The Bible was written over a span of roughly 1,500 years by more than 40 different authors across three continents. From ancient Hebrew poetry composed in the deserts of the Near East to Greek letters penned in Roman prisons, the 66 books of the Bible represent one of the most remarkable literary collections in human history. Here is what the historical evidence shows about when those books were written — including where scholars agree and where honest uncertainty still remains.

The Short Answer: 1,500 Years, 40+ Authors, 3 Languages

The Bible was not written all at once. It is a collection of 66 books (39 in the Old Testament and 27 in the New Testament) composed over approximately 1,500 years. The earliest portions may date to around 1400 BC according to traditional dating, while the last book, Revelation, was likely written around 95 AD.

These books were written by more than 40 different authors, including kings, shepherds, fishermen, tax collectors, a physician, prophets, and a tentmaker. They wrote in three languages: Hebrew (most of the Old Testament), Aramaic (portions of Daniel and Ezra), and Greek (the entire New Testament). The writing took place across three continents: Asia, Africa, and Europe.

Despite this extraordinary diversity of authorship and time span, Christians have historically understood the Bible as a unified work. As the apostle Paul wrote:

All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness.– 2 Timothy 3:16 (ESV)

Knowing when each book was written brings it to life — you begin to hear a prophet writing under siege, or a shepherd composing psalms in the wilderness. Where conservative and critical scholars read the evidence differently, both perspectives are included here.

When Was the Old Testament Written?

The Old Testament (called the Tanakh in Judaism) contains 39 books that were composed over a period of roughly 1,000 years. Dating these texts is complex because many books draw on earlier oral traditions, and some were edited or compiled over several generations. Here is a look at the major sections and their approximate dates.

The Torah (Pentateuch): ~1400 BC or ~950–500 BC

The first five books of the Bible — Genesis, Exodus, Leviticus, Numbers, and Deuteronomy — are traditionally attributed to Moses. If Moses wrote them during or shortly after the Exodus from Egypt, the traditional date of composition would fall around 1400 BC (using the early Exodus date) or around 1250 BC (using the later date favored by many archaeologists).

Critical scholars, following the Documentary Hypothesis developed in the 18th and 19th centuries, propose that the Torah was compiled from multiple written sources over several centuries. In this view, the earliest source (often called J or the Yahwist) may date to around 950 BC during the early monarchy, while the final form of the text was likely completed during or shortly after the Babylonian exile, around 500 BC.

Whatever your view, both sides agree: the Torah contains very old material. Even scholars who date the final compilation late recognize that much of the Pentateuch reflects traditions from the second millennium BC. The Song of the Sea in Exodus 15, for example, is widely regarded as one of the oldest passages in the Bible based on its archaic Hebrew grammar.

Historical Books: ~1000–400 BC

The historical books — Joshua, Judges, Ruth, 1–2 Samuel, 1–2 Kings, 1–2 Chronicles, Ezra, Nehemiah, and Esther — cover Israel’s history from the conquest of Canaan to the return from Babylonian exile. They were composed and compiled over roughly 600 years.

Joshua and Judges likely contain material from as early as 1000 BC, though they reached their current form later. The books of Samuel and Kings draw on court records, prophetic accounts, and other sources that may date to the 10th–7th centuries BC. The so-called Deuteronomistic History (Joshua through 2 Kings) was probably compiled in its final form during the exile, around 550 BC.

Chronicles, Ezra, and Nehemiah are among the latest Old Testament historical books, likely composed between 450 and 400 BC. Esther is also generally dated to the 5th or 4th century BC.

Poetry and Wisdom Literature: ~1000–300 BC (Job Possibly the Oldest)

The poetic and wisdom books include Job, Psalms, Proverbs, Ecclesiastes, and Song of Solomon. These books are especially hard to date because wisdom literature rarely names kings or describes specific historical events.

