From the early Church Fathers to now.
“One of you shall chase a thousand men of the enemies: because the Lord your God himself will fight for you, as he hath promised.”
“For faithful is he who has promised that "a thousand shall be chased by one," and that "ten thousand shall be put to flight by two," victory in battle being due not to numbers but to righteousness.”
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.
