Rom. 9:29

"And as Isaiah said before, 'Except the Lord of Sabaoth had left us a Seed, we had been as Sodom, and been made like unto Gomorrah.' " — Rom. 9:29

The capitalization above is mine; I don't think this verse can be understood unless you do capitalize "Seed." Except for the sake of the line of Messiah, the seed that was passed from generation to generation, God would have destroyed Israel just as He destroyed Sodom and Gomorrah. At each step of history, from Abraham to Jesus, God preserved the Jewish nation for the sake of the single man carrying the seed: Abraham, Isaac, Jacob, Judah, Perez, Hezron, Arni, Amminadab, Nahshon, Salmon, Boaz, Obed, Jesse, David, Nathan, Mattatha, Menna, Melea, Eliakim, Jonam, Joseph, Judas, Simeon, Levi, Matthat, Jorim, Eliezer, Joshua, Er, Elmadam, Cosam, Addi, Melchi, Neri, Shealtiel, Zerubbabel, Rhesa, Joanan, Joda, Josech, Semein, Mattathias, Maath, Naggai, Esli, Nahum, Amos, Mattathias, Joseph, Jannai, Melchi, Levi, Matthat, Heli, and then Mary. "And I will put enmity between you and the woman, and between your seed and her Seed ..." (Gen. 3:15)
