Geneology of Jesus proving he is the Messiah

God said that the Messiah would come through the blood line of David, If follwed through marry's geneology (because she was a virgin we do not follow it through Joseph his father) we can see that marry's blood line descends directly from David.

Mary was a direct descendant of King David which gave Jesus the right to ascend the Jewish throne, both through Mary and through adoption by his foster father, Joseph. Mary’s genealogy is supplied in Luke 3:23-38
