How Many Years From Adam to Jesus? About 4,000 or 5,500, and the Bible Gives No Total

The Bible never gives the total. Adding up the ages in its genealogies gives about 4,000 years from Adam to Jesus using the Hebrew text, and about 5,500 using the Greek Septuagint: a gap of roughly fifteen centuries.

Anyone offering a confident single figure is choosing a text and not saying so.

The famous number

James Ussher, Archbishop of Armagh, published a chronology in 1650 that put creation at the evening before 23 October 4004 BC.

He was a serious scholar and the work was careful. It was also printed in the margins of English Bibles for two centuries, which is how a seventeenth-century calculation came to look like part of the text.

It is not. No edition of Scripture in any original language carries a date.

Why the figure moves

The genealogies of Genesis 5 and 11 give each man’s age at the birth of his son. Adding them chains the generations together.

The problem is that the surviving manuscript traditions disagree about those ages.

The Hebrew Masoretic text, the Greek Septuagint and the Samaritan Pentateuch each give different figures, and the Septuagint’s are systematically longer. The cumulative difference from Adam to Abraham runs to something like 1,300 to 1,500 years.

These are not small copying slips. They are three coherent systems, and scholars have argued for centuries about which is original.

The other problem

Biblical genealogies do not always list every generation, and the New Testament proves it in a passage anyone can check.

Matthew arranges his genealogy in three sets of fourteen and says so explicitly (Matthew 1:17). To make the numbers work he omits people.

Between Joram and Uzziah in Matthew 1:8 there should be three kings — Ahaziah, Joash and Amaziah. They are in 2 Kings and 2 Chronicles, and they are not in Matthew.

He is not making a mistake. The Hebrew verb translated “was the father of” comfortably means “was the ancestor of,” and Matthew is building a pattern rather than a census.

Which means a genealogy cannot be assumed to be a complete chain, and the arithmetic depends on assuming exactly that.

So what can be said

Several things, honestly.

From Abraham forward the chronology is anchored to events with external evidence, and the broad shape is reasonably firm: Abraham somewhere in the early second millennium BC, the exodus disputed between roughly the fifteenth and thirteenth centuries, David around 1000 BC, the fall of Jerusalem in 586 BC — a date fixed by Babylonian records.

From Adam to Abraham the figure is whatever the chosen text and the chosen assumptions produce.

Christians hold a wide range of positions on the age of the earth, in good faith, and the genealogies are not the only thing in play. Saying so is more useful than pretending the sums are settled.

What the genealogies are for

They are not chronological tables, and reading them as such is reading past the point.

Genesis 5 is a chapter about mortality: nine paragraphs ending in the same five words, and then he died, with one exception where God takes a man away.

Matthew’s is an argument about who Jesus is: the son of David, the son of Abraham, with four women named in it whose stories are complicated — Tamar, Rahab, Ruth and the wife of Uriah.

Luke’s runs the other way, back past Abraham to the son of Adam, the son of God (Luke 3:38), which is the claim the whole list exists to make.

The lists are doing theology. The arithmetic is something later readers brought to them.

Frequently asked

How many years from Adam to Jesus?

Scripture gives no total. Adding the genealogies yields roughly 4,000 years using the Hebrew text and about 5,500 using the Greek Septuagint.

How many generations from Adam to Jesus?

Luke’s genealogy (Luke 3:23–38) has 77 names from Jesus back to God, which puts Adam 75 generations before Jesus. It includes Cainan between Arphaxad and Sala (Luke 3:36), a name found in the Septuagint’s Genesis 11 but not in the Hebrew. Matthew starts later and counts 42 generations from Abraham to Christ, in three sets of fourteen (Matthew 1:17).

Where does 4004 BC come from?

From James Ussher’s chronology of 1650, later printed in the margins of English Bibles. It is not part of the text.

Why do the manuscripts disagree?

The Masoretic text, the Septuagint and the Samaritan Pentateuch give different ages in Genesis 5 and 11, and the Septuagint’s are systematically longer.

Do biblical genealogies list every generation?

Not always. Matthew 1:8 omits three kings — Ahaziah, Joash and Amaziah — to keep his three sets of fourteen, and the Hebrew idiom permits it.

What are the genealogies for?

Argument rather than arithmetic. Genesis 5 is about mortality, Matthew’s about David and Abraham, and Luke’s runs back to “the son of Adam, the son of God.”
