In Short
Luke 3:23–38 traces Jesus' family line backward from Joseph to Adam and ends with the words "son of God." Unlike Matthew, who starts with Abraham and moves forward through King Solomon, Luke runs the list in reverse, follows David's son Nathan instead of Solomon, and goes all the way back to the first human. The point is that Jesus belongs not only to Israel but to the whole human family. Luke places the genealogy between Jesus' baptism, where God calls him "my Son," and his temptation, where the devil says, "If you are the Son of God." Jesus is the true Son who succeeds where Adam failed.
"Jesus was about thirty years old when he began his work. He was the son (as was thought) of Joseph son of Heli..." (Luke 3:23, NRSV)
"...son of Enos, son of Seth, son of Adam, son of God." (Luke 3:38)
Why the Genealogy Comes Here
Matthew opens his Gospel with Jesus' family tree. Luke waits until Jesus is a grown man, about thirty years old, standing at the start of his ministry. See How Old Was Jesus When He Began His Ministry?
The placement is deliberate. Look at what surrounds it:
Luke 3:22, the baptism. A voice from heaven says, "You are my Son, the Beloved."
Luke 3:23–38, the genealogy. The list ends, "son of Adam, son of God."
Luke 4:3, the temptation. The devil says, "If you are the Son of God..."
Three times in a row, Luke puts the phrase "Son of God" in front of us. Adam was God's son in the garden and failed the test. Jesus, the new Adam, goes into the wilderness and passes it. Paul makes the same contrast: "For as all die in Adam, so all will be made alive in Christ" (1 Corinthians 15:22). See The Temptation of Jesus (Luke 4:1–13), Jesus the Second Adam, and Son of God, a Messianic Title of Jesus.
Luke's Genealogy vs. Matthew's Genealogy
| Feature | Matthew 1:1–17 | Luke 3:23–38 |
|---|---|---|
| Placement | Opening of the Gospel | After Jesus' baptism, before his ministry |
| Direction | Forward, from Abraham to Jesus | Backward, from Jesus to God |
| Starts or ends with | Abraham | Adam, "son of God" |
| Line through David | Solomon, the royal line | Nathan, another son of David |
| Joseph's father | Jacob (Matthew 1:16) | Heli (Luke 3:23) |
| Number of generations | 42, in three groups of fourteen | About 77, depending on the manuscript |
| Women named | Tamar, Rahab, Ruth, Bathsheba ("wife of Uriah"), Mary | None |
| Main emphasis | Jesus as Son of David and Son of Abraham, Israel's King | Jesus as Son of God and Son of Adam, Savior of all people |
The two lists nearly match from Abraham to David. Between David and Joseph they share only two names, Shealtiel and Zerubbabel. For more, see the Matthew 1 Chapter Summary and Outline and Genealogies in the Bible: From Adam to Jesus.
Why Are the Two Genealogies Different?
Christians have noticed the differences since the early church. There are three main explanations, and faithful scholars hold each one.
Luke gives Mary's line. On this view, Heli was Mary's father, and Joseph is called "son of Heli" as his son-in-law. Luke's birth story is told from Mary's side, which makes this attractive. The weakness is that Luke never names Mary in the list.
Levirate marriage. Around 220 CE, Julius Africanus (quoted by Eusebius) suggested that Jacob and Heli were half-brothers. When one died childless, the other married his widow, as the Law allowed (Deuteronomy 25:5–6), so Joseph had a legal father and a biological father.
Legal and natural lines. Matthew traces the royal line of succession, the official heirs to David's throne. Luke traces Joseph's actual family descent. The two lines diverge at David and briefly cross again at Shealtiel and Zerubbabel.
No explanation solves every detail, and ancient genealogies were not written like modern birth records. They often skipped generations and were shaped to make a theological point. What matters most is that both Gospels agree on the essentials: Jesus is a true descendant of Abraham and David, and Joseph was his father only "as was thought" (Luke 3:23).

Walking Luke's Family Tree Backward
Luke's list reads like climbing down a well, generation by generation, until you reach the bottom of human history and find God there. Here are the stretches of the journey and the people who stand out along the way.
Joseph to Zerubbabel: Ordinary Names (3:23–27)
Most of the names in this stretch appear nowhere else in Scripture: Heli, Matthat, Levi, Melchi, Jannai. They were carpenters, farmers, and householders whose lives left no record. Luke includes them anyway. God's promise traveled through people history forgot.
Joseph. Luke is careful: Jesus was "the son (as was thought) of Joseph" (3:23). Joseph was not Jesus' biological father, but he raised him, protected him, and gave him a name and a place in David's line. Fatherhood in Scripture is more than biology. See Joseph Trusted God and Joseph: The Daring and Quiet Strength of Christmas.
Zerubbabel and Shealtiel (3:27). Zerubbabel led the first exiles home from Babylon and rebuilt the temple (Ezra 3:8; Haggai 1:1). His place in the line says that even exile could not break God's promise. After judgment, God restores.
Nathan to David: The Unexpected Branch (3:31)
Nathan. Here Luke takes a surprising turn. Matthew follows King Solomon, the son who built the temple and wore the crown. Luke follows Nathan, another son of David and Bathsheba (2 Samuel 5:14; 1 Chronicles 3:5), who never ruled. This Nathan is not the prophet Nathan who confronted David, though the names are easy to confuse. See Nathan the Prophet, David, and Psalm 51. Through a quiet, uncrowned branch of the family, God brings the King.
David. Israel's greatest king, a man after God's own heart who also failed terribly. God promised him, "Your house and your kingdom shall be made sure forever before me" (2 Samuel 7:16). Jesus is the fulfillment of that promise. See Who Was David in the Bible? and Son of David, a Messianic Title of Jesus.