Job is sometimes considered the oldest book in the Bible. The story’s patriarchal setting, its lack of references to the Mosaic Law or Israelite history, and its archaic language have led some scholars to date its composition as early as 2000–1500 BC. Others place it later, in the 6th or 5th century BC, arguing that its sophisticated theology reflects a more developed literary tradition. The honest answer is that no one knows for certain when Job was written.

The Psalms were composed over several centuries. Some psalms attributed to David may originate around 1000 BC, while others (such as Psalm 137, which references the Babylonian exile) were clearly written in the 6th century BC. The Psalter as a collected book probably reached its final form around 400–300 BC.

Proverbs is attributed to Solomon (reigned ~970–930 BC), though the text itself notes that some sections were compiled later (Proverbs 25:1 credits the “men of Hezekiah” around 700 BC). Ecclesiastes and Song of Solomon are traditionally linked to Solomon as well, though many scholars date Ecclesiastes to the 3rd century BC based on its language and philosophical themes.

The Prophets: ~850–400 BC

The prophetic books span roughly 450 years of Israelite history. The earliest writing prophets likely include Obadiah and Joel, though their dates are debated. Amos and Hosea are generally dated to the mid-8th century BC (around 760–720 BC), making them among the earliest prophetic writings whose dates are widely agreed upon.

Isaiah presents a complex dating question. Chapters 1–39 are widely attributed to the historical Isaiah, who prophesied in Jerusalem around 740–700 BC. Chapters 40–66, however, address the Babylonian exile and return, leading many scholars to attribute them to one or more later authors writing in the 6th century BC. Conservative scholars maintain the unity of Isaiah under a single author, viewing the later chapters as predictive prophecy.

Jeremiah and Ezekiel were active during the fall of Jerusalem and the Babylonian exile (roughly 626–570 BC). Daniel is dated to the 6th century BC by traditional scholars and to around 165 BC by critical scholars who view its detailed prophecies about the Greek period as written after the events.

The post-exilic prophets — Haggai, Zechariah, and Malachi — wrote after the return from Babylon. Haggai and Zechariah date to around 520 BC, while Malachi is generally placed around 430 BC.

The Last Old Testament Book and the Intertestamental Gap

Malachi, written around 430 BC, is typically regarded as the last book of the Old Testament to be composed. After Malachi, roughly 400 years passed with no new Scripture added to the Hebrew canon — before the first New Testament documents appeared.

This period was not actually silent. Important Jewish texts were written during this time, including the books of the Apocrypha (such as 1 Maccabees, Sirach, and Wisdom of Solomon), the Dead Sea Scrolls sectarian literature, and other works. However, these texts were not included in the Protestant Old Testament canon, though some are recognized as canonical or deuterocanonical by Catholic and Orthodox traditions.

When Was the New Testament Written?

The 27 books of the New Testament were all written in Greek within a span of roughly 50 years, from about 45 AD to 95 AD. That is a remarkably compact window — much of the New Testament was written within living memory of the Resurrection. Most scholars agree on the general sequence and approximate dates, though specific years are debated.

Luke, the physician and companion of Paul, described the careful process behind the writing of the Gospel accounts:

Inasmuch as many have undertaken to compile a narrative of the things that have been accomplished among us, just as those who from the beginning were eyewitnesses and ministers of the word have delivered them to us, it seemed good to me also, having followed all things closely for some time past, to write an orderly account for you, most excellent Theophilus.– Luke 1:1-4 (ESV)

James and Paul’s Letters: The Earliest New Testament Writings (~45–67 AD)

The earliest New Testament book may be the Epistle of James. If written by James the brother of Jesus (who was martyred in 62 AD), it is often dated to around 45–50 AD, which would make it the first New Testament document. Some scholars date it later, to the 60s or even later, but the letter’s Jewish character and lack of references to the Gentile controversy support an early date.

Of all the New Testament writings, Paul’s letters have the most firmly established dates. His first letter to the Thessalonians (1 Thessalonians) is widely dated to around 49–51 AD, making it one of the oldest surviving Christian documents. Paul continued writing letters to churches and individuals throughout his missionary career.

