Mat 1:17 So 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 unto Christ are fourteen generations.
Matthew 1:18
Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
Mat 1:20 And as he was thinking about these things, behold, an angel of the Lord was seen by him in a dream, saying, Joseph, son of David, do not be afraid to take Mary as your wife. For that in her is generated by the Holy Spirit.