David to Abraham: The Covenant Family (3:32–34)
Boaz (3:32). The kinsman-redeemer who married Ruth, a Moabite widow, and became David's great-grandfather. Luke does not name Ruth, but anyone who knows the story hears her in Boaz's name. A foreigner is folded into the Messiah's family. See Who Was Ruth in the Bible? and How Jesus' Surprisingly Scandalous Family Tree Is Good News.
Judah (3:33). Far from a model son, yet Jacob blessed him: "The scepter shall not depart from Judah" (Genesis 49:10). Jesus is the Lion of the Tribe of Judah (Revelation 5:5).
Jacob (3:34). The schemer who wrestled with God and walked away limping, renamed Israel. God keeps choosing imperfect people. See Who Was Jacob in the Bible?
Isaac (3:34). The son of promise, born when Abraham and Sarah were far too old. On Mount Moriah, God provided a ram in Isaac's place (Genesis 22:13–14). Isaac's near-sacrifice points ahead to the Son God would not spare. See Who Was Isaac in the Bible?
Abraham (3:34). God called him with a promise for the whole world: "in you all the families of the earth shall be blessed" (Genesis 12:3). Matthew begins here. Luke passes right through, because Abraham was never meant to be the end of the story. The blessing was always for every family on earth. See Who Was Abraham in the Bible?, The Going of Abraham and Sarah (Genesis 12:1–4), and God of Abraham, Isaac, and Jacob.
Abraham to Adam: The Whole Human Family (3:34–38)
Noah (3:36). God saved Noah's family through the flood and made a covenant with "every living creature" never again to destroy the earth by water (Genesis 9:10–11). Every nation descends from his sons. See Noah's Ark and the Flood and When Did Noah Live?
A detail for careful readers. Luke lists a Cainan between Arphaxad and Shelah (3:36) who does not appear in the Hebrew text of Genesis 11:12. He is in the Greek Old Testament (the Septuagint), which Luke usually quotes. Luke was following the Bible his Gentile readers knew.
Adam (3:38). The first human, made by God's own hand. His disobedience brought sin and death into the world. "Just as one man's trespass led to condemnation for all, so one man's act of righteousness leads to justification and life for all" (Romans 5:18). See When Did Adam and Eve Live?
God (3:38). The list does not end with a human being. It ends with the Creator. Every name on the list, and every name not on it, traces back to the God who made humanity in his image.
[Pastor's heads-up: add a short personal note about your own family tree, or a congregant's, and what it means that God works through ordinary generations.]
What the Genealogy of Jesus Means
Jesus belongs to everyone. By going past Abraham to Adam, Luke says Jesus is kin to every human being, Jew and Gentile alike. This is the same Gospel that quoted Isaiah, "all flesh shall see the salvation of God" (Luke 3:6).
God keeps his promises across centuries. Abraham, David, and Zerubbabel never saw the fulfillment of what God promised them. The promise outlived them all and arrived on time.
Grace runs through imperfect people. Schemers, foreigners, exiles, and unknown names fill this list. God's story does not depend on a flawless family. That is good news for yours and mine.
Jesus is the faithful Son. Adam, "son of God," fell. Jesus, the beloved Son, stands. In him, humanity gets a new beginning.
Your story is in this story. If Jesus is a son of Adam, then he shares our flesh, our history, and our struggle. "Since, therefore, the children share flesh and blood, he himself likewise shared the same things" (Hebrews 2:14).
The Genealogy and the Book of Acts
Luke's second volume picks up the themes of his family tree.
One human family. In Athens, Paul tells the philosophers, "From one ancestor he made all nations to inhabit the whole earth" (Acts 17:26). That is Luke's genealogy in a sentence. See Acts 17 Outline, Summary, and Meaning.
The promise to David kept. Peter preaches at Pentecost that David "knew that God had sworn with an oath to him that he would put one of his descendants on his throne," and so foresaw the resurrection of the Messiah (Acts 2:30–31). See Jesus Crucified and Raised (Acts 2:22–36).
The blessing to Abraham shared. Peter tells the temple crowd, "You are the descendants of the prophets and of the covenant that God gave to your ancestors, saying to Abraham, 'And in your descendants all the families of the earth shall be blessed'" (Acts 3:25). See Peter Speaks to the Onlookers (Acts 3:11–26).
From Abraham to Jesus. Paul's sermon in Pisidian Antioch walks through Israel's history and declares, "Of this man's posterity God has brought to Israel a Savior, Jesus, as he promised" (Acts 13:23). See Acts 13 Outline, Summary, and Meaning and Acts as the Second Volume of Luke.
FAQ
Why does Luke trace Jesus' genealogy back to Adam? To show that Jesus came for all humanity, not just Israel. Adam is the father of every human being, so Jesus is related to everyone.
Why does Luke call Adam the "son of God"? Adam had no human father. He was created directly by God. The phrase also sets up the contrast between Adam, who failed, and Jesus, the Son of God who obeys.
Why are Matthew's and Luke's genealogies different? The three main views are that Luke gives Mary's line, that levirate marriage gave Joseph a legal father and a biological father, or that Matthew traces the royal line while Luke traces the natural line.
Is Luke's genealogy Mary's or Joseph's? Luke names Joseph, but many interpreters believe it reflects Mary's family, with Heli as her father. The text does not settle the question.
Why does Luke go through Nathan instead of Solomon? Luke follows the actual family line, which ran through Nathan, another son of David. It also fits Luke's theme of God working through the humble rather than the powerful.
How many generations are in Luke's genealogy? About seventy-seven, from Jesus back to God, depending on the manuscript.
How old was Jesus when he began his ministry? "About thirty years old" (Luke 3:23).
