“Another. Behold the grand maxim of fraternal charity, Matthew viii. 12. Alex. Severus was so much pleased with it, that he had it often repeated by a herald, and inscribed on public edifices. What thou wouldst not have done to thee, do not thou to another. (Lamprid.) — Greek and Hebrew add a caution against drunkenness and drunken companions. Fagius has another against revenge; and the old Vulgate, “give not way to wickedness.””

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.
