Who is the last possible son of David who could be the King?

Les teaches that the family tree comes all the way down through history until Joseph on one side and Mary on the other, and Christ is the last possible son of David that could be the King. He explains that Christ makes His appearance to the nation of Israel, and that this is the whole idea of His first advent: He came to be that promised King according to the covenants. Les points out that Paul says this in verse 4 regarding his kinsmen according to the flesh, Israelites, to whom pertain the adoption, the glory, the covenants, the giving of the law, the service of God, and the promises. He notes God promised the nation over and over. Les also contrasts this with world opinion about those presently called Jews, whether in Russia, America, or the land of Israel, and directs attention to Deuteronomy chapter 4, verses 32 and 33.
