Catena Aurea · Lukasevangelium 2
And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord. And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.
(Geometer) He marks the time of our Lord’s nativity, when he says, To-day, and the place when he adds, In the city of David; and the signs thereof when it follows, And there shall be a sign, &c. Now the Angels bring tidings to the shepherds of the Chief Shepherd, as of a lamb discovered and brought up in a cave.
