somewhere on these lonely hills came the vision of the angels, perhaps on the very spot where David was minding his sheep when Heaven summoned him to a higher task, passing him up among the kings. While the shepherds were "watching the watches of the night over their flock," as the Evangelist expresses it, referring to the pastoral custom of dividing the night into watches, and keeping watch by turns, suddenly "an angel of the Lord stood by them, and the glory of the Lord shone round about them." When the angel appeared to Zacharias, and when Gabriel brought to Mary her evangel, we do not read of any supernatural portent, any celestial glory, attending them. Possibly because their appearances were in the broad daylight, when the glory would be masked, invisible; but now, in the dead of night, the angelic form is bright and luminous, throwing all around them a sort of heavenly halo, in which even the lustrous Syrian stars grow dim. Dazzled by the sudden burst of glory, the shepherds were awed by the vision, and stricken with a great fear, until the angel, borrowing the tones and accents of their own speech, addressed to them his message, the message he had been commissioned to bring: "Be not afraid; for behold, I bring you good tidings of great joy which shall be to all the people: for there is born to you this day in the city of David a Saviour, which is Christ the Lord." And then he gave them a sign by which they might recognize the Saviour Lord: "Ye shall find a babe wrapped in swaddling clothes, and lying in a manger."
