The book about Jesus, son of David, Abraham and God.
There are 3 sets of 14 generations, from Abraham to David, from David to Israel's deportation to Babylon, and from the deportation to Jesus.
Mary was found pregnant before she married Joseph. The angel told Joseph it was all right, since it was of God, not man, and that this was to be the savior of Israel - from their sins. This fulfilled Isaiah 7:14.
A Roman census sends Joseph and Mary to Bethlehem, their city of origin. Jesus is born there, in the stable. Angels appear to nearby shepherds, heralding the good news. The shepherds go see Him, tell everyone there about the angels, and return worshiping God. Jesus is circumcised on the eighth day, and they fulfill the law at the temple regarding purification of mother and child. While there, Simeon and Anna see the Savior and bless God for Him. He is Israel's salvation, the Gentiles' revelation, Jerusalem's redemption, the rise and fall of many, the piercer of hearts.
