From the early Church Fathers to now.
“He that honoureth his father shall enjoy a long life: and he that obeyeth the father, shall be a comfort to his mother.”
“To the father, insofar as he holds the character of origin, the honor of reverence is owed; whence in Ecclesiasticus: He who fears God will honor his father and his mother, and will serve as masters those who begot him.”
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.
