Matthew 1:14-20

14And Azor begat Sadoc; and Sadoc begat Achim; and Achim begat Eliud; 15And Eliud begat Eleazar; and Eleazar begat Matthan; and Matthan begat Jacob; 16And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ. 17So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon to Christ are fourteen generations.

18Now the birth of Jesus Christ was in this manner: When his mother Mary was espoused to Joseph, before they came together, she was found with child by the Holy Spirit. 19Then Joseph her husband, being a just man, and not willing to make her a public example, purposed to put her away secretly. 20But while he thought on these things, behold, the angel of the Lord appeared to him in a dream, saying, Joseph, thou son of David, fear not to take to thee Mary thy wife: for that which is conceived in her is by the Holy Spirit.1
