needed the words in writing.
Biblical fidelity check
Jeremiah 36 establishes several things clearly. It states that Yahweh commanded Jeremiah to write on a scroll, that Baruch wrote at his dictation, that the scroll was read publicly, that Jehoiakim burned it, and that Jeremiah dictated it again with many similar words added. It dates the command to the fourth year of Jehoiakim, about 605 BC. Jeremiah 1:1-3 establishes that the book as a whole spans the reigns of Josiah, Jehoiakim, and Zedekiah down to the exile.
What the passage does not establish is the date of every chapter or the exact contents of the first scroll. It never lists which oracles were on it. It does not say when the final arrangement was completed, and it names no editor beyond Baruch. A common misreading treats Jeremiah 36 as proof that the entire book was written in one sitting in 605 BC. That reading contradicts the chapter itself, which shows the scroll burned, rewritten, and expanded, and it contradicts Jeremiah 1:1-3, which covers a far longer period. The text gives an anchor, not a single date for everything.

Several related studies help place this chapter in its wider setting. The opening verses of the book set the long timeframe in which the scroll was produced, and they are worth reading alongside it: Why trust the Bible when it was written by humans? A Biblical Guide. Jeremiah's own experience of waiting on God's timing connects to Bible Verses About Faith: Trusting God When You Cannot See the Outcome. The exiles who received his later letters needed endurance, which is the theme of Bible Verses About Hope: Christian Hope When Life Feels Heavy. And Daniel, who read Jeremiah's scrolls and prayed over the seventy years, is studied in Daniel 1: Faithfulness in Babylon's Court.
Frequently asked questions
In what year was Jeremiah first written down?
Jeremiah 36:1 places the command to write in the fourth year of Jehoiakim son of Josiah, king of Judah, which works out to roughly 605 BC. Jeremiah 25:1 dates the same year and identifies it as the first year of Nebuchadnezzar king of Babylon. That scroll was read publicly, burned by the king, and rewritten with additional words, so 605 BC marks the beginning of the written book rather than its completion.
Was the whole book of Jeremiah written at one time?
No. Jeremiah 1:1-3 describes words that came across the reigns of Josiah, Jehoiakim, and Zedekiah, ending with the exile of Jerusalem. Jeremiah 51:59-64 records a command given in the fourth year of Zedekiah, later than the scroll of chapter 36. The final chapters narrate events after the city fell. The book was gathered and arranged over decades, and faithful readers differ on the details of that process.
Does the burned scroll mean part of Jeremiah was lost?
The text says the words were written again, with many similar words added, so nothing was permanently lost. Jehoiakim destroyed one copy, but the prophetic word continued and grew. If anything, the episode shows the opposite of loss: what the king tried to erase was restored in fuller form. The book we have stands in the line of that rewritten scroll.
