Arcana Coelestia # 10508
10508. 'Behold, My angel will go before you' means that Divine Truth will still be the leader. This is clear from the meaning in the highest sense of 'the angel of Jehovah' as the Lord's Divine Human, and in the relative sense as that which is Divine and the Lord's among angels in the heavens, dealt with in 1925, 2821, 4085, 6831, 9303, so that it means Divine Truth, 8192; and from the meaning of 'going before you' as being the leader.
Early
Since the sun represents the Lord, the early morning and sunrise represent a state of enlightenment with a new and clear understanding coming after a time of darkness. There are many ways this representation appears in modern life. For one, it’s long been tradition to orient churches with the sanctuary in the east, toward the rising sun. People grappling with a problem often decide to “sleep on it,” anticipating that answers will be more clear in the morning. And we actually use “dawn” as a verb for sudden enlightenment: “As he stared out the window, it dawned on him that the answer had been in his hands all along.”
