After ¹  the deportation to Babylon, Jeconiah became the father of Shealtiel, ²  Shealtiel the father of Zerubbabel,

and Josiah ¹  the father of Jeconiah and his brothers, at the time of the deportation to Babylon.

So all the generations from Abraham to David are fourteen generations, and from David to the deportation to Babylon, fourteen generations, and from the deportation to Babylon to Christ, ¹  fourteen generations.
