In the KJV Bible, the Christmas story begins with the prophecy of the coming Messiah. Then, the Angel Gabriel appears to Mary, a virgin, and tells her she will conceive by the Holy Spirit and bear a son named Jesus. Joseph, her betrothed, is visited by an angel in a dream and is reassured to take Mary as his wife. They travel to Bethlehem for a census. There, Jesus is born in a manger because there is no room in the inn. Shepherds in the fields are visited by angels who announce the birth of the Savior. Later, wise men from the East follow a star to find the baby Jesus and bring him gifts of gold, frankincense, and myrrh.
The key elements are Mary's virgin birth, Joseph's role, the journey to Bethlehem, Jesus' birth in a manger, the visit of the shepherds, and the arrival of the wise men.
The starting point of the Christmas story in the KJV Bible is found in Luke 2. It presents a vivid description of Jesus' birth, including the circumstances and the visitation of the angels to the shepherds.
The number of stories in the Bible is difficult to determine precisely. It depends on how you define a 'story'. Some might consider individual parables or events as separate stories, while others might group related incidents together. But in general, there are numerous accounts of various kinds.
It's hard to give an exact number. Different scholars and religious authorities might have varying counts based on how they categorize and define the stories.
