Then the angel said to them, "Do not be afraid, for behold, I bring you good tidings of great joy which will be to all people. For there is born to you this day in the city of David a Savior, who is Christ the Lord. And this will be the sign to you: You will find a Babe wrapped in swaddling cloths, lying in a manger." And suddenly there was with the angel a multitude of the heavenly host praising God and saying:

"Glory to God in the highest,
And on earth peace, goodwill toward men!"

So it was, when the angels had gone away from them into heaven, that the shepherds said to one another, "Let us now go to Bethlehem and see this thing that has come to pass, which the Lord has made known to us." And they came with haste and found Mary and Joseph, and the Babe lying in a manger. Now when they had seen Him, they made widely known the saying which was told them concerning this Child. And all those who heard it marveled at those things which were told them by the shepherds. But Mary kept all these things and pondered them in her heart.

[Luke 2:10–19]