Galatians is dated to around 48–55 AD. The Corinthian correspondence (1 and 2 Corinthians) falls around 53–56 AD. Romans, perhaps Paul’s most theologically developed letter, was written around 57 AD. The Prison Epistles (Ephesians, Philippians, Colossians, and Philemon) are generally dated to the early 60s AD, during Paul’s imprisonment in Rome. The Pastoral Epistles (1 and 2 Timothy, Titus) are traditionally dated to 63–67 AD near the end of Paul’s life, though some scholars attribute them to a later follower of Paul.

The Four Gospels: ~65–100 AD

The Gospels were not the first New Testament books written, despite appearing first in the canonical order. Most scholars believe the Gospel of Mark was written first, around 65–70 AD. Mark’s Gospel is the shortest, and the other Synoptic Gospels (Matthew and Luke) appear to draw on it as a source.

Matthew is generally dated to around 70–85 AD. It was written for a Jewish-Christian audience and contains extensive quotations from the Old Testament. Some conservative scholars argue for a pre-70 AD date, noting that Jesus’ prophecy about the temple’s destruction in Matthew 24 reads as a genuine prediction rather than a description after the fact.

Luke is typically dated to around 75–85 AD. Luke was a careful historian who wrote both his Gospel and the book of Acts as a two-volume work addressed to Theophilus. Some scholars argue for an early date for Luke-Acts (before 62 AD) because Acts ends abruptly without mentioning Paul’s death, the fall of Jerusalem, or other major events that occurred in the mid-60s.

The Gospel of John is the latest of the four Gospels, generally dated to around 90–100 AD. It is distinct in style and structure from the Synoptic Gospels and includes material not found in the others, such as the raising of Lazarus and the extended farewell discourse. Tradition attributes it to the apostle John, writing from Ephesus in his old age.

Acts of the Apostles: ~62–85 AD

Acts is the sequel to Luke’s Gospel and covers the history of the early church from the ascension of Jesus to Paul’s imprisonment in Rome. Its date depends largely on the date assigned to Luke’s Gospel. Those who favor an early date for Luke place Acts around 62 AD. Those who date Luke later place Acts in the late 70s or early 80s AD.

The abrupt ending of Acts — with Paul under house arrest in Rome, awaiting trial — remains one of the most debated questions in New Testament dating. If Luke wrote after Paul’s death (traditionally around 64–67 AD), why not mention it? This has led some scholars to argue that Acts was completed before these events occurred, pushing the date of Luke-Acts back to the early 60s.

Revelation: ~95 AD — The Last Book Written

The book of Revelation is widely regarded as the last New Testament book to be written. The early church father Irenaeus (writing around 180 AD) stated that John received the vision “toward the end of Domitian’s reign,” which would place it around 95–96 AD. Domitian ruled as Roman emperor from 81 to 96 AD.

A minority of scholars argue for an earlier date, around 65–69 AD during Nero’s reign, based on internal clues such as the reference to the temple in Revelation 11 (suggesting it was still standing) and the identification of the “seven kings” in Revelation 17. However, the late date under Domitian remains the majority view in both conservative and critical scholarship.

With Revelation’s composition around 95 AD, the New Testament was complete. The entire collection of 27 books had been written within roughly 50 years of Jesus’ crucifixion.

How Was the Bible Preserved?

One of the most common questions about the Bible is how we can trust that the text we read today matches what was originally written. After all, the originals (called autographs) no longer exist. What we have are copies of copies. So how reliable is the transmission?

The Dead Sea Scrolls: A Game-Changing Discovery

In 1947, a Bedouin shepherd stumbled upon clay jars in caves near the Dead Sea at Qumran. Inside were scrolls that had been hidden for nearly 2,000 years. The Dead Sea Scrolls contain portions of every Old Testament book except Esther, and they date from the 3rd century BC to the 1st century AD.

