keepingwatch over their flock by night.     And, lo, the angel of the Lord came upon them, and the     glory of the
Lordshone around them; and they were      sore afraid. And the angel said unto them, " Fear not;     for behold I bring
yougood tidings of great joy which     shall be to all people. For unto you is born this day      in the city of David
