Matthew 1:16-19

16and Jacob fathered Joseph the husband of Mary, who gave birth to Jesus who is called the Messiah.

17So all the generations from Abraham to David were fourteen generations; and from David until the exile to Babylon, fourteen generations; and from the exile to Babylon until the Messiah, fourteen generations.

18The birth of Jesus Christ came about this way: After his mother Mary had been engaged to Joseph, it was discovered before they came together that she was pregnant from the Holy Spirit.

19So her husband, Joseph, being a righteous man, and not wanting to disgrace her publicly, decided to divorce her secretly.
