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. The angel of the Lord came upon them - Or, stood over them, επεστη. It is likely that the angel appeared in the air at some little distance above them, and that from him the rays of the glory of the Lord shone round about them, as the rays of light are projected from the sun.
They were sore afraid - Terrified with the appearance of so glorious a being, and probably fearing that he was a messenger of justice, coming to denounce Divine judgments, or punish them immediately, for sins with which their consciences would not fail, on such an occasion, to reproach them.
