One of the most remarkable things about the Bible is the length of time over which it was written. Its books were composed over roughly 1,500 years, by around forty authors living in very different times and places. Yet Christians read it as one connected story.
The short answer
Most scholars who hold a traditional view place the earliest books of the Bible around the time of Moses — often dated to the 15th or 13th century BC — and the last book, Revelation, near the end of the first century AD (around AD 90–95). That gives a span of about 1,500 years. Scholars debate exact dates for many books, but almost everyone agrees that the Bible was written over many centuries, not in a single generation.
The Old Testament: about a thousand years
The Old Testament was written over roughly a millennium:
- The Law (Genesis to Deuteronomy) is traditionally linked with Moses, who led Israel out of Egypt.
- The historical books record events from Israel's entry into Canaan through the period of the kings, the exile to Babylon (586 BC) and the return.
- The Psalms were written over several centuries; many come from King David's time (around 1000 BC), others from later periods, including the exile.
- The prophets spoke and wrote from roughly the 8th to the 5th century BC.
- Malachi, usually placed around 430 BC, is the last Old Testament prophet.
Some books, such as Kings and Chronicles, were compiled over time from earlier court records and prophetic writings — the books themselves mention sources such as "the book of the chronicles of the kings of Israel" (1 Kings 14:19).
The silent years
After Malachi there is a gap of around four hundred years before the New Testament. During this period Persia, Greece and then Rome ruled the region, and the Hebrew scriptures were translated into Greek (the Septuagint) for Jews living around the Mediterranean.
The New Testament: about fifty years
By contrast, the New Testament was written in a much shorter period — within about fifty to sixty years after the death and resurrection of Jesus (around AD 30–33):
- Paul's letters are among the earliest New Testament writings, mostly from the AD 50s and 60s.
- The Gospels were written from roughly the AD 50s/60s to the 90s; Mark is often thought to be the earliest.
- Acts continues Luke's Gospel, describing the church's first three decades.
- Revelation, written by John on the island of Patmos (Revelation 1:9), is usually dated to the AD 90s.
This means many New Testament writings appeared while eyewitnesses of Jesus were still alive. Paul, writing to the Corinthians, mentions that most of the more than five hundred people who saw the risen Jesus were still living (1 Corinthians 15:6).
Why the long span matters
- Unity across centuries. Writers who never met each other, living in different cultures, contributed to one story of creation, fall, rescue and new creation. Christians see this unity as a sign of God's guidance.
- History unfolds step by step. God's plan is revealed gradually — from promises to Abraham, to the law, to the prophets, to Jesus.
- Context matters. Knowing when a book was written helps us understand it. A psalm written during exile, or a letter written from prison, reads very differently once you know the background.
A helpful way to picture it
If the Bible were a single family history, the earliest chapters would have been written by distant ancestors, and the final chapters by their descendants dozens of generations later — yet the whole story fits together.
