Matthew 1:13-17

and Zerubbabel the father of Abiud; and Abiud the father of Eliakim; and Eliakim the father of Azor;

and Azor the father of Zadok; and Zadok the father of Akim; and Akim the father of Eliud;

and Eliud the father of Eleazar; and Eleazar the father of Matthan; and Matthan the father of Jacob;

and Jacob was the father of Joseph, who was the husband of Mary, to whom Jesus was born, the one who is called the Messiah.

So all the generations from Abraham to David add up to fourteen; from David to the Babylonian exile, fourteen; and from the Babylonian exile to the Messiah, fourteen.
