The purpose of publishing the Saviour's genealogy was to show that he had descended from David. If the genealogy of Mary had been given, it would have carried no weight with the Jews, as they would not admit the divine conception, and regarded Joseph as the head of the family. It was necessary, on their account, to show that Joseph had descended from David. It really, however, includes the others, as the descendants of David were so proud of their distinction, and of the Messianic promise involved, that no man of that family would take a wife of any other family. Mary, undoubtedly, therefore, was descended from David. The theory has been propounded and supported by Weiss and other scholars that the genealogy of Luke is that of Mary. Luke says (3:23)! that Joseph was the son of Heli, whereas Matthew says (1:16) that he was the son of Jacob. It is suggested that Luke's statement should read, "who was the son-in-law of Heli," that is, married the daughter of Heli. Luke traces the descent through David's son Nathan, while Matthew traces it through Solomon. Even that explanation, however, has its incongruities, of which there is no clear explanation. The fact that Mary before her marriage went to Bethlehem to be taxed or registered (Luke 2:5), would indicate that she was of David's house. It is noteworthy, too, that Christ's claims to Messiah ship were never challenged on that ground. If there had been any haw in his pedigree, the Jews would have seized upon it without a doubt, because the prophecies clearly stated that Messiah would be descended from David.
