Matthew 1:16-19

16Jacob was the father of Joseph the husband of Mary, by whom Jesus was born, who is called the Messiah (Christ).

17So all the generations from Abraham to David are fourteen; from David to the Babylonian deportation (exile), fourteen generations; and from the Babylonian deportation to the Messiah, fourteen generations.

18Now the birth of Jesus Christ was as follows: when His mother Mary had been betrothed to Joseph, before they came together she was found to be with child by [the power of] the Holy Spirit.

19And Joseph her [promised] husband, being a just and righteous man and not wanting to expose her publicly to shame, planned to send her away and divorce her quietly.
