Two Trees.
One Messiah.
"The book of the genealogy of Jesus Christ,
the son of David, the son of Abraham." — Matthew 1:1
Matthew and Luke each give us a family tree for Jesus — and they're different. Explore every person, every branch, and the biblical, theological, and historical evidence behind each name.

Why Two Different Genealogies?
Both Matthew and Luke include a genealogy of Jesus — but the names diverge after King David. This is not a contradiction. It is two authors, writing to two different audiences, making two different theological arguments about the same person.

Scholarship & Sources
Biblical, Historical & Theological Evidence
The two genealogies have been studied by scholars, historians, and theologians for two millennia. Here is the evidence that explains the differences.
Julius Africanus (c. AD 221)
The earliest scholarly explanation comes from Julius Africanus, who wrote to Aristides explaining the two genealogies through the Levirate marriage law. If a man died childless, his brother would marry the widow and raise children under the dead man's name (Deut. 25:5–6). This explains how one man (Joseph) could have two different "fathers" in two different lists.
The Mary/Joseph Theory
The dominant modern scholarly view (held by J.G. Machen, R.C. Sproul, Craig Blomberg, and others) holds that Matthew gives Joseph's legal line and Luke gives Mary's biological line. In Hebrew usage, "son-in-law" was often rendered "son," which explains why Luke calls Joseph the "son of Heli" — Mary's father, making Joseph his son-in-law.
The Davidic Covenant (2 Sam. 7)
God promised David that his throne would be established forever through his offspring. Both genealogies run through David — Matthew through Solomon (the royal kingly line) and Luke through Nathan (another son of David, 2 Sam. 5:14). Both satisfy the Davidic covenant from different angles: legal right and biological descent.
Matthew's 3×14 Structure
Matthew deliberately organizes his list into three groups of 14 generations. In Hebrew gematria, the letters of "David" (D-V-D) add up to 14. Matthew is making the theological point that all of history has been moving in perfect, God-ordained steps toward the Son of David. The structure is intentional, not accidental.
Luke's Universal Vision
Luke alone goes back to Adam, and then to God. This is theologically purposeful: Luke is arguing that Jesus is not merely the Jewish Messiah but the Second Adam — the restorer of all humanity. Paul develops this same theology in Romans 5 and 1 Corinthians 15. Luke's genealogy is the narrative setup for his entire Gospel's universal scope.
Women in Matthew's List
Matthew unusually includes five women: Tamar, Rahab, Ruth, Bathsheba, and Mary. All five have stories involving outsiders, scandal, or irregular circumstances. Scholars see this as Matthew's deliberate signal that Jesus' lineage includes Gentiles and the unexpected — foreshadowing the Gospel's reach beyond Israel.
Historical Timeline
From Abraham to Jesus
The genealogies span approximately 2,000 years of redemptive history — from God's covenant with Abraham (~2000 BC) to the birth of Jesus (~4 BC). Here are the key turning points.
~2091 BC
God's Call of Abraham
God calls Abram from Ur of the Chaldees and makes a covenant: "In you all the families of the earth shall be blessed" (Gen. 12:3). Both genealogies begin here — Matthew 1:1 opens with "son of Abraham."
~1010 BC
David Becomes King & the Davidic Covenant
God promises David an eternal dynasty: "Your throne shall be established forever" (2 Sam. 7:16). The Messiah must come from David's line. Both Matthew (through Solomon) and Luke (through Nathan) fulfill this requirement.
~586 BC
The Babylonian Exile
Jerusalem falls. The Davidic throne goes dark. Matthew marks this as the midpoint of his three groups: the exile is the great disruption. The line survives — but underground, through ordinary families.
~538–400 BC
Return from Exile & Post-Exilic Period
Zerubbabel leads the first return from Babylon. Both genealogies pass through Zerubbabel (Matt. 1:12–13, Luke 3:27) — one of the few points where the two lists briefly converge again after David.
~6–4 BC
The Birth of Jesus
Born in Bethlehem (fulfilling Micah 5:2) to Mary, a descendant of David through Nathan, and legally adopted by Joseph, a descendant of David through Solomon. Both legal right and biological descent meet in one person.
~AD 85–90
Matthew's Gospel Written
Written for a Jewish-Christian community, Matthew opens with the genealogy as a legal document establishing Jesus' credentials as the Messianic king promised to Abraham and David.
~AD 60–62
Luke's Gospel Written
Luke, a Gentile physician and companion of Paul, writes for a Gentile audience. He places the genealogy after Jesus' baptism and runs it back to Adam — framing Jesus as the universal Son of Man and Son of God.
