Bede, on Ps 111:4

“To the righteous a light is risen up in darkness: he is merciful, and compassionate and just.”

“"Behold, an angel of the Lord stood by them, and the brightness of God shone around them." What does it mean that, as the angel was appearing to the shepherds, the splendor of divine brightness also enclosed them, something that we have never discovered in the whole course of the Old Testament? Though in countless cases angels appeared to prophets and just people, nowhere do we read of angels enclosing the human beings with the brightness of divine light. [Why is this], unless it is because the privilege was properly kept for the dignity of this time? For when the true Light of the world was born in the world, it was unquestionably fitting that the herald of his nativity should also bathe the bodily sight of human beings with the freshness of heavenly light. Now the prophet says concerning his nativity, "A light has arisen in the darkness for those who are righteous in heart." And as though we were asking what the light was to which he refers, he immediately goes on, "He is a merciful and compassionate and just Lord." Therefore, when the merciful and just Maker and Redeemer of the human race deigned to illuminate the world by the glory of a wondrous nativity, it was entirely proper that the brightness of a wondrous light should fill that very region in which he was born.”
