Two (2) father-son pair of Salathiel-Zorobabel.
Matthew1:12 KJV And after they were brought to Babylon, Jechonias begat Salathiel; and Salathiel begat Zorobabel, and Zorobabel begat Abiud.. (Note that Zorobabel is 'Son' of Salathiel)
Luke3:27 Which was the son of Joanna, which was the son of Rhesa, which was the son of Zorobabel, which was the son of Salathiel, which was the son of Neri,
1Chr3:17 And the sons of Jeconiah; Assir, Salathiel his son..
1Chr3:19 And the sons of Pedaiah were, Zerubbabel, and Shimei: and the sons of Zerubbabel; Meshullam, and Hananiah, and Shelomith their sister: [this the wrong Zerubbabel]
Ezra3:2 Then stood up Jeshua the son of Jozadak, and his brethren the priests, and Zerubbabel the son of Shealtiel (fn:Salathiel), and his brethren, and builded the altar of the God of Israel, [this the 'correct' Zerubbabel -- for the Matthew genealogy]
CONCLUSION: The father-son pair in Matthew and Luke are NOT the same persons, and there's an added Zerubbabel in 1Chr3:19. Rhesa/Neri different from Jechonias/Abiud..
Note the 2 spellings: Zorobabel, Zerubbabel -- but same in the two genealogies.
BONUS ROUND: the only other father-son pair that I've seen duplicated are Jacob/Joseph (Not just the Genesis well known pair, but also seen in Matthew 1:16 !!
The story of Rachel and Leah is much more than curious -- Rachel represents the Jews and the Old Covenant, while Leah represents the Gentiles and the New Covenant. Rachel (her name means "ewe") is barren at first, but figuratively is the one who births the Lamb of God, Jesus!
It's a paradox because the pedigree of Jesus actually comes through Judah, the 4th son of Leah. God saw the Jews first (and loved 'em), but its the Gentiles who are the 'Bride' !
Rachel sat on the sidelines while the first ten sons of Jacob were born, and then, finally, gave birth to Joseph, a type of Jesus. Later, she died giving birth to Benjamin, another type of Jesus because the name 'Benjamin' means 'son of the right hand'. Gen35:18.
