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 Savior, which is Christ the Lord.
The phrase “sore afraid” is a translation of the Greek word phobeō; it communicates the idea of, not just fear, but of taking alarm, and of sudden surprise. The shepherds, in other words, were terrified–not because, or at least not solely because, the appearance of the angel was a terrifying vision, but also because it was unexpected, and shocking. This was not something they ever could have been prepared for.
