What does Luke 2:4 mean?
Joseph is engaged to Mary (Luke 1:26–27), who is expecting a child conceived by the Holy Spirit (Luke 1:30–33). They are travelling due to a government-ordered census (Luke 2:1–2). In this case, the census required people go to their ancestral hometowns (Luke 2:3). Jesus will be born here, fulfilling prophecy (Luke 2:6).Later, Luke will explain Jesus' genealogy. The later reference to Joseph as the "son of Heli" likely means son-in-law (Luke 3:23), meaning Luke's list seems to run the family line through Mary. This establishes Jesus as a biological member of David's line. As Jesus' earthly, adoptive father, Joseph would legally bring Jesus into the family line of David. Matthew's tracing of Joseph's genealogy confirms those details (Matthew 1:1–17).
