“Heli was

The son of Matthat,

The son of Levi,

The son of Melchi,

The son of Jannai,

The son of Joseph.”

τοῦ Ματθὰτ τοῦ Λευεὶ τοῦ Μελχεὶ τοῦ Ἰανναὶ τοῦ Ἰωσὴφ

Luke said that Jesus’ grandfather was Heli.  From then on there is a major difference in the genealogies of Matthew and Luke.  A simple solution to this problem would be to say that Luke has presented the genealogy of Mary, not Joseph.  The father of Mary was Heli.  However, that does not explain where the names came from.  The end of the genealogy of Matthew, chapter 1:15, is Joseph with his father Jacob.  Most of the people mentioned in the genealogy of Matthew could be found in other biblical works.  However, where Matthew got these last 9 generations of names was unclear.  He must have had some source, since he was so meticulous following 1 Chronicles.  Zerubbabel was Abiud’s father.  Abiud was the father of Eliakim, while he was the father of Azor.  He, in turn was the father of Zadok, whose son was Achim.  His son was Eliud.  Eliud’s son was Eleazar whose son was Matthan.  Matthan was the father of Jacob, the father of Joseph.  None of those names are here as Luke said that Heli was the son of Matthat (τοῦ Ματθὰτ), the son of Levi (τοῦ Λευεὶ), the son of Melchi (τοῦ Μελχεὶ), the son of Jannai (τοῦ Ἰανναὶ), the son of Joseph (τοῦ Ἰωσὴφ).