The most famous discovery was the Great Isaiah Scroll (1QIsa^a), a nearly complete copy of Isaiah dated to around 125 BC. When scholars compared it with the Masoretic Text (the Hebrew text used for modern translations, finalized around 900 AD), they found the two texts to be remarkably similar. Over a gap of more than 1,000 years, the text had been transmitted with extraordinary accuracy. There were minor spelling differences and a handful of variant readings, but no significant theological differences.

Papyrus 52 and Early New Testament Manuscripts

The earliest known fragment of the New Testament is Papyrus 52 (P52), a small piece of papyrus containing portions of John 18:31–33 and 18:37–38. It is dated to approximately 125 AD, only about 25–30 years after the Gospel of John was written. This fragment demonstrates that John’s Gospel was being copied and circulated in Egypt within a generation of its composition.

The New Testament is the best-attested document from the ancient world. There are over 5,800 Greek manuscripts, more than 10,000 Latin manuscripts, and thousands more in other ancient languages. By comparison, most classical Greek and Roman works survive in fewer than 20 manuscripts, with the earliest copies dating centuries after the originals. The sheer volume of New Testament manuscripts, combined with their early dates, gives scholars a strong basis for reconstructing the original text.

Scribal Practices and Transmission

Jewish scribes took the copying of Scripture with extraordinary seriousness. The Talmud records detailed rules for copying Torah scrolls: scribes had to use specially prepared parchment and ink, could not write from memory, had to pronounce each word aloud before writing it, and had to count the letters in each section to verify accuracy. If a single error was found, the entire scroll could be discarded.

These meticulous practices help explain why the Dead Sea Scrolls, copied centuries before the Masoretic scribes, match the later text so closely. The scribes were not casual copyists; they were guardians of a sacred text, and their methods were designed to prevent exactly the kind of corruption that skeptics often assume must have occurred.

How Was the Bible Put Together? The Formation of the Canon

The Bible did not arrive as a single volume dropped from heaven. The process of recognizing which books belonged in the canon was gradual, spanning several centuries. Here are the key milestones.

The Septuagint (~250–100 BC)

The Septuagint (often abbreviated LXX) is a Greek translation of the Hebrew Scriptures produced in Alexandria, Egypt, beginning around 250 BC. It was created for Greek-speaking Jews who could no longer read Hebrew fluently. The Septuagint is significant because it was the Bible used by the early church — most Old Testament quotations in the New Testament come from the Septuagint rather than the Hebrew text.

The Septuagint included some books not found in the Hebrew canon, which later became the subject of debate between Protestants (who follow the Hebrew canon) and Catholics (who include several of these additional books as deuterocanonical).

The Council of Jamnia and the Hebrew Canon (~90 AD)

According to a widely cited tradition, Jewish rabbis gathered at Jamnia (Yavneh) around 90 AD and formally settled the boundaries of the Hebrew canon. More recent scholarship has questioned whether Jamnia was a formal council at all. It may have been more of an academy where ongoing discussions about certain disputed books (such as Ecclesiastes and Song of Solomon) took place. Nevertheless, by the end of the 1st century AD, the Hebrew canon of 39 books was broadly recognized within Judaism.

The Muratorian Fragment (~170 AD)

The Muratorian Fragment is the oldest known list of New Testament books, dated to approximately 170 AD. It includes most of the books in the current New Testament canon, including the four Gospels, Acts, all of Paul’s letters, Jude, 1–2 John, and Revelation. It omits Hebrews, James, 1–2 Peter, and 3 John, which suggests these books were still being discussed in some regions.

Athanasius’s Easter Letter (367 AD)

In 367 AD, Athanasius, the Bishop of Alexandria, wrote his annual Easter letter to the churches under his authority. In it, he listed all 27 books of the New Testament exactly as we have them today. This is the earliest known document to list the complete New Testament canon without any additions or omissions. Athanasius did not create the canon; he recognized what the churches had already been using for generations.

