From the early Church Fathers to now.
“Now I am afraid, lest the same thing should happen to me also: and whereas I am the only child of my parents, I should bring down their old age with sorrow to hell.”
“To hell. That is, to the place where the souls were kept below, before the coming of Christ; (Challoner) as the just had not yet access to heaven. See Genesis xxxvii. (Worthington) Greek adds, “and they have no other son to bury them.””
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.
