Jesus was a Jew of the Tribe of Judah. He received His human nature from Mary, whose genealogy we find in Luke 3:23-31. His legal father, Joseph, was also descended from King David, through the royal line, through Solomon and the whole dynasty of kings of Israel and Judah, as recorded in Matthew 1:6-16. But the last king of Judah, Jehoiachin, was so wicked that he was cursed, in that none from his bloodline would ever again assume the Throne of David, in Jeremiah 22:30. So Joseph was not eligible to be the king, even though he was of the bloodline, because he was directly descended from Jehoiachin. But Mary's line came through King David's son Nathan, the brother of Solomon, who received the crown. So, Jesus inherited the Royal authority to the Kingship legally through Joseph, and directly through the bloodline of His mother Mary. Jesus alone could reign on David's throne.
Even so, come, Lord Jesus!
