Matthew 1:16-18

and Jacob the father of Joseph, the husband of Mary, and Mary was the mother of Jesus who is called the Messiah. Thus there were fourteen generations in all from Abraham to David, fourteen from David to the exile to Babylon, and fourteen from the exile to the Messiah. This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit.
