From the early Church Fathers to now.
“Let the mountains hear the judgment of the Lord, and the strong foundations of the earth: for the Lord will enter into judgment with his people, and he will plead against Israel.”
“Lord's controversy--How great is Jehovah's condescension, who, though the supreme Lord of all, yet wishes to prove to worms of the earth the equity of His dealings (Isa 5:3; Isa 43:26).”
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.
