From the early Church Fathers to now.
“Give alms out of thy substance, and turn not away thy face from any poor person: for so it shall come to pass that the face of the Lord shall not be turned from thee.”
“Substance. Be not liberal of another’s property. Greek adds, “and let not thy eye be envious, when thou givest alms.” Do it generously. (Calmet) — The same doctrine of the reward of good works, occurs [in] Daniel iv. 24. (Worthington)”
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.
