From the early Church Fathers to now.
“A man that doth violence to the blood of a person, if he flee even to the pit, no man will stay him.”
“"A man who slanders blood," etc. Whether the land of the field or the land of the body, whoever cultivates it shall be satisfied; one with grain, the other with virtues. Whoever despises both shall be filled with poverty.”
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.
