From the early Church Fathers to now.
“And we have not hearkened to thy commandments, nor have we observed nor done as thou hadst commanded us, that it might go well with us.”
“"Then the king promoted," etc. For as they honoured God by giving themselves up to death, so, too, they were themselves honoured not only by God, but also by the king. And they taught strange and foreign nations also to worship God.”
“Verse 30. "Then the king promoted Shadrach, Meshach and Abednego to honor in the province of Babylon." Those commentators who say that the three youths were previously not judges set over the provinces but mere overseers of individual government agencies in Babylon, would have it that they were now appointed as judges over the provinces.”
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.
