From the early Church Fathers to now.
“And when he was come to Rages a city of the Medes, and had ten talents of silver of that with which he had been honoured by the king:”
“Rages means “rupture,” by frequent earthquakes, and was (Menochius; Calmet) the residence of the Parthian kings, in spring, (Athen. xii. 2.) in the mountain, separating their country from Media. — Honoured for his salary. (Calmet)”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
