From the early Church Fathers to now.
“And they shall not take of thee a stone for the corner, nor a stone for foundations, but thou shalt be destroyed for ever, saith the Lord.”
“Prepare against her the nations, with the kings of the Medes,.... At the head of them, Darius and Cyrus. The Syriac version has it in the singular number, the king of the Modes: the captains thereof, and all the rulers thereof, and all the land of his dominions; that is, the inhabitants of it, the common people, with their princes, nobles, governors, as captains of them, under Cyrus, their generalissimo.”
“corner . . . stone . . . foundations--The corner-stone was the most important one in the building, the foundation-stones came next in importance (Eph 2:20). So the sense is, even as there shall be no stones useful for building left of thee, so no leading prince, or governors, shall come forth from thy inhabitants.”
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.