The Councils of Hippo (393 AD) and Carthage (397 AD)

The regional councils of Hippo (393 AD) and Carthage (397 AD) formally affirmed the 27-book New Testament canon that Athanasius had listed. These councils also affirmed the Old Testament canon, including the deuterocanonical books that remain part of the Catholic Bible. It is important to note that these councils did not impose the canon by top-down authority. Rather, they ratified what had already emerged through centuries of widespread use, theological reflection, and consensus among churches across the Roman Empire.

The apostle Peter, writing about Paul’s letters, already treated them as Scripture alongside the Old Testament:

And count the patience of our Lord as salvation, just as our beloved brother Paul also wrote to you according to the wisdom given him, as he does in all his letters when he speaks in them of these matters. There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures.– 2 Peter 3:15-16 (ESV)

Frequently Asked Questions About When the Bible Was Written

What Is the Oldest Book in the Bible?

There is no definitive answer, and it depends on how you define “oldest.” Job is a strong candidate based on its patriarchal setting and archaic language, with some scholars dating its composition to as early as 2000–1500 BC. However, others date Job much later. Some of the earliest psalms attributed to Moses (such as Psalm 90) and the Song of the Sea (Exodus 15) may contain material that is among the oldest in the Bible. The oldest complete book to reach its current form is likely one of the books of the Torah, though whether that happened in the 15th century BC (traditional view) or the 6th–5th century BC (critical view) depends on one’s scholarly framework.

How Long Did It Take to Write the Entire Bible?

From the earliest written portions to the last, the Bible took approximately 1,500 years to complete. If we use the traditional date for Moses (around 1400 BC) as the starting point and the writing of Revelation (around 95 AD) as the endpoint, the span is roughly 1,500 years. Using critical dates that place the earliest written sources around 950 BC, the timeframe shrinks to about 1,050 years. Either way, no other religious text in widespread use today was composed over such a long period by so many different authors.

Who Decided Which Books Belong in the Bible?

No single person or council decided the canon in a top-down fashion. The process was organic and gradual. Books were accepted based on several criteria: apostolic authorship or connection (was it written by an apostle or close associate?), consistency with accepted doctrine, widespread use in churches, and recognition by church leaders. The councils of Hippo (393) and Carthage (397) formally ratified what the broader church had already recognized over the preceding centuries. The canon was not imposed; it was recognized.

Are There Lost Books of the Bible?

Several ancient texts are mentioned in the Bible but no longer exist, such as the Book of Jashar (Joshua 10:13), the Book of the Wars of the Lord (Numbers 21:14), and Paul’s earlier letter to the Corinthians (1 Corinthians 5:9). These texts were not “removed” from the Bible; they were never part of the recognized canon. They were historical sources or correspondence that the biblical authors referenced. Other texts like the Gospel of Thomas, the Gospel of Judas, and the Infancy Gospel of James are sometimes called “lost books,” but they were rejected by the early church as inauthentic or theologically incompatible with apostolic teaching. Most of these date to the 2nd century or later and were not written by the authors they claim.

Has the Bible Been Changed Over Time?

The evidence strongly suggests that the Bible has been transmitted with remarkable accuracy. The Dead Sea Scrolls demonstrated that the Old Testament text remained stable over more than 1,000 years of copying. For the New Testament, the sheer volume of manuscripts (over 5,800 in Greek alone) allows scholars to identify and correct copying errors with a high degree of confidence. The vast majority of textual variants are minor: spelling differences, word order changes, or easily identifiable scribal slips. No core Christian doctrine depends on a disputed textual variant. While the Bible was copied by hand for centuries before the printing press, the scribes who did the copying treated it as sacred work, and the manuscript evidence confirms their diligence.

The Bible’s journey from ancient scrolls to the book on your shelf is a story of faithful preservation across millennia. Whether you are reading Genesis or Revelation, you are engaging with texts that were carefully written, copied, and passed down through generations.
