Luke 2:15
When the angels had left them and gone into heaven, the shepherds said to one another, let's go to Bethlehem and see this thing that has happened, which the Lord has told us about — the shepherds' immediate response to the angels' departure is active: let's go and see. Not let's wait and think about this but let's go — the urgency of the response mirrors the urgency of the announcement. Which the Lord has told us about: they interpret the angelic announcement as the Lord's communication — the theological attribution is immediate.
