Luke 2:7-9

and she gave birth to her Son, her firstborn; and she wrapped Him in [swaddling] cloths and laid Him in a manger, because there was no [private] room for them in the inn. In the same region there were shepherds staying out in the fields, keeping watch over their flock by night. And an angel of the Lord suddenly stood before them, and the glory of the Lord flashed and shone around them, and they were terribly frightened.
