While they were in Bethlehem, the time came for her to be a mother; and Mary gave birth to her firstborn son, wrapped him in swaddling clothes and laid him in a manger, because there was no room for them in the shelter. In that region, some shepherds camped, who took turns watching over their flocks during the night. 

Suddenly, the Angel of the Lord appeared to them and the glory of the Lord enveloped them with its light. 

They felt great fear, but the Angel told them: “Do not be afraid, because I bring you good news, great joy for all the people: Today, in the city of David, a Savior has been born for you, who is the Messiah, the Lord. And this will serve as a sign: they will find a newborn child wrapped in swaddling clothes and lying in a manger.”

 The star marks the place where the Child Jesus was born.
