Luke 2:16
So they hurried off and found Mary and Joseph, and the baby, who was lying in the manger — the hurrying (spesantes, moving with urgency) produces the finding. The specific detail of their finding — Mary, Joseph, and the baby lying in the manger — confirms the sign exactly as given: a baby wrapped in cloths, lying in a manger. The sign matches the announcement; the finding confirms the angelic word.
