One concluding observation: Mason claims that “establishing some kind of connection with David might have been critical for a messianic figure…in Jesus’ time.” He writes: “A birth in Bethlehem, King David’s place of origin, would naturally cement Jesus’ Jewish messianic affiliation.” But during Jesus’ lifetime, belief that he was the Messiah did not require seeing him as the son of David (and therefore did not benefit from any connection with Bethlehem). In this period, the Davidic Messiah was not the only type of Messiah hoped for. Priest, prophet and teacher figures were also expected.[7](

36 None of these other messianic categories had any connection with Bethlehem. In consequence, Jesus could have been thought of as a Messiah without any reference to Bethlehem.
Furthermore, of the many different categories of Messiah, that of Davidic Messiah would have been the least likely match for Jesus in the eyes of his contemporaries. Indeed, Jesus’ behavior was the antithesis of that of a son of David, who was expected to be a warrior king who would rule with supreme authority. This hope is expressed most vividly in the first-century B.C. Psalms of Solomon.”

both Matthew and Luke achieved their objective, and that was all they needed to do. To prove that Jesus was descended from Abraham and David, it was not necessary to make a new genealogy. All they had to do was copy from the public tables that the nation fully accepted regarding the lineage of David and of the priesthood and all other matters requiring proof of one’s descent. (See Lu 1:5; 2:3-5; Ro 11:1.) Even if there was an omission in these tables, it did not detract from what these Gospel writers intended and indeed accomplished, namely, presenting legally and publicly recognized proof of the genealogy of Jesus the Messiah.
- Why do the genealogies of Jesus Christ as given by Matthew and by Luke differ?
The difference in nearly all the names in Luke’s genealogy of Jesus as compared with Matthew’s is quickly resolved in the fact that Luke traced the line through David’s son Nathan, instead of Solomon as did Matthew. (Lu 3:31; Mt 1:6, 7) Luke evidently follows the ancestry of Mary, thus showing Jesus’ natural descent from David, while Matthew shows Jesus’ legal right to the throne of David by descent from Solomon through Joseph, who was legally Jesus’ father.
Both Matthew and Luke signify that Joseph was not Jesus’ actual father but only his adoptive father, giving him legal right. Since Jesus was not the natural son of Joseph but was the Son of God, Luke’s genealogy of Jesus would prove that he was, by human birth, a son of David through his natural mother Mary.
